TITLEt Coke Fig-Iron (Chugun paredellnyy koksovyy,'
PERIODICALs Standartizatsiya, 1958, # 1, pp 42-43 (USSR)
LBSTRLCTt The article deals with the new "GOST 80"-57"-standard
for pig-iron, which, since October 1957, has replaced the
"GOST 805-49" and requires low manganese content in pig-
iron for the production of open hearth steel. The Magnito-
gorsk and Kuznetsk Metallurgical Combines were the pioneers
in this matter and achieved, respectively, 2.6% and 4%
economy of coke, 3% and 41% higher productivity of blast
furnaces, and about 20 r ubles economy per ton of pig-iron.
All plants of the Eastern region of the USSR followed suit.
In October 1954, an All-Union conference of blast furnace
specialists decided to try the method at one of the plants
of the Southern USSR which works on highly sulfurous coke.
The Central Institute of Iron Metallurgy also met with
success at the Metallurgical Plant imeni Dzerzhinskiy in
1955. Blast furnace productivity increased by 3.45,(, coKe
limestone, and mangqnsse ore consumption decreased by 3.42%,
6.3%, and 80%, respectiv4tly. Practical experience has proved,
Card 112 that the manganese content in pig-iron Joes not have tne

Coke Pig-Iron 28-58-1-15/54
technological importan:e in the open hearth melting process
as was believed before. It was found at the imeni Dzer-
zhinskiy Plant, Viat in order to reduce the sulfur content
in pig-iron, it Is necessary to increase the basicity of slag,
and an increased magnesia content in slag keeps it fluid.
Additions of dolomitized limestone can be made for this
purpose. Satisfactory results were also obtained in the
open hearth scrap process (with 52% of 1,1g-iron and 68%
scrap) at the Zlatoust Metallurgical Plant. In 19115, an All-
Union conference of steel smelters decided to accept low-
manganese pig-iron, and a corresponding technological in-
etruction for steel smelting was considered. The articIR in-
cludes two charts illustrating that the manganese content in
the liquid metal of open hearth furnaces Joss not depend on
the manganese content in pig-iron and does not chanige.
There are 2 charts.

ABSTRACT: The authors studied minerals of the series MeB2Oq()H)2-M2B20-3(011)2- The
parameters of the unit cell'were calculated for the entire series. A dependence of
the parameters, position, and intensity of the absorption bands on the chemizql com-
position ic established. The possibilities are discussed of crediting the ir bands
to vibrations of the B-O-R2* and OH-Mg, OH-Mn groups. The formula (Mg, Mn)2B205(OH)2
is proposed in place of the formla (Yg, Mn)HB03, since it has been established
spectroscopically that the B20~j groups and free OH are present. These singularities
are characteristic also of the natural minerals. (Translation of abstract)

The work of USSR scientific research organizations on improving the
technology of heat-resistant concretes (HRO and their utilization is re-
viewed. A method of producing heat-resistant cements which up to 1000 0
do not lose strength has been developed, based on portland and aluminous
cements. This consists of introducing 0.5 - 3% of boron oxides (figures
converted to elementary boron) into the &luminous and portland clinkers
whilst roasting, and 1-7',- of boron oxides into the fireclay, subsequently
milling,the clinker ~30 - 70%) and firoclay (70 - 30%) together. A HRC
efficient up to 1600 C has been produced on a portland cement base, using
finely Around chromit* or sagnesito as binder and chromite as filler. HRC

'rFIXT The strength of refractory concretes depends on the density of
water glass, particle size of filler, sodium fluosilicate content, water
glass modulus and firing temperature. The temperature of firing was
studied for, largICnumber of specimens and it was found that in gene6a)
heating to ~01400 increased the strength, whilat firing at 400-600 C
tended to reduce it, propgrtionally to the sodium fluosilicate content.
Further heating up to 600 C, produced no change. The strongest toncretea

strength As compared with specimens heated to DO C. Specimenseith inag,,
n*sits filler showed a gradual deterioration of strength between 100 1100
C, due to the thermal expansion of the filler. Dunite and talc filler*
proved unsatisfactory while andesit* gave similar results tQ chamotto.
In the ma3erity of Lefractory concrete& the strength tended to increase
when heated to 1000 C. The temperature limit for concretes based or
water glass was determin,gd by the temperature of deformation under 2 kX (w
loads. The temperaturo of the onset and end of deformation was found
to depend on the nature of filler, sodium fluosilicat* content and water
KI&AB modulus The highest temperature, under the above load was W-th
stood by specimens contiiining crHobed magnesite brick filler. Only 4%
deformation was observed at 1280 C and the saflening occurred within a
2400C interval, By increasing the sodium fluosilicate content from 10
20% and reducing water glass modulus from 2.8 2.1 it was possi1le to
lower the temperature of deformation by 100 aC, The air setting of the
