Magnesia Brick

Magnesia Brick
The company uses high-grade magnesia and strict process to produce magnesium oxide content of more than 90%, with periclase crystalline phase mainly basic refractories.
Magnesia brick has high refractoriness, good alkali resistance slag resistance, high load softening starting temperature, but poor thermal shock resistance. Sintered magnesia brick to brick magnesia brick as raw material, crushing, ingredients, kneading, after molding at a high temperature 1550 ~ 1600 ℃ firing, high-purity products in firing temperature above 1750 ℃. Unfired magnesia brick is added to the appropriate chemical binding agent in the magnesia by mixing, forming, drying made.
Mainly used for steelmaking basic open hearth furnace bottom and the furnace wall, the permanent lining oxygen furnace, non-ferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, furnace and hearth furnace wall, glass furnace regenerator checker bricks and so on.
