Magnesite brick MZ90-MZ98 is made from high purity magnesia. The higher the content of MgO, the higher the temperature, the higher the direct combination of the Chinese magnesia crystal, and the better the high temperature performance and anti-erosion performance. The high density and high temperature strength, high temperature strength and slag resistance are better. Magnesia brick is widely used in the permanent lining of steel furnace, lime kiln, glass kiln, ferroalloy furnace, mixer, nonferrous metal smelting furnace etc. After asphalt impregnation, it is commonly used as the steel outlet and the vulnerable part of the metallurgical furnace.
