ABSTRACT, A description is offered of the results of conversion of three
50-t open beartlis at the "Red October" plant to heating by cold
natural gas (NG) of 8500 kr-al/nm3 heat capacity, carburetted
with heavy oil, with a partial reconstruction of the ports. The
best results are obtained with the VNIIMT internal -blending
burners. The following approximate minimum parameters are
established for the use of NG for low-capacity furnaces: gas at
1-3 atm excess pressure, consumption of heavy oil in the -,as-
and-heavy-oil mixture rV30% of the whole (measured in terms
of heat released), heavy-oil pressure 4-6 atm excess, pressure
of atornizing component (air) 4-6 atm excess when the air used

TITLE: Thermal Insulation of the Crown of a Basic Open-hearth Furn-

PERIODICAL: Tr. Nauchno-tekhn. o-va chernoy metallurgii, 1957, Vol

ABSTRACT: The heat lost through the basic crown of a furnace consti-
tutes about 30% of the total amount of heat which escapes
through the lining of the furnace. Positive results were obtained
in experiments in which the basic crown of a furnace at the
Verkh-Isetskiy plant was thermally insulated. This was ac-
complished by covering 75-80% of the crown surface (made of
Satka brick 380 mrn thick) with light-weight, fireclay brick BL-
1.3. Furnaces with insulated crowns (IC) operated at higher
temperatures. The output increased by 5-6%, while the fuel con-
sumption was reduced by 6-12%. Owing to their greater temp-
erature stability and their decreased tendency to absorb iron
,er than
Card 1/2 oxides on their internal surfaces, the IC's serve long

furnace crowns which have not been insulated. Chipping and peeling oc the
crown brick proceeds more uniformly-, the wear of the c ro-wn during the ex -
periments amounted to 0.42 mm per smelting (as compared to the ave-age
shop value of 0,43 mm). The employment of IC's increases the weldability
of the crown brick.

ABSTRACT: At the end of 1957, two works were operating open-hearth
furnaces on natural gas with a pressure of I and 10 atm.,
respectively. The investigation carried out by VNII14T
on these furnaces indicated that the gas pressure, tile
nature and pressure of tho atomising medium, the rato of
consumption of the carb%irising medium and some other
factors have a considerable influence on tile efficiency
of utilisation of natural gas as an open-hearth fuel.
When the Libknekht Works start,.~d operation on natural gas,
its pressure was fired at 2.5 - 3.0 atm. A study of the
thermal operating conditions of a 185-ton furnace with
air or steam as atomising agents for the carburising oil
(up to 3090') was carried out. For comparison a preliminary
investigation of the furnace operation when fired with
Cardl/3 fuel oil was made. Characteri3tic features of furnace

It vreAs found that on from oil to natural-gas
firing, the produ,:ttivity of the furnace did not decrease
and the, consumption of s-.;L-_#,what decreased. In view
of a shrong influence of rate of consumption and
pressure of the atomising agent on radiation characteristics
of the flame, the determination of rational values for the
above parameters is necessary in each individual case.
On transferring furnaces to natural-gas firing, the above

A&3IT,UACT: Series capacitors in transmission lines Ilave discharg~rs
to protect them from overvoltages when short circuits occur
on the lines. Die capacitors are provided witha shunting
circuit breaker intended for operational sxitchin:nand for
disconnecting the inetallation for repair or examamation. The
operating conditions of these circuit breakers have certain
special features. The class of insulation can be lower than
that of the rest of the syt3tem if the breakers are installed
on an insulated platform. The rupturing capacity is not very
great as the-greatest current to be disconnected is the line
current in normal overload conditions with a low rate of rise
of restriking voltage because of the lar,--- capacitance in
parallel with the contacts. There are certain additional

-nd dynamic effects of the disch-arge currents. Howeverl tests
carried out with circuit breakers types BBU-110 and BM-35 on
a 220 kV installation show that no damage was done to current
carrying parts by electro-dynamic forces after multiple pass-

age of discharge currents the amplitude of which was much
greater than the normal permissAle maximum short circuit
current. Tests that were carried out arc described and thc-
results are given in the form of oscillograms. It was found
that the de-ion grids took no part in the process of arc
suppression and may be removed whilst the contact system
must be made in such a way that rigidly mounted iJarts are not
in the way of the explosion wave. The contact system was
accordingly reconstructed and the way in which this was done
is illustrated. Because of removal of potential screens the
discharge volta&e between budings and tank. was reduced by
10 - 15 kV.
Apart from the danger of dynamic effects of the explosion
wave on the contact system the-quantity of enerey dissipated
in the breaker after a large number of repeated discharges
of the condenser battery may greatly exceed the energy dissi-

oil deterioration products is high; the oil had to be changed
after shuntino a few times a 220kV condenser installation with
a line current of 600 A equal to the rated current of the
breaker. Contamination of the oil was insignificant at currents
up to 450 A. This contamimation can be reduced by increaAnG
the speed of separation of the contacts and increasing the
damping resist4ces in the breaker circuits. It viould be
advisable to develop circuit breakers of light construction
specially intended for opciution in series capacitor install-
ations. Circuit breaker BM-35 cannot be used without recon-
struction of its contact system.

