Product Introduction
Product Details
Production method:
Fused cast and recombined magnesia-chrome brick is also called fused grain magnesia-chrome brick. The high temperature performance is between the cast magnesia chrome brick and the sintered magnesia chrome brick, and its load softening temperature can reach 1700 degrees C. Generally, the light burned magnesium oxide and chrome ore are used as raw materials, and the molten magnesium chrome sand is made by electric arc furnace, and then it is made by crushing, grinding, batching, molding and firing. The application field of this brick is similar to that of ordinary magnesia chrome brick.
