Therefore, a method for making such rings by electroslag -welding has been developed and introduced into practice. According to this method the ring is assembled from several forged or rolled segments which are bent to a required radius. A mold is built around each joint. The welding is done with a flat electrode and a calcium fluoride-calcium oxide flux. With careful assembly the deformations can be kept to a minimum. The method can be used for rings of any diameter and cross section. Rings ofthe same diameter can be put on top of each other and ~,fflded as a single ring. The method has been successfully used in welding MANIORteel rings 3000 and 900 mm in diameter with respective cross sections of 195 x 195 and 60 x 110 mm, and Khl8NlOT Ateel rings with cross sections of 220 x 220 and UDC: 621-791-793:669-15-194 Card 1/2 -PMU "l-L.B."

Automatic Coubustion- Control System Operating on the Rate of Variations of the Controlled Parameter 3 The author's nodification of an ordinary control system is based on the use of double-acting regulators of the Pblzunov type,, intended for 136sitive self-balancing processes. It is proven that such systems are also applicable to negative [out-of-balancel processes, which are exxtomatically corrected'so as to regain the proper ratios between the quantities under control. This "flowmatic" type of control operates on the variations in the rate of steam flow from the boiler. Card 2/ 4 Antomatic CoAtrol sov/3856 Sentkin,, V.I.# and V.S.

The VUW, V~zkumn~ U'stav )~iitnictvi Zveleza. (VURZ, Ferrous Metallurgy Research Institute) and the Vftk-P-icke' 'z"elezirny Klementa Gottwalda (Klement Gottwald Vitkovice Iron Works) developed the 174819 17482, and 17483 inexpensive, high~temperatureq austenitic, Mn-Cr steels alloyed with Ti, V . and Mo. This,paper deals especially j~ith suitcble filler metals developed by the VUZ, V~zkumn~ fistav zvhracsky (Vfi, Welding Research Institute) in Bratislava, and the long-term strength Card 112 Z/046/61/000/004/004/009 Long-term strength properties ... D007/DlO2 properties of welded joints at elevated temperatures. Creep tests to fracture revealed that welded joints of superheater tubes have the same creep strength as the 17482 and 17483 base metals when filler metals MnCrMo(Nb) 17/7 and MnCrV(Nb) 17/10 are used. For welding 17481, 17482, and 17483 austenitic-steel tubes to CSN 15 225 farritic-pearlitic-steel tubes, the VZU ZVIL, Vkzkumnk a zkus~ebny U'stav Z&voduo V.I. Lenina (VZU-ZVIL, Research and Testing Institute of the V.I, Lenin Works) developed a VZU 60 filler metal which contains a maximum of 0.110% C, 0.30% Mn, 0-80% Si, 19% Cr, 1.50/0. Ti, 15.W. Fe, 5.0% W+Mo, O.8W- Al, and balance Ni. It was found that the long-term creep strength of such a weld is determined by the creep strength of the transition zone of the 15 225 ferritic-pearlitic stee; which is approximately 206 lower than the mean creep strength of the base metal in the not-affected zone. Engineer J. Kouckk of the Ferrous Metallurgy Research Institute is the personality mentioned. There are 6 figures, 9 tables and 10 Soviet-bloc references. (Technical Editor.

In both series the rod ;'%-rere austanized at 1 050 to 1 070 0C for I hour, followed by cooling in air.

A process for production of start- ing billets for such tubes is described. Ingots weighing 3850 kg are teemed; they'are passed throu blooming apd billet mill without being reheated. 130 MM cylindrical billets are reduced by machining to 120 mm.and cut into 390 vim long slugs- These are heated to 1150-12000C and pressed in two hydraulic .~presses into hollow pressings to make seamless tubes.

A new technology was developed of' manufacturing semis for the production of seamless tubes. According to this technology, the heats are utilized for teeming roll-mill ingots, type VI A,, weighing about 3 700 kg, which are rolled into blooms-of 130 mm diameter. These are rough-machined and split into blocks which are used for making hollow pressEngs with-a bottom. Seamless tubes are~rolled from these by current methods. On the basis of experience Card 1/2 Z/034/62/ooo/oo4/oO3/005 Mastering'the manufacture .... E073/E335 gained during development of this inethod of manufacture, detailed technological specifications were worked out for the manufacture of both steels in electric-are furnaces, for the rolling of ingots into blooms, for,the rough-machining and cutting of blooms, pressing the hollow presslings and tho manufacture of seamless tubes. The further part of the concluding report contains results of metallographic and mechanical tests, including creep-fracture testsby means of which the mechanical values for both these steels, given in the works standards,of VZKG (material-property sheets), were verified.

