Product introduction of silicon carbide castable
The content of silicon carbide castable is generally between 80 and 95, the volume density can reach 2.6, the compressive strength is more than 40 mpa, is the ideal material for non-ferrous metal smelting industry flow trough, insulation furnace lining, refining furnace, reduction furnace lining.
Features of silicon carbide castable
Silicon carbide castable anti copper, aluminum and other non-ferrous metal penetration ability is very strong, anti-erosion, anti-spalling, 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 to provide a strong guarantee.
