Magnesite Chrome Refractory Bricks are produced from sintered magnesia and chrome ore by sintering at high temperature. Magnesite Chrome Refractory Bricks have high bulk density and advantages of stronger thermal resistance. Magnesite Chrome Refractory Bricks are widely used for;
cement rotary kilns
glass kiln regenerators
permanent lining of steel furnaces
permanent lining of refining ladles