The absorption of light in a heterogeneous medium may be
represented by E = -k(r)Edr = -:- Vtq(r)Edr.
where E is the intensity, k(r) the coefficient of abso tin,
"Tr).
and A the coefficient of absor , I
.ption per unit density
In practice the full photographic absorption is studied so
that k (r) may be taken as independent of wavelength X and
equal to some mean value in the given spectral region. If
the distribution of matter is studied over extended regions of
space X may be taken as independent of r. which will be
approximately true in the Galaxy. Hence,

To determine the density distribution of absorbing matter

The data of VanRhijn were used in constructing Table 2
and Fig-3- Column headings are the same as for Table I and
Fig.1 respectively. VanRhijnls data are the more reliable.
From these graphs the following mean distribution of
density along the z axis was obtained.
()A5)z = DZ = 24.38 - 10 -4 exp 216.5z� 0.68
Assuming circular symmetry, the radial distribution was
found to be DR = 19.28 x 10 -4 exp -1 Rxy - ?200
1010
In this VanRhijnls data, on absorption in si: Kapteyn
areas (L 1101 8? 19 81 9 24 with galactic longitudes
07 17, 80, 92, 10~1 1~8) wish L,< + 3.1 were used. The
distance of the sun from the ce~t*Se-of the Galaxy (R0) was
taken as 7.2 Kps.
Using the expressions fort DR and DZ the mass of the
Galaxy is estimated to be abou 5 x 108M
The deviation of densities from the logarithmic law of
distribution in low latitude directions agrees with the
spiral structure in the solar vicinity, determined from the
maxima in the distribution of B stars (Bergedorf Spectral
Durchmusterung (7)) and the maxima in the distribution of

with the help o the above ormulae tte)da Kharadze (1)

give tables of A(r) for different r.
All 'the areas SA) were givided into four roups:
1P 0
1 0-590), 11 ~ t = 59-81 ), III ( 4 = 81-118 ),
IV 118-1430). Table 1 indicates the grouping of the
material. The first Z_M_mn. Kharadze; second column: VanPkijn.
In Table 2 (P-35) are shown: the ranges of Z within which
the-mean values ~,T were calculated (1st column), the mean
Z coordinate (second column) corresponding values of )4
(third column) their logarithms (fourth colilmn), the
number of points (n), and the mean distance from the sun in
the galactic plane r XY, There are four groups of these columns
Fig.1 (P-36) gives a plot of log 'AT versus z using
Kharadze's data. For large Z the data are few and not very
reliable.
Group IV was then divided into three Bub-groups for b> 200~
200< b < 400 and b > 400 and log 'Al was plotted against
Z for no wirlee sub-grouts As can be seen some sort
of relation does exist be ween the density gradient and Z.
There is not enough data for quantitative analysis of this
relation.

ABSTRACT: An investigation was made of the gas content of transformer

The charge of the open hearth heats consisted 40%, of pig iron.
5% of swarf, and 1501o of Fe, the rest being open-hearth depart-
ment returns and rolling department scrap. 100 kg pig iron were
added before tapping. Ferrosilicon (75% Si) was added in the

before the smelting of the charge. It was found that there is a constant in-
crease in [H] during an open-hearth heat up to the very pouring of the rnctdl
while in electric steel making it diminishes even after the oxidizing slag has
been removed. The rate of oxidation of C makes for elimination of N and for
some increase in [H ] . After the addition of the Fe-Si and the Al, [H I rises.
[N I diminishes until pouring, but rises during the pour period. The [H] and
NI of steel diminish during rolling and annealing. 0 and H increase wattage
losses, and in addition H dimishes the magnetic induction.

