Product Introduction:
Silicon Carbide Brick is a kind of refractory product mainly made of SiC, and the silica carbide content is 72%~99%. Generally, it's made by the black silica carbide( content above 96%).
Features:
1. Good abrasion resistant.
2. Good strength at high temperature.
3. Good thermal shock resistance.
4. Small thermal expansion rate.
Application:
Silicon carbide bricks can be used for metallurgical steel cylinder lining, nozzle, plug, blast furnace bottom and hearth,non-ferrous metal smelting still, electrolytic cell side wall, smelting metal crucible, silicate industry furnace sheds and flame-proof materials, oil and gas generators in the chemical industry, organic waste combustion furnaces and aluminum refining furnace linings, etc.
