Product introduction 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 type of refractory material without calcination.
Features of silicon carbide castable
Silicon carbide castable: good wear resistance and corrosion resistance, high temperature strength, high thermal conductivity, low linear expansion coefficient, good thermal shock resistance.
Applications of silicon carbide castable
Silicon carbide castable is widely used in metallurgy, iron and steel industry, silicon carbide castable thermal conductivity is large, heat transfer is fast, can save energy, and will not cause a sharp cooling solution, for casting and refining temperature provides a strong guarantee.
