Alumina fused cast refractories: Alumina fused cast refractories are whereby highly pure alumina raw material is melted at over 2000 C and poured into a mold. Comparing with fused cast AZS refractories, their contamination to molten glass is very low. They are perfect compliments to the AZS rang for sensitive application. Fused cast AZS series: AZS series are a high quality Al2O3-ZrO2-SiO2 fused cast refractories, consisting of crystallized baddeleyite (ZrO2) and corumdum (Al2O3), and matrix glass. It is made by melting refined raw materials through a Heroult type electric arc method under a throrough quality control process. Ramming mixes AZS 50V,AZS 06L,AZS 04J three kinds of unshaped refractory materials have already formed a complete set.
