ABSTRACT: This Author Certificate presents a remote anemorhumbograph containing a
wind sensor in the form of a four-bladed propeller fastened to the front part of a
drop-shaped hull with an emponnage as a wind vane..a tachometer.-generator., and two
selayn-detectors (see Fig. 1).. To record the averago and instantaneous wind velocity
an a common~scale of the recorder tape, the wind senaor shaft in coupled to the
tachometer-generator using Wnrel gears and to the selsyn-detector through a reductor.
The number of revolutions of the wind sensor during a given timo interval is trans-
formed into the angular displacement of the selsyn rotor. To record the instantaneous
wind velocity as the total v(x1ocity prof:Lle or as tho excess avor the average wind
velocity., the average wind vcaocity recorder carriago is provided with a switching
pin which lifts the pen with its passage through the average velocity line or limits

TITLE: An Improvement in the Regulation of Electrical and Thermal Conditions in

ABSTRACT: Electric parameters and regimes of arc steel-melting furnaces intro-
duced ten to fifteen years ago were largely determined by the level of automatic-
control art at that time. To meet modern needs, a type AR electromagnetic
regulator was developed in 1949, and an improved type RMD regulator was de-
veloped in 1952, which allow operating the furnaces under more productive and
economical conditions. The use of new regulators permits reconsidering the
electrical parameters and regimes of existing furnaces. The most important
productivity reserve of existing furnaces and reduction of per-unit power

consumption are associated with introduction of higher-capacity transformers
and with stepping up voltages at the moment the metal is actuaLly melting. To
measure the temperature value closest to its mean value, the -measurements
should be made at a considerable depth in the bath (at present, the measure-
ments are taken 100-200 mm from the surface), where the temperature gradi-
ent is relatively small and where the temperature is less dependent on the ef -
fects of chance momentary factors. For improving regulation of the electrical
and thermal regimes of electric-arc steel-melting furnaces, the following steps
should be taken: (1) At each plant, and for each brand of steel, the relation--
ship between the metal quality and its temperature (in the ladle) should be de-
termined, by checking steel temperatures in the ladle. (2) The practice of
measuring metal temperature during melting should be widely adopted.
(3) The plants should be supplied with standard tungsten and molybdenum wires,
thermocouple mountings, and electronic equipment for making these tempera-
ture measurements. (4) The furnace temperature fields should be studied to
determine the measurement points that provide the best approximation of the

ABSTRACT: The electrical characterigtics of'operation of a 20-ton
furnace during 10 heats is plotted in Fig.1, p.602. Analysis
of the respective data indicates that the r.m.s. values of the
phase current intensities vary between 8? and 121% of the
nominal value,equalling 16 500 A, and there are also extensive
fluctuations in the ratios of the phase currents between one
heat and the next; the difference of the average (1 hour)
values of the phase currents may reach 30%. The fluctuations
of the total useful energy introduced in the furnace during
the individual heats may amount to 21% of the basic value
assumed at 5 400 M The fluctuations of the average, useful
electric power from one heat to another amount to + 15to 20016
of the basic value of 1 800 kW and the differences in the use-
ful power of the individual phases may reach 3001o. The fluct-
uations of the average values of the power factor for the various
heats reached 0.042%. Analogous results were obtained on
another 20-ton capacity arc furnace. Application of automated
TsLA analogues (developed according to the theoretical circuit

has enabled,for the first time, the control of the total values
of the active and the reactive resistances of the sections of
the short network located outside the furnace for a 20-ton
furnace and, thereby, the control of the total reactance of
each phase and the measurement of the voltage of each are. By
means of these devices, it is possible to determine periodically,
in accordance with the progress of the smelting, the total
ohmic resistance of the phases and the differences in the mutual
inductance coefficients of the phases which characterise the
possible electro-magnetic power transmission. The results of
numerous measurements obtained during 10 heats enabled the
elucidation of the importance of the above mentioned parameters
and the possible ranges of their variation. The results show
that the parameters of the short network outside the arc furnaces,
the electric losses and the useful electric power of the
individual phases change continuously and appreciably, both from
one heat to the next and during each heat. Therefore, use of a
continuous or periodic verification of these values during the
smelting cycle enables better control of processes involved

increases in electric power. The developed mechanisms for

permits changing over to automatic control of the electric
energy fed in to the furnaces during the smelting. The problem
can be solved, for instance, by introducing into existing electro-

ABSTRACT: The temperature range within the bath of an electric steel
foundry furnace may attain 40 or 500C. Investigations con-
ducted by the TsLA and the Elektrostal' Plant, in which 5- and
15-t furnaces are used, confirm the existence of a tempera-
ture gradient attaining 1.5 degree/cm. Rabbling reduces but
does not eliminate the temperature differences. Improved ac-
curacy in temperature measurement may be accomplished by
refinement of the measuring devices and primarily by equal-
izing the temperature field of the bath, e.g., by the introduc-
tion of magnetic agitation. An experimental installation for the
measurement of temperature that has been mounted on a *5-t

