Silicon-carbide brick is made of SiC as raw material, by adding additives, after mixing, forming, drying, sintering at high temperature in shuttle kiln, the whole process is finished.
Feature:
1. Good thermal shock resistance.
2. High coefficient of thermal conductivity.
3. Good corrosion resistance.
Application:
Primarily used for lining of non-ferrous metal smelting, cold rolled picking line, glass annealing furnace; slab and flame proof material of heat furnace, laboratory muffle furnace, glass oven, enamel sintering furnace, diffusion furnace, etc.
