Refractory for ceramic cup
    The compound brown alumina brick produced by SINOM for the ceramic cups is mainly made of secondary-calcining iron with low carbon residual brown fused alumina and quality silicon carbide by adding special additivies, then moulded under high pressure and sintered under high temperature. It has high compressive strength at room temperature, small apparent porosity, good slag penetration and molten iron corrosion resistance capacities.
