Miklukhin and L.A. Belousov in Uteynoye proizvodstvo", 1959, Nr 8. The author states that this method was already developed and tested by the department for silicon-alloys of the .!-Z&poTozhry* ferro-alloys plant, together with the Dne- propetrovsk Metallurgical Institute and the Dnepro- petrovsk Grey Iron Rolling 21ant. This alloy was found inadequate. The author proposes - for the si- licon-magnesium alloys a- the method which was de- vel d by A.Ye. Krivosheyev, Delay and I.S.

The pieces were studied by chemical, petrographic, and miner-,Llogic analysis. It has been proven by such analysis and laboratory experiments that not only silicon oxide but also silicon carbide fo--m side produote. Silicon c&rbide was present in most of the specimen part2, beginning with the top and ending with the bottom levels in the furnaces, alor9with a great quantity of compl":& minerals.

A smaller number of vertical seams on the electrode casing reduced the coking of the contact surfaces of bronze shoes; the electric contact between shoe and electrode and the useful life of shoes improved, the removal of electrodes was simplified,.the repair time of the furnace shortened. 2) Better results were obtained with melting metal manganese from granulated silicomanganese (0-20 mm) than with crushed silicomanganese. The kinetic conditions of reactions improv- ed, increasing the furnace output by 4-5% and reducing electric power consump- tion. 3) Tests were carried out with melting of ferrochrome (YPOOC), YPOO = KhrOOO, KhrOO) by adding various amounts of silicochrome in the furnace bottom, before char-Ing, between 300 and 1,100 kg per charge. The best results were obtained with 800 kg in a charge of doubled quantity. By feeding silicochrome on the furnace bottom and doubling the amount of charge, output was raised by Card 1/4 68497 News in Brief S/133/60/000/012/007/015 A054/AO27 5%, extraction of chrome increased by 4-5% and power consumption decreased from 2,592 to 2,317 kwh/ton. 4) The optimum composition of slag was inyestigated for melting commercial grade silicomanganese, adding 20,30 and 40 kg of dolomite in the char,~,e afterwards. Optimum results were obtained with 30 kgz the basi- city of the olag was raised from 0.2 to 0.4 and the yield of manganese from 74.9 to 84.7/o, the furnace output was increased by 6P" and the specific power consump- tion was reduced by 6!o. 5) The losses in ferrochrome in form of sow and scrap were about 1.5-10,16 of the weight of the melt. These losses increased when the lime was not roasted sufficiently, when melting time was extended and when the metal was not evenly poured. In order to reclaim the metal from the slag of -the first ladle, the slag was kept separately on the damping place. 6) Ton series of industrial scale tests were carried out with meltings having various contents of different slag thinners. As a result, the consumption of expensive fluorite could be lowered from 90 kg/ton to 30 kg/ton by subs-tituting lime for fluorite. The cost of refined ailicomanganese could thus be decreased by 50 rubles/ton. 7) A new composition of agglomerate, consisting of Polozhsk sand and iron ore was tested on an industrial scale, melting 45 and 75,4) ferrosilicium. The furnace output was not raised but the sand-ore agglomerate proved to be satia- factory in melting ferrosilicium in closed ferro-alloy furnaces, when the agglomerate consisted of particles of the 50-150 mm fraction. 8) In order to Card 2/11, News in Brief 88497 S/13 60/000/012/007/015 A054YI1027 improve the method to determine small amounts of carbon in chrome alloys, silicochrome samples with 0.02-0-031o C content and ferrochrome samples with 0.06,~~' C content were roasted under various conditions. The moot complete burning of 0-when present in small amounts. wag attained in silicochrome and ferrochrome when using Wood's alloy at II370-1,3800C. 9) In order to reduce the carbon content of silioochrome to 0.020f. and less, several methods were tested. The beat results were obtained with two methods combiaedt increasing the holding time in the ladle before pouring to 1.5-2 hours and pouring through the lower hole of the ladle, or: pouring the metal from one ladle, after a holding time of 20 minutes, into another and holding it there for 40 minutes and screening out the -2 mm fraction after crushing. By these methods silico- chrome can be obtained for the production of ferrochrome with a C-content of 0.060A. 10) Tasts were carried out to produce Yp (Khr) 0000 type forrochrome with low C-content. Optimum results were obtained when one charge contained 1,700 kg ores and silicoohrome of the first charge was fed on to the furnace bottom, while silicochrome of the second charge was added into the melt. Voltage was reduced from 500 to 285 Y, the carbon content of the initial sili- cochrome was decreased and it was possible to obtain regularly ferrochrome of the KhrOOOO brand with a C-content below 0.06GA. 11) Tests were made in order to establish the optimum heat conditions of lime kilns and it was found that Card 3/4 News in Brief underpressure at the chimney aspirator should be the roasting zonat 20-25 mm water column; gas 3p250 hm3/h at a heat output of 2,100 cal/hm3, each burner, the distribution of the gas supply burner.

