Product description
High-quality magnesite refractory bricks is a product made of high-grade molding and high-temperature firing using first-grade magnesia sand and high-purity magnesia sand as raw materials. magnesite refractory bricks has excellent heat resistant and high resistance to alkali slag erosion.
Application of magnesite refractory bricks:
Magnesite refractory bricks are mainly used in steelmaking basic open hearth furnace, electric furnace bottom and furnace wall, oxygen converter permanent lining, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, heating furnace bottom and furnace wall, glass kiln regenerator cell lattice brick, etc.
