Product Details
Kiln Linings Fire Brick Refractory High Temperature , Alumina
Corundum Bricks
Description:
The sintered corundum products were produced by sintering of high
purity fused corundum, synthetic mullite and chromium oxide. They
have high bulk density, high compressive strength, good thermal
shocking resistance, and good corrosion resistances to acids and
alkali. They are not influenced by H2, CO gases at use.
Features:
1.high bulk density
2.high compressive strength
3.good thermal shocking resistance
Applications:
Widely used as linings in decomposing furnaces for petroleum and
chemical industry,
as well as chemical fertilizer industry. They also used as high
temperature kiln linings
and furniture’s in metallurgical industry.
