MgO Magnesia Brick/Magnesia Brick

Product Description

We are among the reliable companies, we are engaged in manufacturing, exporting and supplying of MgO Magnesia Brick/Magnesia Brick in Zhengzhou, Henan, China Magnesia brick is an alkaline refractory material with a magnesia content of more than 90% and a periclsite as the main phase. Generally, it can be divided into two categories:sintered magnesia brick (also known as burnt magnesia brick) and chemically combined magnesia brick (also known as non-burned magnesia brick). Magnesia bricks with high purity and high firing temperature are called direct-bonded magnesia bricks because of the direct contact of the magnesite grains. The bricks made of fused magnesia are called electrofusion and recombined magnesia bricks. Magnesia bricks have high refractoriness, good resistance to alkaline slag, high starting temperature of load softening, but poor thermal shock resistance. The sintered magnesia brick is made of brick and magnesia bricks. After being pulverized, compounded, kneaded and formed, it is fired at a high temperature of 1550 to 1600 A C. The high-purity product has a firing temperature of 1750 A C or higher. The non-casting magnesia brick is made by adding a suitable chemical binder to the magnesia, mixing, forming and drying. Magnesia brick Mainly used in steelmaking alkaline open hearth furnace, electric furnace bottom and furnace wall, permanent lining of oxygen converter, non-ferrous metal smelting furnace, high temperature tunnel kiln, calcined magnesia brick and cement rotary kiln lining, heating furnace bottom and furnace wall, Glass kiln regenerator lattice bricks, etc. Magnesia brick The sintered magnesia brick is made of brick and magnesia bricks.
