TITLE: Design Deficiences of Are Furnaces of theziCB Type.
(Konstruktivnye Nedostatki Dugovykh Pechey Serii ACB)
PERIODICAL: Stall, 1957, No.10, pp. 902-904 (USSR).
ABSTRACT: The design of arc furnaces of theaCB series (capacity
up to 30 tons), produced by "Elektropecl!" is outlined
and some of their design features am criticised. -It is
suggested that the segments and the roller tubes of
the furnace body rolling out device should be replaced
by a roll out trolley and to increase the design
reliability of all hydraulic drives. For large furnaces,,
the use of swinging roofs is proposed.

PERIODICAL: Metallurg, 1958, Nr 6, pp 2,0 - 22 (USSR)
ABSTRACT: The authors point out that although laroequantities
of finely ground materials (such as ferrosilicon, coke, hot
top compound) are required for producing quality and high-
quality steels, there is generally insufficient mechanisation
of the preparation of these powders. They list the defects of
most preparation methods and describe several improvements dev-.
eloped and introdw3ed at the "Dneprospetsstall" Works. One is
a special drum for crushin
,g ferrosilicon (Figure 1) which can
deal with 0.5 t/h. Thedrum consists of two end plates mounted
on a driven shaft and connected peripherally to each other with
square, manganese-steel bars, the whole being hermetically
enclosed in a casing. The drum discharges through a.screen
(Figure 3) into a box (Figure 2); oversize is returned in
another box. The authors state that similar equipment with
balls can be used for coke and charcoal. For preparing hot-
top compound, a special mixer has been provided (Figure 4):into

which J_s trana~ported by narrow-gauge track to a special bunker
in the cast-ing bay. On the basis of experience at "Dnepro-
spetsstail", the authors conclude that crusher-roll mills are
particularly urdesirable. They suggest that for automation to
be introduced, all equipment for preparing the powders should be
concentrated and that automatic weighing of hot-top mixture
components and,special feeders for supplying material from the
bunikers to the crushing equipment should be developed.

ABSTRACT: An analysis is reported of the operation of 20-40 ton are
furnaces at the "Dneprospetestall" Works with,special
reference to the ratio of the diameter of the molten metal
surface to its depth. The main conclusions drawn are that
it is not rational to increase productivity by overloading
(increasing the charge weight over the rated value) by
over 30% for a value of the,ratio of 6.6; construction of
furnaces with ratios over 5.35 leads to incorrect crane-
capacity and incomplete furnace utilisation;, the correct
way of increasing productivity is by improving the power

AB&MCM The article opens with a general discussion of'venaltivity and
operating speed of control systems in relation to electric furnaces.
In large furnaces, although the electrodes and their holders are
usually.massivop the kinetic energy of the motor rotor to usually
wn-A greater than that of the eloctr~:de and elootrode drive miehan-lim'a
Therefore, it is not necessarily possible -to increase the sensitivity
of the system by increasing -the power of the motor. Very often
improvements in mechanical design of the drive will ac-hieve mers.
Experimental studies were made ofthe rope-driTen elettrode drive on
a 40-ton furnacei to investigate -the influenoe of backlash and
clearances in the meshanism on the sensitivity and speed of can-trol
of are furnaces.. The experimental installationja illustrated
schematically in Fig.l.. Thebacklash and electrode dieplacement were
determined by selsyns working under transformer conditions.-

Member ~"""_of AS Ukr SSR, at the Chair of Automation at DMe tI.
Investigation of relay-contact control systems of electric
furnaces proved that the current intensity varied periodical-
ly and that self_oscillating~processes took place due to gaps
and to elasticity of connections in the electrode-shifting
mechanism. The electro-mechanical control system was also
investigated, and the analysis of oscillograma has shown that
it has a series of advantages. Certain advantages,ofthe
electro-mechanical control system can.only be-utilized in the
case of an improved design of,the electrode-shifting mechanism.
The author recommends the employment of an,alectro-hydraulic
servo-mechanism'and the highly-sensitive and high-speed
hydraulic control system., Blectro-hydraulic drive of else-
trode shifting with electro-mechanical control ensure stable
and accurate automatic control and proved more satisfactory,
than electro-mechanical drive with the same control system.

