The brick is made of high-quality bauxite clinker as aggregate and fine powder, white mud and paper pulp as binder, with addition of silicon carbide, sillimanite, mullite and other admixtures, and is formed by a 630-ton press, which is reasonable. The high-grade refractory materials produced by the firing process have the characteristics of normal temperature, middle temperature, high temperature strength, high load softening point, good wear resistance, good thermal shock stability, etc.