Stall, no. 1, 1962, 43 TM- ; A new method for smelting carbon-free ferrochrome in staLionary 3,500 IM arc furnaces (with 420-mm diameter electrodes) was tested, The charge consisted of 11,000 kg chrome ore (55% Cr~O ) 1 620 kg silicochrome (50% Si) and 3,800 kg lime, (90% CaO). The new method ~i~fe;ed from the conventional one in that silicochrome is fed in two batches: one on the furnace bottom (varying 11q xnourLt), while the second part of silicochrome Is added aftev the charE;e ore and I Ime) Is smelted. 450 tests were made with Xp 0000 (Khr 0000) f er! o- chrome. By adding part of the silicochrome onto the bottom of the furnace, a great amount of the heat released by the heating of silicochrome could be utilized for smelting the charge, whereas when silicochrome was added later to the Charge, the heat developed by the burning silicochrome is only wasted on the overhea'UnF; o'll the charge already smelted. Optimum results were obtained when about half of Card 1/2 3/133/62/000/001/004/010 Improving the smelting technologies of ... A054/A127 mbe silicochrome (800 kg) was placed on the furnace bottom and half of it added to I'he charge. When less than 50% of silicochrome was fed onto the bottom, VnF, sme"~_ Ing, of ~ne charge was delayed; adding move, the furnace lining was affecled due intensive smelting of' the charge. When about 50% or the total !,ilicnchrom,% was addea, a considerable amount. of siliclum developed, on account of the r-ed'ic- ol ohrome and ferro-oxides. This decreased the basicity of the slag tMd lt,s 5melt.ing temperal;ure. Adding silleochrome in two batches reduced the m,~4~cill r)-Qrn 4 - '5 to 2 - 3% of -the smelt.

For this purpose, after the furnace is put into operation, the amount of small coke in the first two charges must be 20 - 30% lower than pre- Mribed. Improper furnace operation can be observed immediately from the drop in CO concentration and increase in the H content of the gases, indicating water leakage from the cooling system, the c;itical H-content being 12%.

ABSTRACT3 The corona loss is only connected with the reactive currents of the lines. A diagram shows a one-phase line and an antenna earthed exactly in the middle above a measuring element. '2he potential supplied to the antenna is distributed in such a way that one magnitude in the center of the antenna is equal to zero. Thus the charge of such an antenna depends on the charge on the surface of the line as well as on the corona-space cbarge. The proportionality coefficient is a constant magnitude and is determined by the geometric measurements of the antenna as well as by the measurements which characterize the mutual position of antenna and line. This makes it possible to carry out the measurements of the corona losses by means of antennae. A sym- metric distribution of the corona-space charSe in relation to the line axis was assumed and experimentally checked in the laboratory. The data obtained this way were compared with the Card 1/2 corona losses of direct measurements and coincided well with them. Measuring Corona Losses on Lines in Service. Thus the investigation proved the possibility the corona losses of lines in service by means (With 8 illustrations and 1 Slavic reference). 105-7-7/29 of measuring of antennas.

