Abstract : A laboratory method has been developed for the investiga-
tion of the reduction of the oxides taking into account
the filtering effect of the charge in industrial furnaces
using electrodes inserted in the charge. Some information
has been obtained on the reduction of CaO and the mecha-
nism of the reduction process. Most of the CaC2 is formed
in the lower high-temperature zone of the furnace where
the liquid phase collects. An increase in temperature
from 1800 to 19000 increases the conversion to carbide

above 10-30%. The excess C in the top carbonaceQU3
layer of the charge is the product of the dissociation
of CaC2. The C and e1ementary Ca diffuse to the upper
layers of the charge imd cover the surface of the CaO
and C chunks and d:Lff)ise Into the interior of tbp- latter.
SiO2 and its dissociation products are reduced In tkie
vapor state. When sufficient iron filings are added to
the charge to form 45% Fesi, metallic beads are formed,
the carborization of tha Fe being accompanied by its
enrichment in Si in tqe upper layers of the charge at
1-100-12000.

Tubular electrodes used in .... AG,54/AI27
iodical flashes of the are of tubular electrodes are less intensive and less con-
centrated and, therefore, they are less harmful to the furnace lining. The cur-
rent load per phase is more stable, and depending on the phase conditions of the
furnace, increases by an average of 20 - 30%. This can be explaine-a by the arc
burning conditions being improved, due to factors affecting the arc-discharge
stability, which, as time progresses, shows less change than when using conven-
tional electrodes. The number of automatic cut-outs of the oil switch is reduced
by 30%, on account of a stable current load of the transformer rendered possible
by a physical contact between the electrode and the charge. liview of the re-
sults, tubular electrodes are most expediently used in smelting carbon-free ferro-
chrome in refining furnaces. They are expected to contribute to a prolonged ser-
vice life of the furnace lining and due to their electric load stabilizing effect
they will make possible higher voltages in electric steel smelters and ore-smelt-
ers. There are 3 figures.

TITLE: Variation in the maso transfer coefficient for magnesium
vapor condensation from a mixture with helium
PERIODICAL; Akademiya nauk SSSR. Doklady, v. 147, no. 4, 1962, Be6-888
TEXT: The condensation of magnesium vapor-mixed with helium was
determined at atmospheric pressure and at a flow rate of 1 am/uec.
Details of the method used for the purpose will be described in a paper
that is now being printed. In the first series of experiments, the
concentration of-magnesium in the vapor and on the condenser surface
was altered by varying the temperature of.coridensation. In the second
series, only the surface temperature of the condenser was varied, the
initial partial pressure of the magnesium being kept constant. The mass
transfer coefficient was calculated from q - (apAT c ) ln[(p pc)/(p - ~i)19
where a = D/6 cm/~ec; D - diffusion coefficient,3cm2 /see; 6 thickness of
the diffusion layer. The second series showed a to be a linear function
of T.. The results of the-first series indicafe that a probably depends

ABSTRACTs An apparatus for determining the mass transfer coefficient during metal
vapor condensation from a mixture of metal vapor and permanent gas was developed.
A schematic of the apparatus is presented (see Fig. 1)* This apparatus was used for
determining the rate of condensation of magnesium vapors from a helium-magnesium
vapor mixture. The experimental results are shown graphically# 1t was found that
the condensation rate obeyed the Stephan-Maxwoll law* Ye. A. Vetranko participated in

TEXT: A method is given for calculating the stress tensor from data of
seismic observations. To use the conditions of 0. Mohr (Ref 1). the three
components of the stress tensor and the total stress tensor must be known
Formulas are derived for an infinite hcmogeneous, isotropic medium First
the Lame'2constants A andp are determined from the formulas (Ref 5)~

from simpler formulas. When the stresc tensor has been determined, the
stability of the respective structure or massif can be estimated on the
basis of Mohr's stability conditions, The publication of this article was
