Introduction
Chromium Corundum Raw Materials (also
called Chrome Corundum Material), Chromium corundum (Pink Fused
Alumina, Pink Fused Aluminium Oxide, Chromium Aluminum Oxide) is a
pink/rose abrasive made of high-purity alumina and a proper amount
of chromium oxide in an arc furnace. The content of alumina
(Al₂O₃) is
more than *8%, and there is about 0.7% chromium oxide
(Cr₂O₃) and
0.3% Naâ‚‚O.
Chromium corundum is an excellent abrasive with a wide range of
applications due to its high hardness, good toughness, good
self-sharpness, high cutting finish, low magnetic content,
concentrated particle size, and pure content.
Â
Compared with pure white corundum,
Crâ‚‚O₃ is a high-quality component of
refractory materials, capable of forming high-melting compounds
with various oxides. For example, Crâ‚‚O₃ and Alâ‚‚O₃ can form a continuous solid
solution with a melting point above ***0 °C;
Crâ‚‚O₃ and MgO/FeO form a high melting
point magnesia-chromium spinel/ferrochrome spinel;
Crâ‚‚O₃ and Cuâ‚‚O can
form a compound with a melting point above ***0 °C; the melting
temperature of the eutectic formed by Crâ‚‚O₃ and SiOâ‚‚ reaches
***0℃,
etc.
Â
Chromium corundum is a product made by
reducing Crâ‚‚O₃ with pure alumina. It is
equivalent to a composite refractory made by adding more than *0%
pure Crâ‚‚O₃ to melted pure corundum (or white
corundum). Due to the high content of Crâ‚‚O₃ and its binding to the corundum
matrix, it is called chromium corundum. Chromium corundum undergoes
high-temperature smelting above ***0°C in the production process,
resulting in a more uniform composition due to its good thermal
stability and high-temperature chemical
stability.
Â
The high density of chromium corundum
is the key factor in improving the lining life. After melting, the
solidified chromium corundum block has small porosity, so the key
part of the furnace body is built with chromium corundum, and the
gaps in the bricks are filled with chromium corundum powder and
binder.