TITLE: The theoretical measuring power S/024/61/COO/003/011/012 E140/E463 (Moscow) justification of the antenna method of loss in ac-corona PERIODICAL: Izvestiya Akademii nauk SSSR, Otdeleniye tekhnicheskikh nauk, Energetika i avtomatika, 1961, No.3, pp.126-133 TEXT: The antenna method for measuring ac-corona power loss (Ref-1: Kravchenko V.D., Levitov V.I., Popkov, V.I., Elektrichestvo, 1957, No-7) is based on the fact that the potential of antennas extended parallel to the conductors of the lines emitting corona, outside the space-charge region are defined by the same equations in Maxwell potentials as before the formation of the corona. By the charge of each emitting conductor in these equations is understood the sum of charges directly on the intials conductor and in the space charge surrounding it. The pote are calculated in the same way as before formation of corona, front the mutual positions of the conductors and antennas. Adding to these equations, further equations flowing from the condition of grounding of the antennas, it is possible to express the total charge of the corona emitting conductors (qA, qB, qC) by the Card 113 C j lo I S/024/61/000/003/011/012 The theoretical justification 9140/E463 antenna potentials. This permits finding the charges of the corona emitting conductors and thus the power loss P, equal to P = 1 (U dq d + UCdqC) T ~ A A + UB PB (T) if the conductor potentials (UA, UB, UC) can be measured. To apply the potential equations in the presence of corona in Ref.1 it was stated that it was necessary for the space charge of each conductor to be plane-parallel and radially symmetrical with respect to the conductor at all times. In effect, with these conditions respected, the field outside the space charge region is identical to the field of the same charge concentrated on the axis of the corona emitting conductors, which lead to the same equations for the antenna potentials. The condition of plane-parallel and radial distribution of the space charge does not in general correspond to reality, since the corona discharge, especially on thick conductors, occurs in the form of individual brushes. At the same time the process also has a discrete structure in time, occurring in the form of individual high frequency impulses. it Card'2/3 4J-LO3 S/024/61/000/003/011/012 The theoretical justification ... E14O/E463 is therefore necessary to determine if the above conditions are necessary for the potential equations to be applicable, or if It is possible to extend the class of cases where they are valid. It is also desirable to find the possibility of estimating the error introduced by deviations of the space charge distribution from the ideal. The article solves thin problem by the method of calculating charges induced in a plane parallel system of electrodes by a given three-dimensional space-charge distribution. The method is applied to an antenna located para'Llel to the earth. The results are extended to the case of multiple antennas, There are I figure and 4 Soviet references.

Under vibration the 'ntensity of the steel ebullition in the mold was increased notably, the rising was reduced and the thickness of sound crust was Increased. Depending.on the duration of the vibration it is possible to obtain any given thickness of dense crust, since in order to obtain ingots with 25-30 mm occurrence depth of cellular bubbles it is sufficlent to subject them to vibration for 5-6 min from the moment the pouring starts. Under 7 minute vibration the cellular bubbles were situated at a distance of 42 mm from the surface and under vibration for, 24 min 20 sec they vanished.

A060/A101 During the time of experiment 426.8 liters of gas was liberated (the crust thick. ness being 8 mm) from an ord-inary ingot, and 576.4 liters - from the experimental ingot. In vibrated Ingots the thickness of the crust does not depend on the po'.Ir- ing rate, thus In pouring through 30 and 50 mm sockets (filling rate 0.87 and 1.8 meters per min) the vibration lasted 8 min, the crist thi..,kneas in both cases was obtained as 35 mm, whereas for ordinary ingots the crust thickness was 6 and 8 mm respecl~ively. However, vibration is accompanied by undesirable processes-. a certain increase in 'the amount of negative segregation, leading to the. utilIza- ticn of a considerable portion of the metal (up to 30%) for less important ar~ic,_'es. An increase in the duration of the bubbling of vibrated ingots by 2-5 min over the usual period m&kes it possible to eliminate this disadvantage in the r-ase that the vibration proceeds for 5-6 min.

Yampoll skly. Moscow. 1,961, 258-Z73. TEXT: It is important to obtain a rimmed ingot with an external skin > 8 mm thick to protect the honeycomb blowholes from oxidation during soaking in pits. High-grade ingots with up to 0. ZYsC were obtained at plants in the Urals. To accele- rate the rate of pouring and to improve the quality further, a vibrator designed by the Moscow Steel Institute was used in experimental castings. An a. c.-Motor-driven eccentric vibrator was mounted on'th6 platform of a 50-ton casting car and was operated at approximately 1. 500 cpm and at amplitudes which varied from 0. 4-0. 8 mm to 1. S- 1. 8 mm, depending on the elasticity of the track and the change in load on the car. Vibration times varied from Z 145" to Z41 20"; test runs were timed at various stages of the casting processo and the capping of the ingots was done Card 1/3 Influence of vibration on the formation...

