Description
Magnesium brick product introduction
An alkaline refractory material having a magnesium oxide content of 90% or more and a periclsite as a 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.
An alkaline refractory product containing periclase as the main phase. The product has the characteristics of high temperature mechanical strength, good slag resistance, strong corrosion resistance and stable volume at high temperature.
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 ° C. The high-purity product has a firing temperature of 1750 ° C or higher. The non-casting magnesia brick is made by adding a suitable chemical binder to the magnesia, mixing, forming and drying.
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.
Production Equipment
