TITLE: Mechanization ofthe Preparation of.Pawdered Materials in the Melting of Electric Steel (Mekhanizatsiya prigotovleniya poroshkovykh materialov pri vyplavke elektrostali) 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 Card 1/2 SOV/130-58-6-9/20 Mechanization of the Preparation of Powdered Materials in the Melting of'Electric Steel which screened and weighed components arb char ed; mixin takes 9 9 15 - 20 min. after which the powder is discharged into a box 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. 1%19re are 4 figures.

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 supply (raising the transformer secondary voltage, improving,, Card 1/2 AUTRORg SapkL, A.I,-(Ugineer) SOV 110-58-10-14/24 JITLEs ProblPmB of improving the design of operating mech&nI-=w for automatic power-tontrol systems on steel-melling,are-furns,ees., (Voproxy uluchsheniya konstruktaii ispolnitel'Inykh sithhanixiaor sistemy avto"ticbeskoge regalirovaniya nombchnosti dugovykh staleplavilInykh peefify) PMIODICALs Vestnik Blek-tropromyAlennosti, 1958,,No.10. ppo W57 (USS) AB&MCM The article opens with a general discussion of'venaltivity and operating speed of control systems in relation to electric furnaces.

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 vault is lifted and turned by in- dependent mechanisms operated electrically. Two gear racks for tilt 'ing the furnace are actuated by electromotors. The furnace shell, the mechanism for turning the portal frame and the mechanism for reversing ~he bath are mounted on the base of the furnace support. The Vault is lifted by a worm wheel reducing gear electrically operated. The vault turns simultaneously with the portal frame mount;d on the base' plate.which is arranged on a ver- tical shaft. This shaft revolves in two radial-spherical bearings of.750mm V/ diameter supported by a self-aligning ball socket. The revolving of the bath around the vertical shaft.covers about 400; the furnace shell is 'sup- ported by four pedestals via an annular rail. Being in operation for one year it was found.that the new type furnace has the following advantages: there is no moving platform with all the necescary mechanisms for lowering9 lifting and travelling.

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.

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) Card 2/5 8/018, S/148/60/000/01 A161/Ao3o iAn Analysis of Automatic Power Regulation-Systems in Are Steel Furnaces and more complex (and less de'pendabie)'el6ctric regulator systems is senseless in 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., and the other forcing the fluid, without reversing the motor for liftin and low 9 [Abstracter's'note-'~ Reference 6 in connection with this Iering the electrode. system is an obvious misprint for only five references are listed at the 'end of the article].

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. near shrinkage, which decreases with an increase of the carbon content. There- 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- Card 1/3 F S/1 28/62/000/004/008/010 Formation and elimination of cracks in ....

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,-,-- C -the formation of the clearance.. 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- Card 2/3 S/1n9/62/C00/Oo1i/oo8/610!

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 'which is approximately equal to the timeof clearance formation in the lower in-~ t.IS got part. The speed and temperature of the eiroulating steel flow along the, 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. Af Card 3/3 ;30V/130-58-.9-9/23 AUTHOR: Sapko, A.

TITLE- An Apparatus for Measuring and Recording the Resistance of Semiconductors in the Coordinates log R f(I/T) PERIODICAL: Fizika tverdogo tela, 1960 Vol. 2, No. 7, PP. 1462-1488 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 Card 1/3 An Apparatus for Measuring and Recording the S/18 60/002/007/015/042 Resistance of Semiconductors in the Coordinates log R f(l/T) ~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. The authors thank V. P. Zhuze, A N. Goldobin, A6 N.