ABSTRACT: Electromagnetic transfer of power from phase to phase,
continuous and significant change in network voltage, secondary-
circuit parameters, electric power losses, etc., during a heat
and from heat to heat are the reasons for the unsatisfactory
operation of all regulators having the purpose of providing
specified amounts of power to the arc, as the available electric
power varies approximately as the square of the relative mag-
nitude of the line voltage, i.e., quite significantly. Tests of an
amplidyne control with an electromechanical integrating unit
and of a regulator with electronic computing attachment show

ABSTRACT: Owing to the fact that-in a Bteelrarc -furnace the electroma.-net.-
ic conditions are unsymmetrical and the leads have differ,~!nt
lengthe, the inductivities of the three phases differ o-ins'Mer-
ably. Hence it would be desirable to operate furnaces with ou~r-
rents, voltages, and powers, which, even if not being absnJatsly
equal, differ only little. For this purpose, methods must be
developed which permit: (1) to calculate the perforzance of the
arc-furnace for arbitrary values and ratioa of the voltagaq
across the arc, the currents, and the effective power consumptions
of the phases. (2) It must be possible for the given economical
system to select a limited number of oombinationa from a'wide
variety of such combinations of currents, voltages, and power
consumptions of the phases which at different inequalities be-
tween the are voltages and phase currents secure sufficiently

requirements,of furnace operation-This paper gives the solu-

sinusoidal arc voltage is investigAted. A mathematical model is
described which permits a,solution,of very complicated problems
and an investigation of arc-furnace performancef considering
the'distinctly marked non-li4earity of the are resistances for
given effective phase powers, phaie',currents, and voltages. This
model was developed by the author together with V. V. Stepanenko,
V, G. Sirotkin, and E. G. Uderman. The principal circuit diagram
for simulating the non-sinusoidal are voltage is shown by fig-,
ure 2. The external current-versus voltage curve of the arc is
presented by figure 3- Figure 4 contains the circuit diagram of
the model. The conditions of -power distribution between the
furnace phases are investigated, and conclusions are drawn here-
from. The model described in this paper was used to test the

TEXT: Work on complex automatic control systems of are furnace
steel smelting started in the USSR in 1956. In the present paper
the author describes several new devices for the control, regula-
tion and analysis of the main technological parameters. The descrip-
tion and discussion of operation of some of the following is given:
A mechanized mathematical analogue for telemetering of resistive
and reactive resistances, voltages and powers of the arcs; a com-

optimum electrode spacing; a mathematical analogue for analysis of
the electric states of are furnaces with electromagnetic asymmetri-
cal current supply and the effect of non-sinueoidal arcs; thermo-
couples for measuring the lining temperature; the arrangement for
measurement and control of introduced oxygen; device for measur-
ing the thermal lopsesl the digital computer arrangement for re-
gistering several process parameters. The use of the new control
devices in are furnaces made it possible to obtain in 1959 the fol-
lowing results: in 55% of smelting processes the required changes
in the metal temperature were kept within + 200C. Deviation of the
metal temperature in the ladle from the opTimum -value was reduced
by approximately 4 factor of two; duration qf smelting was reduced
by 6 - 10%; the average power requirement was reduced by 7%; the
quality of the steel was improved. A new prototype of a fully auto-
matic arc furnace, with a new triple-bifilar construction of power
supply circuit, is being designed. There are 8 figures and 2 So-
viet-bloc references.

PERIODICAL: Ogneupory, no- 4, 1961, 181-184
TEXT: The authors describe thermocouples with refractory endpieces for
measuring the temperature of liquid steel and of the refractory lining.
The Tsentrallnaya laboratoriya. avtomatiki (TsLA) (Central Laboratory of
Automation) and the zavod "Elektrostall" (Works "Elektrostall") are
conducting comprehensive work for the automation of the steel melting
process in electric arc furnaces. The following persons participate in
this work: L. V. Vinogradova, N. I. Voronin, L. I. Gellis, I. A. Getman,
V. V. Levchuk, T. Z. Malikova, 0. M. Margulis, K. G. Romanchenko, and
D. S. Rutman. Fig. 1 shows the arrangement of the thermocouples for
continuous temperature measurement of the lining as well as of the

