Description


The magnesium oxide content of magnesia brick is 90%-98%. Magnesia brick has good fire resistance and corrosion resistance. It uses magnesium oxide or fused magnesia as raw materials and is fired at a high temperature of 15501600°C. It is the firing of high purity products. The temperature is above 1750℃. They are corrosion resistant and are widely used in various high temperature furnaces.

Magnesia brick has the advantages of strong alkali corrosion resistance, strong erosion resistance, good thermal stability, high compressive strength, and high load softening temperature.

The refractoriness of magnesia bricks can reach more than 2000 ℃, and its load softening temperature varies greatly with the melting point of the cemented phase and the number of liquid phases produced at high temperatures. Generally, the starting temperature of load softening of magnesia bricks is between 1520 and 1600℃, while high-purity magnesia bricks can reach 1800℃.

Features

Higher temperature resistance and good refractoriness / Excellent resistance to alkaline erosion

Strong erosion resistance / Good thermal stability

High compressive strength / High load softening temperature

Application

Magnesia bricks are widely used in metallurgy (electric furnaces, converters, mixing furnaces), non-ferrous metals (smelting furnaces), high-temperature tunnel kilns, sintered magnesia kilns, building materials (cement rotary kilns, glass melting kilns, new lime kilns), steel rolling (soaking) Furnace, heating furnace) etc.
