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
