Specifications
Features:
Magnesia brick is generally divided into sintered magnesia brick and chemical combination of magnesia brick, also known as unfired magnesia bricks. High purity and high baking temp magnesia brick,because of MgO grain contact directly, known as a direct combination of magnesia brick; the other kind is called electro-fused magnesia bricks.Sintered magnesia brick take magnesia brick as raw material, after ingredients, crushing, mixing, forming, and 1550 ~ 1600 °C temperatures firing. High purity products firing temperature is at 1750°C or more higher.
1. High fire-resistant degree.
2. Good alkali tolerance.
3. High softening temperature under load.
Applications:
No pouring magnesia brick produced by adding proper chemical bond, then mixing, forming and drying.
Mainly used in ceramic frit furnace, sodium silicate furnace, glass melting furnace regenerator, steeling furnace, bottom and wall of electric furnace, permanent lining of oxygen converter, non-ferrous metal
smelting furnace, high temperature tunnel kiln, sintered magnesia brick and cement kiln liner.
