      Alumina Silicon Carbide Carbon Castable Characteristic

      Alumina silicon carbide carbon castable is mainly used for the casting of blast furnace iron trough. Alumina silicon carbide carbon castable’s main materials are fused corundum(or sintered corundum, special grade bauxite clinker), graphite contains 90%~95% fixed carbon, silicon carbide and so on.
