Common magnesia-chrome brick with strong resistance to alkaline slag Used in electric furnace, refining furnace
Product description:
The basic refractory products with square magnesite and magnesia-chrome spinel as the main crystal phase are called magnesia-chrome bricks.
Category of Refractory Brick/Fire Brick:
Magnesia-chrome brick is divided into ordinary magnesia-chrome brick, directly combined magnesia-chrome brick, electrofused semi-recombined magnesia-chrome brick and electro fused magnesia-chrome brick.
Features:
Common magnesia-chrome brick is generally produced from sintered magnesia (MgO content 89%~92%) and refractory grade chrome brick as raw materials.Common magnesia-chrome brick has the advantages of high strength, erosion resistance, good slag resistance, good thermal stability, etc., and is mainly used in non-ferrous metal smelting furnace, steelmaking electric furnace, converter, refining ladle, glass kiln, cement kiln firing belt, etc.