liquid steel temperature in the electric arc furnace. Thermocouples
with tungsten-rhenium electrodes with a content of 5/1 and 2TIo of
rhenium SP5/20 (VR5/20) which had been developed by the TsLA and the
Moskovskiy elektrolampovyy zavod (Moscow Incandescent Lamps Factory)
and tungsten-molybdenum electrodes with an addition of 0.5% aluminum,
which were produced by the TsNIIChM (Tsentrallnyy nauchno-issledovatel-skiy
institut chernoy metallurgii (Central Scientific Research Institute of
Ferrous Metallurgy)) proved to be the most stable thermocouples for a
continuous temperature control. The temperature of the lining is
continuously recorded by a self-recording potentiometer. To select the
most suitable endpieces the products obtained from ZrO29 A1203 ' Beo' MgO
were tested which had been produced by the VIO, UNIIO (Ukrainskiy
nauchno-issledovatel~skiy institut ogneuporov (Ukraine Scientific
Research Institute of Refractories)) as well as by the Podollskiy zavod
(Podollsk Works). The experiments were made in a 20-t furnace operating
with a 9000-kva transformer. Maximum stability was observed in high-
alumina endpieces which had been produced by the Podol'sk Works of
Refractories. The experimental results showed that endpieces with a wall

thickness of more than 1.0 mm, are suited beat for the continuous
temperature measurement of the lining of walls and area during 4-5 hours
(duration of melt) (Fig- 4). Endpieces with higher thermal stability
are necessary for temperatures*exceeding 17000C. The duration of melting
and.thus also the overheating of the lining can be reduced by increasing
the temperatures of the metal in the period of oxidation. Test malts of
remolten UJ1,15 (ShKh15) steel showed that with a reduction of the
specific current conaumption bY 50-55 kwh on the average, tho average
duration of melt could be reduced bY 33 and/or 17 min. The control of
electrical and thermal conditions resulted in an increase of the average
stability of walls and arcs of electric arc furnaces by approximately
3-5 melts. There are 4 figures, 2 tables, and 4 Soviet-bloc references.

TEXT: The author considers experimental methods which, given ex-
isting control arrangements of stationary technological processes,
will permit determination of the maximum improvements in the tech-
nical and economical aspects of production by improving the automa-
tic controller, by introducing devices for automatic control by
stochastically varying the uncontrollable, but measurable quantity
and by choosing the optimum regime of the controller. The analysis
is limited to stationary, random processes, in which only one phy-
sical quantity is characterized by stochastic changes, since the
changes in other quantities are not in practice reflected in the
technical and economical indices of production. The following

problems are considered: a) Increasing output; b) achieving econo-
mics in raw materials; fuel, power, etc.; c) lowering the cost of
the finished product unit. To do so, the idea of an ideal automa-
tic controller (AC) is introduced, which has the same meaning as
e.g. introducing 100% efficiency. The AC compensates for the de-
viations of the stochastic cluantity x from its value for the best
required production index J(x). From experimental evaluation of the
probability distribution function W(x), the mathematical expectati-

lity index TW. Experimental determination of M[xj , M EV-7 and of
lid'eal in the case when the technical and economic efficiency (TEE)

controlled quantity x, with or without inertia - may be accomplished
in various ways. It may be done experimentally from the knowledge

capital expenditure, required for the impruvements in AC or the au-

Automated control and regulation of heat conditions of a steel-
melting are furnace
Metallurg, no. 6, 1962, 16-18
TEXT: To eliminate deficiencies in the use of immersion thermocouples,
the Central Laboratory of Automation and the Elektrostall Plant have designed
a mechanized unit for multiple periodic measurement of the metal temperature in
the pool of a steelmelting are furnace and have developed-an automatic method of
regulating the heat conditions of the furnace. The temperature-measuring unit
consists,of a pneumatic force-mechanism, a trolley for moving the thermocouple,
guides, a mechanism controlling the position of the thermocouple and a control
board. The unit is fixed to the furnace portal and the tungsten-rhenium thermo-
couple Is introduced into the furnace through a special hole. Between the
measurements, this aperture is closed by a pneumatic-driven.slide which operates
the electro-pneumatic relay circuit of the thermocouple. An electronic potentio-

meter with a signal unit and automatic control of the completed measurement
serves as a secondary registering device. The use of this device reduces errors
in measuring the mean pool temperature; 'the temperature control can also be
performed during smoke formation without switching-off the furnace, The metal
temperature pulse can be used to produce a closed circuit for the automntlc
control of the furnace heat conditions. The metal temperature indicator is
connected to the heat-condition control unit which operates the transformer-
voltage step-switch and an automatic device regulating the power supply with the
aid of a computer. Experiments made with the new and conventional units show
that the temperature straggling of the metal in the pool and in the ladle can
be reduced by a factorlof 2.5 - 3.5. The efficiency of the furnace Is raised
by 7 - 9%; electric-power consumption decreases by 3.5 - 11.0%. There are
