Product Introduction
Corundum Castable for RH Vacuum Degassing Furnace is formulated using high-purity corundum and spinel as the primary aggregates, combined with a specially designed composite bonding system. The material features an extremely low impurity content and a dense microstructure, ensuring excellent performance under severe refining conditions.The castable offers exceptional high-temperature strength, outstanding resistance to molten steel and slag corrosion, superior resistance to high-velocity erosion, and excellent volume stability. It also exhibits remarkable thermal shock resistance and easy installation characteristics, making it an ideal refractory solution for critical RH furnace applications.Specifically engineered for the severe operating conditions of RH vacuum degassing furnaces, the product is widely used in snorkels, vessel bottoms, and other areas subjected to intense thermal, chemical, and mechanical stresses.
