Silicon Carbide Refractory Castable
Silicon carbide refractory castable is a kind of refractory castable. It has high temperature resistance, high strength and high thermal conductivity. It is mainly used in steel nozzles, waste incinerators, electric arc furnace roofs, etc. Rongsheng Group, as a professional refractory manufacturer in China, we have a large inventory. In addition, we provide a variety of high-quality refractory products and enjoy discounted ex-factory prices.
Composition of Silicon Carbide Castable
Silicon carbide refractory castable is mainly composed of refractory aggregates, refractory powders, and additives. These raw materials contribute to its excellent performance. Besides, there are many high temp castable refractory for you to choose from.
Refractory aggregates and powders include silicon carbide, corundum, alumina, zircon, silicate cement, and so on.
Additives include retarders, water reducers, enhancers, and so on.
Advantages of Silicon Carbide Refractory Castable
High-temperature resistance: Silicon carbide has a melting point of 1750 degrees Celsius. It exhibits high resistance to high temperatures.
Thermal shock resistance: It has a low coefficient of thermal expansion and can withstand extreme thermal stresses.
Good abrasion resistance: Silicon carbide has a hardness second only to diamond. This feature allows it to withstand heavy loads and mechanical wear.
Corrosion resistance: This material is suitable for environments with high levels of acid and alkali corrosion.
Good thermal conductivity: This material has excellent thermal and electrical conductivity. It is usually used in parts requiring heat dissipation.
Application of Silicon Carbide Castable
Silicon carbide castable is mainly used for wear parts, kiln linings, iron tapping holes, and so on. Its application is in the following high-temperature kilns: steel furnaces, aluminum smelting furnaces, waste incinerators, cement kilns, cyclone furnaces, fluidized bed furnaces, boilers, and other kilns.
