Product description of silicon carbide castable
Silicon carbide castable is made of high grade silicon carbide and industrial silicon powder. This is a kind of amorphous refractory. It is made of refractory aggregate, refractory powder, binder and other additives. It is a new refractory material without calcination.
Features of silicon carbide castable
Silicon carbide castable: good wear resistance and corrosion resistance, high temperature strength, high thermal conductivity, small linear expansion coefficient, good thermal shock resistance.
Application of silicon carbide castable
Widely used in metallurgy, iron and steel industry, silicon carbide castable has large thermal conductivity, fast heat transfer, can save energy, and will not cause a sharp cooling solution, providing a strong guarantee for the casting and refining temperature.