Longitudinal sections were photographed, and samples were cut from the 'a, 5, 8, Us 13, 15, 17, ZO, and 25% horizons, as measured from the top of the ingot. Templets were cut for mctallography, the templets were deep-etched. sulphur- printed, and chemically analyzed. A detailed description is given of the casting process# and the composition of the test melts is tabulated. The results of the casting of 7-ton ingots at various time rates, with and without vibration, are also tabulated. The character of the rimming of ingots subjected to vibration is shown to be greatly altered, and shortly after commencement of the vibration the rimming becomes violent, to the point of gushing and spraying. Instead of the ordinary peripheral rimming of steel GT. 3 (St. 3) along the interface ot the liquid and solid phase, the vibrated steel rims all over. Contrary to the continuous growth of brdinary ingots. which begins 1-2 min after the pouring is stopped, vibrated irgots sag 30-50 mm, and c,% en up to 100 mm, within 7-8 min and then grow slightly, but never back to. their initial level, unless the vibration is stopped prematurely. As to structure, vibr,ition eliminates the ordinarily observed difference between the upper and the lower part of the ingot; however, oome tendency toward the formation of cracks in the lower part of the ingot is observed. *In the ordinary ingots at the plants the dense external skin is 8-15 mm thick (thicker with slower pouring and with lower Mn content) - The length of the honeycomb blowhole a is about 8 0- 100 nun; the Card 2/3 Influence of vibration on the formation... S/737/61/000/000/OOZ/010 secondary blowholes are spherical and lie at 100- 125 mm from the outer surface, forming a vertical lace up to the rising part of the ingot. Vibration causes dis- appearance of the blowholes, going fiom the periphery toward the center and thick-. ening the skin. 10- 12 min of vibration results in a total disappearance of the blow- holes. However. the zone formerly occupied by the primary honeycomb blowholes is always occupied by sparse small, circular* bubbles, I - 4.5 mrn dia, some 5- 10 mm apart. Macrostructurally, vibration is conducive. to a d0placement of the shrinkage porosity into the depth of the Ingot. Vibration affects the distributiun of -9des only very little. Vibrat -re the remnants ed ingots have sulfide veins that of Q-4 now-filled blowholes. Spot-sample analysis at various depths shows that the li,4--.;ating-element content, in the outer zone remains equal or is even increased by ,'the -vibration. C, S, and P contents in the outer zone are not appreciably affected Py vibration.* Both the zone of concentrated liquation and the zone of porosity are J-~;cated more deeply in vibrated ingots, as shown by chemical analysis. In summary, .vibration affords production and faster pouring of a rimmed steal with a higher. C content and an Improved production of semikilled steel.

The paper is an experimental study of oblique emission of electromagnetic -waves by an active plane-parallel surface bounded by an ideally conducting screen on one side and by a metal grating on the other. Expressions are given for the electric and magnetic fields in the plane-parallel layer and in the ambient medium. Boundary conditions are stated and the electradynamic boundary problem is reduced to a Riemann. Hilbert problem for an analytic function. The solution of the problem reduces to an infinite homogeneous system of linear algebraic equations which is convenient for computer calculations. Conditions for self-excitation of the layer are given. An analysis of the expressions for the basic energy characteristics of the layer shows that the effective reflection coefficient, parameters of the ambient medium, and angle of wave propagation have a considerable effect an these characteristics. When the Cord 1/2 UDC: .5.35.5 L 10907-66 ACC W AP6001484 parameters for the gratings are disregarded, the proposed analytic expressions agree satisfactorily with studies by other authors vhich have been experimentally con- fimed.

A. Tretlyakov, V. P. Shestopalov, Opt. i spektr., 15, 709, 1963), in which the authors considered radia- tion by an active plane-parallel layer with adjacent grids where the vector E of the ~electromagnetic field is parallel to the generatrices of the grid elements. The au- thor of the present article gives a strict Qo~ut.J= for the problem of the effect which the grid parameters have on radiAig by 6e active plane-22rallel layer. It is assumed that metal grids are appTled symmet ically to both sides of the layer and .that the vector H is parallel to the generatrices of the grid elements. Conditions .Card 1/2 UDC: 53S.2.001 L 1356o.M ACC NR: AP6004413 ~for self-excitation are derived as well as the fundamental power characteristics: .energy density and radiation output power. The analytical expressions derived in ,this paper are convenient for numerical calculations on a computer and show that the power radiation characteristics of a layer may be controlled by proper selec- .tion of the geometric dimensions of a metal grid applied to the layer.

