ABSTRACT: The --laGo mentioned ir, the title are u.,jed for the
production of clag cauting to in cvcr greater extent
(Refs 1-4). At present this production is carried out
according to the polygonal method whore crystallization
of the alaC melts takes place during a slow cooling
in the cast containers. The rcs;~P-ctive crystallization
processes are, however, insufficiently known fRefs12,*
and thic circumstance led to the pr,~uelit inveo i,,,r:.t on.

from half an hour to one hour at these temperatures
secures a sufficient degree of crystallization
and a high mechanical strength. The use of the mentioned
heat treatment will considerably shorten the duration
of the production cycle in mechanized production.
Low crystallization temperatures will simplify production.
These recommendations are also valid for the rest of
the Ural blast-furnace slags, as the latter differ
only little from the three types investigated. There are
8 figures, 2 tables, and 5 references, 5 of which are
Soviet.

TITLE., The influence of the chemical composition on the
properties of pyroxene atone castings
PERIODICAL: Izvestiya vyaahikh uchebnykh zavedeniy. Khimiya i
khimicheakaya tekhnologiya, v-5, no.4, 1962, 629-635
TEXT, The influence of chemical composition on crystallization,
melti-ng temperature and chemical resistance of crystallized V
castings was investigated. For this purpose, nine structural-
chemical complexea and compounds were chosen which contain all
oxides entering the composition of atone castings (Na20 -Al203-4SiO2)
Na20-Fe2O3*4SiO2, MgO-FS203'SiO2, CaO-FO203-Si-02, CaO*A'203 'S102
MgO-Al2O3'SiO2, CaO*TiO2-Al203, Mg0-Ti0'Z-A1203 and CaO-FeO-2SiO2).
Increasing quantities of the complex ~r compound, calculated to
obtain monomineral pyroxene castings with increasing weight % of
pne or the characteristic oxides, were successively added to
diopside. The respective melts were retained at temperatures of
11000C-and below, in 100% intervals for 2, 6 and 12 hours. The
degree of crystallization wasassessed at first visually and then on
petrographic specimens. The melting temperature wak determined

according to 9057-49 (GOST 9057-49)- Similar tests were
also made with a melt of a composition corresponding to pure
diopside (CaO - 25.9%, MgO - 18.6%, S102 - 55-5%), The resistance
to acid and alkali was tested by treating I g powdered samples of
the casts with sulphuric acid of specific gravity 1.84 and 1.14 and
a 20% solution of sodium hydroxide. The undissolved percentage
was used as a measure of acid and alkali resistance of the material.i/
Alkali containing compounds Na20.Al2O3-4SiO2 and Na20-Fe2O3-4SiO2,
introduced in small quantities, lower the temperature of the fluid
state and improve crystallization properties, simultaneously
Is ecuring sufficiently high chemical resistance. The same applies
to titanium containing complexes. Introduction of
MSO-Fe2O3'SiO2 and CaFeO-2SIO2 strongly improves crystallizing
properties and decreases the temperature of the fluid state,
"imultaneously preserving a high chemical resistance of castings.
Additions of CaO*AI203'SiO2 and MgO.Al2O3-SiO2 reduce the tendency
of melts to crystallization and the acid resistance of castings.
There are 2 figures and 5 tables.