Stall, 19599 Nr 6, pp 5~6-531 (USSR)
Soviet specialists developed satisfactory automatic
power regulation circuits for arc furnaces (Ref 1, 2)
but they paid insufficient attentiozi to improving the:,
design of execution mechanisms, whichwould enable full.:,
utilisation of the potentialities of these circuits.
In this paper,the technique and results of experimental-.-
investigations are described of a system of automatic
regulation of a 40-ton steel smelting; furnace-aind'
methods of improving the design of the execution
mechanism are outlined. Theauthor proposes using a
hydraulic servo mechanism. Unlike the Ide'sign of
Whiting (Ref 3,and 4), which is,fitted with a single
pump, this servo system is fitted with two pumps.
The following conclusions are arrived at.-
1) it is.essential to exclude entirely, or to reduce to

play is eight to ten times larger than that caused by
the insensitivity and inertia of the electric circuit
of the relay-contact regulators.
2) The connection between the electrode holders and the7.-:
motor must be as rigid as possible in order to increase
the efficiency of the.execution mechanism and to
improve thequality of the automatic regulation.
3) The author considers It important todevelop and
introduce in Soviet electric furnaces regulators with
hydraulic execution mechanisms. There ate 7 figures

ting the furnace, rotating the bath and turning the vault and.all gear
racks of the DSP-80 type furnace tilting mechanisms which are connected in
the old types with one common transmission shaft, have here separate drive&
and consequently there are fewer brbakdowns, The removal of the slag was
solved in a satisfactory manner Special features of the mechanism for ro -
tating the bath are two non-seli-locking drives, open pedestals and support-
ing rolls with antifriction bearings instead of the conventional friction
type bearings. Heeeby the power consumption of.the driving motors was re-
duced and breakdowns occuning in the conventional type eliminated. A weak
point of the unit is the electrode control gear in the operation of which a
delay can be observed due to the elastic deformation of the steel wire and
a play in the transmission and a considerable statical moment of the motor
when lifting the electrode caused by the unbalanced progressively moving
parts (of a weight of about 4.5 tons). The drawbacks could be eliminated
by substituting the electromechanical system for an electrohydraulic
tem. There are 4 figures, 1 set of figures and I table.

TEXT: The decisive effect of lagging in the various transmission links Of
auto.-:,atic electrode feeding mechanisms is proven. Such lagging in automatic con-,
trol systems of other metallurgical machines is mentioned with reference to a.
work by S.N. Kozhevnikov (Ref. 1) who cited examples illustrating that even the
most sensitive wid precise control systems have no effect when the work mechardsms
are not accurate. It is mentioned that Tsentral'naya laboratoriya avtomatiki En-
ergochermata (The Central Automation Laboratory of Energochermet) has completed
the development of a fine automatic electrode control system for are furnaces, in-
eluding an electronic computer, which is another example of useless precision In
the electric control system because of a crude work mechanism with gaps and flex-
ible links. Various existing automatic centrol system designs are analyzed using

the approximate analysis method with simplified block diagrams of A. Lang (Ref.
2) (A. Lang, "Regelungstechnik"j 1957, PP. 117 122). A general block diagram
for all systems is used (Fig. 1) and simplified more, into an equivalent diagram
(Fig. 2), and calculations are made using experimentally determined characteris-
tics of separate links in different systems and values of A. Lang. Curves are
plotted illustrating that it is theoretically,impossible to achieve any consider-
able increase in the electrodes feed when gaps and flexibility are,present in the
work mechanisms. The results of calculations show that the electrodes feed speed
could be increased 3 - 5 times if the lags in the transmission system were elimi-
nated. The following conclusions are madet 1) The most important trend in im-
provement of automatic regulation is reducing of the lag, i.e., design improve-
ment in the work mechanisms, and choice of the proper drive., 2) The experience
and the calculations prove that even'in the latest furnaces with rack transmis-
sion a lag of 100 m - see has to be taken into account. A complete elimination
of gaps and flexibility in the links would result in the increased speed of the
electrodes displacement (it would be trebled in the case of A magnetic and an
electro-mechanical regulator). 3) The application of sensitive (inertla-free)

combination with imperfect work mechanism designs'(e.g.,, with rope drive), for
the practical effect will be negligible.
In the.development of new automatl
regulation systems and modernization of those already existing, systems fully
eliminating delays from gaps and flexibility as well as systems eliminating the
Ieffect of inertia are of high practical interest. One example of a system nearly,
fully eliminating lags is a hydraulic system with two pumps - one pump evacua ins.,

TITLE. Formation and elimination of cracks in steel castings.
PERIODICAL: Liteynoye proizvodstvo, no. 4, 1962, 31 - 33
TEXT. The authors point out that the main defects of steel ingots are
longitudinal and transverse cracks. Among -the ?orces affecting the formation of
cracks, the authors mention in the first place the force originating owing to a
deceleration of shrinkage of the primary skin. They present formulae for calcu-
lating the stresses originating In the ingot skin for the cases of a uniform and
nonuniform skin thickness and stress the point that the quantity of sulfur and
hydrogen impurities in the steel affect the tendency of steel to hot-crack fo
tion to a considerable extent. It is stated that large additions of aluminum 10--
calize the harmful effects of sulfur. Apart from the effect od the modulus of
elasticity, the steel-composition affects the magnitude of the coefficient of 1i-1.