The development of austenitic ec~onomy steels began in Czechoslovakia in the Vitkovice Steel Works -in 194-9. MnCr steels were alloyed with up to 0.25% N and stabilization was effected by means of Nb and Ta. The creep strength at 650-700 00 practically equalled that of austenitic Cr-Ni (Ta, Nb) 16/13 steel, Due to the great shortage of Ta and Nb in Czechoslovakia, further research work was carried..out fordeveloping titanium stabilized Mn-Cr steels, Mn--Cr (Ti) 17/7 (steel 174-81 Card of the Czechoslovakian standard specification). The 115 heat conductivity of this steel is about 22 kcal/m OG hour in the temperature range 300-550 OC, which is considerable compared to the published values Ifor.. 67012 CZECH/34-59-10-7/25 Development of Austenitic High-temperature and Stainless Cr-Mn Economy Steels for the Manufacture of Seamless Tubes austenitic steels. According to the test results of B. Prwenosil (Ref 10) this steel resists oxidation in superheated steam of 180 atm up to the temperatures 6lo-630 OC, and up to 660 OC it resists oxidation in a medium consisting of flue gases with a low content of Sulphur and a relatively high content of water vapour. According to the results of Prenosil and the author of this paper, in the air the steel resists oxidation up to 740-800 OC. In Fig 2 the creep strength of this steel is plotted for durations of 10 000, 25 000 and 100 000 hours. For temperatures above 620 OC and durations exceeding 100 000 hours the values are extrapolated by means of the Larson-Miller parameter. This Mn-Cr (Ti) 17/7 steel is suitable for tubes in forgings intended to Card operate at a maximum temperature of 620 OC, i.e. for 2/5 superheated tubes (560 OC) up to 180 atm. For higher steam parameters a.further austenitic high-temperature Mn-Cr-V'17/10 economy steel was aeveloped; the Pilot plant development of this steel was carried out in the Witkovice Steel Works in cooperation with the 67012 CZECH/34-59-10-7/25 Development of Austenitic High-temperature and Stainless Gr-Mn Economy Steels for the Manufacture of Seamless Tubes Ferrous Metallurgy Research Institute. This steel contains about 0.10% C, 1.8% Mn, 10% Gr, o.6o% v. It has stable austenit-ic structure in the temperature range of technological processing as well as in the range of operating temperatures under consideration. According to the test results of B. Prenosil, the Mn-Cr-V 17/10 steel withstands oxidation under the effect of steam superheated to 700 OC (180 atm); inside combustion products with a high content of water vapour it withstands oxidation up to 7500C' and in air it restricts oxidation even above 750 OC. The bigb temperature stability of the Yin-Cr-V steel was determined by long-run creep tests until failure at 650, 700 and 750 OG for a laboratory 100 kg melt produced in a h.f. furnace, two pilot plant electric~ are melts weighing 0.5 tons and one electric aro melt weighing )+ ton&. The longest test so far (5 kg/mm2, 700 OC) was carried out for a duration of two years and Card one month; the obtained results are graphed in Fig 33 3/5 p 862. On the basis of these results creep strength data as a function of temperature for 10 000~ 2 and . .5000 100 000 hours are graphed d7a Fig 1+,, This economy 67012 CZECH/31+-59-10-7/25 Development of Austenitic High-temperature and Stainless C'r-Mn Economy Steels for the Manufacture of Seamless Tubes austenitic steel has a very high ductility under creep conditions, it has very high values of extension and contraction during fracture and these values drop little with increasing times to failure. It was established that this steel is suitable for forgings and tubes intended to operate at material temperatures up to 675 OC, i.e. for superheater tubes of high parameter steam of 600-625 OC. In the graph of Fig 5 the properties of the here-described economy steels with austenitic Cr-Ni steels are compared. As regards creep strength the Czech Mn-Cr-V 17/10 steel is equal to the American steel AISI 347 or 348. In the Research Institute for Shaping Metals in Zwickan (East Germany) the possibility has been confirmed of producing seamless tubes from the Mn-Cr.-V 17/10 steel by extrusion in the hot state.

Engineer Doctor TITLE: Development of Low Cost Austenitic Creep Resisting Steels in Czechoslovakia PERIODICAL: Hutnick/e listy, 1959, Nr 12, pp 1121-1123 ABSTRACT: Paper presented at the "Symposium on Problems of of Creep-Resisting Materials", 316ske" Lazne, September 11-13, Section III. 1959. Since 1949 the research and development of austenitic creep resisting steel in Czechoslovakia covered not only Cr-N! steels but also N! free Cr-Mn steels. In the case of the latter type of steel the aim was to balance the content of chromium and other ferrite forming elements with,the manganese content so as to obtain a stable austenitic structure, both at operating and at annealing and hot working temperatures and to eliminate the 0 tendency to formation of a-phasef6-ferrite. Up to now the following steels of this type have been developed: manganese-chromium-nitrogen (-tantalumrniobium) 17/10 (N 7430); manganese-chromium (-titanium) 17/7 (CSN 17481); manganese-chromium-vanadium 17/10; manganese-chromium- Card 1/3 molybdenum-vanadium 17/7, The compositions of these steel's 67102 CZECH/34-59-12-25/44 Development of Low Cost Austenitic Creep Resisting Steele in Czechoslovakia are entered in Table 1, p 1121. Oxidation and corrosion tests in atmospheres of air, combustion gazes and superheated steam have shown that the growth of oxide layers on austenitic Fe-Cr-Mn-base steels obeys essentially the parabolic law. However, the temperature dependence of the oxidation rate differs from that of chromium and Cr-Ni steels and is characterized by a sharp rise which sets in from a certain "critical" temperature onwards, which depends on the compositionoof the steel and the oxidation medium. The creep resistance has been determined on laboratory, pilot plant and full scale production melts for test durations up to 20 000 hours, which have been extrapolated to 100 000 hours by means of the Larson-Muller parameter using constant C values,which were calculated for each type of steel. The production technology has been developed and tested on a full production scale for seamless tubes. Argon arc welding of superheater tubes using Mn-Cr-Mo (nioblum) 17/7 filler material has been developed and is being used under shop Card 2/3 and erection conditions for the Mn-Cr (Ti) 17/7 steel.
