Refractory Sintered Magnesia Chrome Brick For Cement Kilns And Glass Furnaces
Product Description of Rongsheng Refractory Factory High Quality Refractory Sintered Magnesia Chrome Brick For Cement kilns And Glass Furnaces
Sintered magnesia chrome bricks are a type of refractory brick, which are heat-resistant materials used in linings for furnaces, kilns, incinerators and other high-temperature environments.
They are made from sintered magnesia (magnesium oxide, MgO) and chromite (chromium(III) oxide, Cr2O3) as the main components. Sintering is a process of compacting and forming a material by heating it below its melting point. This process gives the bricks their high strength and resistance to high temperatures