TEXT: The values of the mass-transfer coefficients through z1ag in basic
and acid processes are approximately estimated. For the basic process at pure
ebullition D - 1.~5 cm 2/min The h rogen permeability of the slag for this
period is 5.22 cm /min-cm3/;oo g mmV2 of mercury. After reduction of the vat
D w 0.65 crr.2/mln. The hydrogen permeability is 2.24 cm"2/min_cm3/j(o g mml/2 mer-
cury. For the acid silicon reduction proceso D - 1.13 cm2/min. The hydrogen per-
meability is 2.81 cm2/min-cm3/100 g mmi/2 of mercury, The mass transfer coeffi-
cient of H2 for the silicon reduction process is lower by a factor of 1.5, and the
hydrogen permeability of the alkalinic slag Is greater by a factor of 2 than that

of the acid process. Despite the elimination of H2 by means of CO bubbles, the
process of 112 absorption by the metal dominates the process of liberation. The.
higher the VC, the more 110 is eliminated and the greater, is its qUantlty absorbed
by the vat. An Increase in 1'2 concentration In the metal during the smelting
process indicates the fact that Its content tends to some definite quantity, whict,
may be thought of as the equilibrium concentration of 112- The measurements or 112
solubility were carried out on a Sieverts-type laboratory apparatus. The equi-
librium concentration of H2 for the conditions of open-hearth steel was calculated
from the solubility measured. The interaction reaction of water vapor with molten
Fe -.H2 as + FeOmolten in Fe ~ Femolten + H20 as' lies at the basis of the cal-
cula.io� Of the equilibrium concentration. Af temperatures of a s~eel-smelfdng
vat and at 02 content equal to 0.02%. the value of the ratio PH-ra/P11, fluctuates
between the limits 0.10 - 0.14, 1. e. 90 - 95% of the water vapor is being de-
composed, Consequently, into the equationjHj= k1i VP_11" instead of the partial

of water vapor and of 112 in the gaseous phase in the open-hearth flirnace. Ac-

TEXTt The results of an experimental Investigation are d soussed with ref-
erences to data of nineteen works partly confirming the authoraf conclusions and
partly illubtrating that the existing opinions on the process are different. Three
alloys were malted 14 the subject experiments: a) Fe - C (0.8 - 1.0% C. 0,10 Mn,
0,01 31,'0-015 P, OX04 S, 0.1 - 0.3 Al)j b) Fe - S (0.02.C, 0410 Mn, 0.01 Si,

helium (with not more than 0.13% N and 0.006% 0 ), nitrogen (N99.0%) an4 ohlorine,
~i 0.04 - 0.1 atm pressure; the eifect of mi~Q was also ptudied. The mixing
of metal by blowing and stirring did not exceed the usual rilming in shop furnaces.
The vcperlmental results are illustrated In graphs and a table. Gas.neutril to
hydroken bad no effect on'its eltmination; nitrogen caused an -abrupt increase of
the hydrogen-conoentraticp in the metal; ohlorine.raised the dehydrogenation
rate not only by the [H] + [H] f -(H 21 Bur eaction, but by the formation
of HC1 as well that was ffiftPunder IM9 Helt conditions. The obtained data as well
an observations in other works made previously indicated pulsations and an unsteady
motion of the raising gas bubbles in the metal. It is apparent that no resistant
lam1nal films exist on 'the boundary between the metal and gas bubbles, the liquid
metal layer on the boundary with the gas bubble is being permanently renewed, and
the rate of element transf6r from the volume to the free surface depends on the
rate of turbulent diffusion. Hence If an element liberates frow.the surface layer
into the gaaeous phase through a chemical reaction at a limited rate, it is very
probable that just this reaction will be limiting the process rate. It may there-
fore be concluded thqt the hydrogen liberation process from liquid steel during
Card 2/3

s/148/6i/ooo/oo2/ool/oii
The process of hydrogen liberation from liquid steel A161/A133
rimming in furnaces and during blowing in ladles Is kinetic. The stage limiting
the process is the stage of hydrogen recombination in the surface layer with simul-
taneous desorption of the molecule Into gaseous phase. Concluslonst 1) The rate
of hydrogen elimination In blowing, through the induction Mrnace crucible is limit-
ed by the rate of recombination (with simultaneous molecule desorption) on the
metal-gas boundary. 2) The factors having the strongest effect on the rate of the
process are - the blown gas consumption. the depth to which the blowing pipe is
submerged iii metal, the metal temperature, and the pipe nozzl& holes diameter.
Neither the chemical combosition of the metal nor the nature of gas beihg*blown
(if it does not react with hydrogen) do have any noticeable effect on the rate of
hydrogen elimination. 3) The laboratory~tes~ results and a co4arison of mixing
effect lead to the conclusion that the hydrogen elimination process is also kinetic
at the rimming of metal in industrial furnaces and during the blowing'in ladles.
