Discusses possibility of using tailings, obtained in
flotation of talcum-magnesite, as magnesia addition in
fabricaticoof forsterite refractories out of dunite.
Sharp improvement in sintering capacity of forsterite
mmas may be achieved under condition of fine disper-
sion of dunite and joint grinding of dunite vith

magnesia admixture. Activation of sintering in this
case is explained by destruction of magnetite and
magnesioferrite interlayers which separated zones of
foraterite crystals in former grains of olivine. This
facilitates contact among forsterite crystals and
~'romotes their recrystallization.

TITLE: Alumina-Chromite Refractories for Lining Steel-Pouring Ladles.
(Glinozemistokhromito,vyye ogneupory dlya futerovki

PERIODICAL: Metallurg, 1,057, Nr 9, pp.17-18 (USSR)
ABSTRACT: Tests on 100 ton steel-pouring ladles at the Chelyabinsk
metallurgical works showed that the durability of a lining
of alumina-~-chromite bricks (77-38% Al 20 , 6.70% SiO Y 10.81%
_9% R30; refracto;ies over
Cr9939 1.17% Fe 203' 1.02% MgOq 3-9 2
18006c, porosity at 19.6%) was greatly superior to that of a
firebrick one. It is estimated that the service life of
alumina-cbromite linings could amount to 20-22 heats (com-
pared with 7.6 heats for firebrick). Further investigation
is recommended for elucidating factors capable of still
further increasing durability, particularly the use of a
thinner lining, and for arriving at improved brick-production
methods to reduce thermal conductivity. There is 1 figure.

TITLE: An Investigation of the Dolomite From the Source of
Sukhorechensk as a Raw Material for the Production of
Metallurgic Dolomite (Issledovaniye dolomitov sukhorechensl:ogo

PERIODICAL: Ogneupory, 1958, Nr 2, PP. 72-78 (USSR)
ABSTRACT: Judging from the color there exist three types of dolomite:
a pale gray, a gray and a deep gray variety. The chemical
composition and the physical properties of dolomite are given
in table 1. The figure shows the micro structure of dolomite,
which is subsequently discussed. The method of Kukolev and
Dolgina was employed for an assessment of the sintering power.
Tables 2, 3, and 3a give the results of the determination of
sintoring power. Dolomite showed a considerable increase
in weight after the baking process (table 4). In the court3e
of this invest4ation the influencesof additions, as there
are tinder, a concentrate of titanium magnetite, titanium
dioxide and zirconium dioxide were additionally examined.
These investigations also showed, that the net grinding of
Card 1/3 dolomite in a ball mill guarantees the sintering of all samples

An Investigation of the Dolomite From the Source of 131-2-5/10
Sukhorechensk as a Raw Material for the Production of
Metallurgic Dolomite
at 15000C, with and without additions (table 5).
Subsequently, the problem of sintering is explained and
illustrated by fi8ures 21 3 and 4. Among others, the final
conclusions contain the following statements; The dolomite
from the source of Sukhorechensk represents a qualified raw
material for the production of baked metallurgical dolomate.
With respect to its chemical composition it corresponds to the
specifications of class 1
MTIT~2660 - 50
The gray variety shows the widest distribution. If dolomite
is baked in pieces, it sinters at a minimum temperature of
17000C, except the pale gray variety, which needs only 16500C-
An admixture of tinder of from 2-5 % lowers the sintering
temperature to 1500-16000C. The admixtures increase its
resistivity to hydration.
There are 4 fiCures, 6 tables, and 6 references, 5 of which
Card 2/3 are Slavic.