This paper investigates the effects of REM on specific properties of steel, notes procedures for alloying steel, and indicates optimum REM content to achieve desired combinations of mechanical properties. Chemical thermodynamic data and composition of REM alloys are presented in order to provide a better understanding', of the principles involved in alloying steel with HEM. Experimental melts were pro- duced in a 150 ton induction furnace as well as in 25 and 200 ton basic open hearth furnaces. Mishmetal, a rare earth alloy containing 56.1% Ce and 1*1-3% La (other REM, iron, and impurities totaled 2.6%), was used as the deoxidizing agent. Studies were made of both cast and wrought metal states and tables of mechanical properties are in-i uDc: 669.141.243.4 L 45435-66 ACC NR:AP6019765 cluded. The impact strength of steel 40KUHMa,melted in a 25 ton furnace and top- poured at 1580*C, is given. Results of the experiments showed that in all cases the addition of REM increased steel ductility. This increase was greatest when the mish- metal was able to reduce sulfur content in the solidified ingot. Desulfurization wap best accomplished when it was initiated in the ladle prior to pouring into the mold.% Optimum conditions were concluded to be ladle deoxidation and desulfurization by add. ing 0.15-0-20% mishmetal (calculated).to the molten steel (1560-1580'C) immediately '* after tapping from the furnace. The mishmetal reaction begins and most of the sulfur is removed by the time the steel is poured and solidified. The procedure lowers the sulfur content 25 to 30%. The mishmetal significantly reduces nonmetallic inclusion content, as well as changing the shape, composition, and distribution of that content. Finally, the REM alloy increases impact strength of the rolled steel 27 to 47% (transverse test samples) and of cast steel by 47 to 65%, with a simultaneous increase in ductility.

The shank of a .ade workir .A in a variable-pitch propeller encasement was studied as a friction pair. textolitd\S~ushing was used as one member of the pair and the propeller shaft, made of )KhNII4A steel, was used as the other. The shank undergoes periodic reciprocating )tary motion of several centimeters per second. The friction pair is loaded by the !rodynamic fo6c acting on the propeller. The entire friction unit is lubricated Ah MS-20 oil - orrosion ittina was observed on the working surfaces. This type of !ar of the metallic surface is extremely dangerous under variable loads. The ex- -rimental results indicate that corrosion fatigue of the meta 1 in metal-polymer )uplings occurs as a result of condensed humidity in the lubricant. When a polymer Card 1/3 uDc: 620.1 L 40251 ACC NR, Lides against metal, the surface layer is deformed and mechanical failure of certain :)lecular chains takes place. These conditions produce free valence radicals -and icroradicals. This makes it possible for the surface layers of the polymer to enter ito a chemical reaction with the metal. Thus the free radicals stick to the metal irfaces of the shaft. This sets up an electrochemical process which causes increased !ar of the metal surfaces. This phenomenon was verified by subsequent experiments. ie wear of thrust bearings made of Armco iron was studied. These thrust bearings!/ ibbed against circular specimens made of Armco iron and bronze. In one case the )rking surface of the circular specimens had a system of rectangular radially milled -ooves, while in the other case these grooves were filled with various polymer inserts lich covered 30% of the working surface. Tests were carried out in a 0.5% NaCl solu- ~on for 24 hours for each friction pair. A table is given showing the results of irust bearing wear for various specimens at a sliding rate of 14.4 cm/sec and a spe- 'fic pressure of 1.35 kg/cm2. These data show that polymer inserts intensify the Lectrochemical process during decomposition. This causes additional thrust bearing ~ar as compared to the wear of specimens without polymer ~Ilserts.

This problem is complicated by the need to reduce dimensi( ns to a minimum. In this connect- ion, the authors investigated the possibility of developing materials for friction couples of this kind, operating under conditions of dry and liquid friction as elements of a freigbt-transport- ing'monorail-type mechanism. The tests were carried out in a special rig on using rollers of 45, mm diameter with a rotational speed of 100 r. p. m. During the tests the system was gradu- 1/3 A AC~ NRt AP6023451 a4y loaded until its rated load was reached, and the cohesive force and friction coefficients wide determined4or various loads in various media.

For the purpose of irrigating thi area, it has been.proposed to use the wheeled sprinkler pipeline,-type KDT-25. The essential features of this sprinkler are.*.1) It can be-operated from a closed irri- gation net, but, if a transportable pumping station is available,-the-sprinkler.can work.also from an open net of canals; 2) Because it-is self-propelled, the use of it eliminates-the carrying by hand of irrigation pipes from one place to another, which takes 30 to 40 minutes. The wheeled.sprinkler.saves time and saves labor. The wheeled sprinkler consists essentially of rbe following parts: the operating pipeline, t1he driving vehicle, the Card 1/3 supporting wheels and the auxiliary water-conducting
