High Temperature Refractory Kiln Shelves , Square Ceramic Kiln Furniture
Kam tai High temperature refractory Silicon carbide kiln shelves
1. Details
Refractory silicon carbide kiln shelves is distinguished by high strength that stays nearly constant up to very high temperatures (1500° C), maintaining that strength over long periods.
This material displays an extremely high corrosion resistance in acidic and basic media, and this too is maintained up to very high temperatures. These properties are outstanding among high-temperature ceramics, and are complemented by high thermal shock resistance, high thermal conductivity, high resistance to wear, and hardness close to that of diamond.
It is Widely used in various heat treatment furnace, glass annealing furnace, ceramic sintering furnace, diffusion furnace and ceramic industry, shelf panels, pillars, chemical industry, a variety of sagger, kiln liner, the environmental protection industry incinerator liner. Dimensions products, physical and chemical indicators, life had been reached or exceeded the level of similar products at home and abroad.
