Brief introduction of magnesia brick
Basic refractory with magnesium oxide content above 90% and periclase as the main crystal phase.
Generally, it can be divided into two categories: sintered magnesia brick (also called fired magnesia brick) and chemically bonded magnesia brick (also called unfired magnesia brick). Magnesium brick with high purity and high firing temperature is called directly bonded magnesium brick because of the direct contact of periclase particles; Bricks made of fused magnesia are called fused recombined magnesia bricks.
Magnesium brick has high fire resistance, good alkali slag resistance, high initial softening temperature under load, but poor thermal shock resistance. Sintered magnesia brick is made of brick-making magnesia brick, which is crushed, mixed, molded and sintered at the high temperature of 1550 ~ 1600℃. The sintering temperature of high-purity products is above 1750℃. Pouring-free magnesia brick is made by adding appropriate chemical binder into magnesia, mixing, molding and drying.
Mainly used for steelmaking alkaline open hearth furnace, furnace bottom and wall, oxygen converter permanent lining, nonferrous metal smelting furnace, high-temperature tunnel kiln, calcined magnesium brick and cement rotary kiln lining, heating furnace bottom and wall, glass kiln regenerator checker brick, etc.
