Product Description

Product Description:

Magnesia Chrome Brick is a kind of refractory material, which is made of magnesia (MgO) and chromium oxide (Cr2O3) as the main raw materials and fired at high temperature. It has good thermal shock resistance and good corrosion resistance. It is widely used in the blast furnace, hot blast stove, glass kiln and other thermal equipment. The thermal expansion coefficient of Magnesia Chrome Brick is between 2.5-3.5×10-6/℃, the chemical composition is MgO-Cr2O3, the porosity is less than or equal to 22%, and the cold crushing strength is greater than or equal to 50 MPa. Magnesia Chrome Bricks are widely used in metallurgy, ceramics, glass, chemical, and other industries as a lining material or a heat insulation material. And it can also be used for the inner and outer walls of the furnace, the bottom and roof of the furnace, the smelting zone, the transition zone and other parts of the furnace. Magnesia Chrome Brick has good thermal shock resistance, corrosion resistance, thermal insulation and other properties. It is an ideal choice for furnace lining and heat insulation.
