Fused Cast Refractories
Fused cast refractories are manufactured by electro-fusing and casting process. Carefully selected high-purity raw materials are melted in Heroult type electric arc furnace at 1900 – 2500 deg.C and cooled to solidify after pouring into molds. Fused cast refractories have very high density and strength owing to electro-fusing process compared with ordinary types of refractories such as bonded refractories and stable mineralogical composition contribute to high resistance against corrosion and erosion by molten glass. Product ranges are Zirconia(X950 series), Alumina +Zirconia +Silica base (AZS/ZB series), Alumina (MB series) and Alumina-mullite (CB) fused cast refractory.
