High-quality Dead Burned Magnesia Refractory Brick is a product made of high-grade molding and high-temperature firing using first-grade magnesia and high-purity magnesia as raw materials. Dead Burned Magnesia Refractory Brick has excellent heat resistant and high resistance to alkali slag erosion.
Magnesium brick has high refractoriness, good alkaline slag resistance, high initial temperature of softening under load, but poor thermal shock resistance. Sintered magnesia brick is made of magnesia brick as raw material, after crushing, batching, mixing and molding, it is fired at a high temperature of 1550~1600℃, and the sintering temperature of high purity products is above 1750℃. Unpoured magnesia brick is made by mixing, forming and drying with appropriate chemical binder in magnesia.
It is mainly used for basic open hearth furnace, electric furnace bottom and wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and lining of cement rotary kiln, furnace bottom and wall of heating furnace, lattice brick of regenerative chamber of glass kiln, etc.
