Product Introduction
This product is mainly made of high-quality high alumina bauxite as the main raw material, with phosphate as the binder and special materials such as "three stones" added. It is formed under high pressure and lightly fired through a special process. It has the characteristics of high load softening temperature, high temperature strength, erosion resistance, and excellent thermal shock stability.