fore, steel with a C-content of some 0.2% possesses the greatest tendency to
crack formation. It is stated that a nonuniform formation of the clearance be-

tween the crystallizing ingot and the mold and the washing away of the crystal-
lizing skin by the circulating Row of liquid steel contributes to,a local thin-.
ning of the skin and thereby to the formation of cracks. It was.found that the
clearance between ingot and mold is formed in the first place at the ingot corn--
ers and, to eliminate corner cracks, the rou~ding-off radius at the ingot corners
should Amount to 0.1 of the length of the shorter ingot side,.or less. According
to data obtained by G.P. Ivantsov the heat-transfer coefficient from the ingot to,-,--

the mold decreases by a fa tor of 4 - 5 after
After the complete or partial separation of the ingot from the mold walls,~ the
destroying action of the hydrostatic pressureforce of the liquid metal of the
ingot core affects the skin of the solidifying metal. Calculations have revealed,_
that the magnitude of bending moments arising under the effect of hydrostatic
pressure forces are the lower, the more points of the ingot skin are pressed
against the mold wall. The authors point out that, to create favorable condi-
.tions for the crystallization and shrinkage of the ingot, the inner surface
ingot mold should have a wavy profile. They present details on the most expedi-
ent wave shape and state that the most dangerous stresses depend on the cooling
intensity of the ingot surface. The use of heat-insulatiLng coatings.of the. mold
makes it possible to reduce the cooling intensity of the ingot surface by a fac-

uults were obtained witbi a coating consisting of 43% red clay, 26% refractory

clay, 6% fluorspar and 25% lime. The authors comment on the hydrodynamics of
steel pouring, mold design and steel shrinkage conditions in the mold, factors
that affect the ingot surface quality to a great extent. It is pointed out that
the best ingot surface is obtained with a total casting duration of theIingot

front of the crystallizing metal determines to a considerable extent thethick-
ness of the crystallizing skin. Concluding, the-authors empliasize that in the.
production of large-size ingots, top casting is to be preferred to bottom cast-
ing.

TITLE- An Apparatus for Measuring and Recording the Resistance of

TEXT: Usually, the conductivity of aLS'Mia measured by a
e onductor is
compensation method, and results are shown as curves logd --' f(l/T) on a
graph- This method has a number of inaccuracies and sources of error
which are discussed in the introduction. The.authors have developed an
instrument (whose block diagram is shown in Fig. 1)~ which consists
essentially of a combination of a logarithmic and a hyperbolic amplifier,
and allows the curve log R f(l/T) to be recorded directly, without the
disadvantages of the earlier methods. The apparatus works as follows:
When a semiconductor is placed in the field of an alternating current of
constant magnitude (originating from a sound generator of the type 3P-10
(ZG-10)), the potential appearing on the probe of the semiconductor is

~proportional to the resistance of the latter. The logarithm of.this
potentialis taken by the logarithmic amplifier, and recorded by an
automatic electronic potentiometer of the type grin-09 (EPP-09) (or, even
better, by a two-coordinate recording instrument). The function
M log R = f(N/T) is recorded on the band of the apparatus, the coefficient
M depending on the dimensions of the sample, and N onthe thermocouple.
N is determined from the characteristics of the hyperbolic amplifier. The
theory of determination of the temperature dependence of the conductivity
of semiconductors is discussed at first. Later, the logarithmic amplifier
(Fig. 2 shows the dxact connections), and the hyperbolic amplifier
(Fig. 3 connections, Fig. 4 calibration curve) are described in detail.
Finally, the measurement of a high-resistance sample is described. The
apparatus was tested on samples of Ge, Te, Si, and other elements.
Fig. 6 shows the curves of some measurementson Ge, Te, and.Si. The
values obtained are for Ge: AEO 0-78 ev, and for, Te: Mo = 0.4 av.

Menological formula for the coefficient of thermal conductivity of
a semiconductor, K = CvX/e (C -- heat capacity, v -- electron velo-
city, X -- electron free path), and demonstrates that the bulk of
the heat is transported by the drifting electrons and that applica-
tion of an electric field can either increase or decrease the elec-
tron drift. Here Ithe remaining symbols are standard. If the elec-
tric current and Me heat flux flow in the same direction, the
thermal conductivity decreases, vice versa. It is further shown
that zero heat flux cannot be obtained in principle, owing to the
