Corundum Refractory Bricks, Alumina Corundum Brick High Temperature Kiln Linings
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.
