Audited Supplier 1600 degree high temperature Recrystallization silicon carbide beam
Silicon Carbide is made of high quality SIC (72%~99%)and bonded by clay, It has the following features:High thermal conductivity,
high bending strength, good thermal shock resistance. Stable chemical performance,
high cold crushing strength, good anti corrosion ability.
The products are widely used in high temperature furnace lining (furnace bottom and hearth,
furnace body, etc.), smelting non-ferrous metal furnace lining.
Silicon carbide beams lines:
1. Reaction Sintered Silicon carbide (RBSIC)
2. Recrystallized Silicon Carbide ceramic (RSC)
3. Nitride Bonded Silicon Carbide ceramic (NSC)
4. Sintered Silicon Carbide (SSiC)
Silicon carbide beams applications:
In blast furnace lining, the lining of alumina electrolytic bath and various nonferrous metal smelting,
glass tank and ceramic industries, etc. It has good heat conductivity and bearing ability under high temperature.
It is suitable to be used in structural ceramics, sanitary ceramics, domestic ceramics, electrotechnical porcelain refractory material, sinter powder metal industry.
