Introduction of High quality Electric Fused Rebonded Magnesia Chrome Brick Magnesite-chrome Brick For Furnace

Rebonded Magnesite-Chrome bricks are a type of high-level refractory product material ,which contain MgO and Cr2O3 as the main components, periclase and spinel are the main mineral components. This type of brick has high refractoriness, high temperature strength, strong resistance to alkaline slag, excellent thermal stability, and certain adaptability to acidic slag. The main raw materials for the manufacture of magnesia chrome bricks are sintered magnesia and chromite. The purity of the magnesia raw material should be as high as possible.

Features of Magnesia Chrome Brick

(1).high refractoriness

(2).high temperature strength

(3).strong resistance to alkaline slag

(4).excellent thermal stability

Appplication of Magnesia Chrome Brick

Common mag-chrome brick: Cement rotary kiln, glass kiln regenerative chamber, glass tank furnace ,steel furnace lining, refining ladle, non-ferrous metallurgical furnace, lime kiln, mix iron furnace, open hearth furnace.
Direct-Bonded mag-chrome brick : Cement rotary kiln, steelmaking electric furnace lining, refining furnace(RH,VOD,EAF), non-ferrous metallurgical furnace, glass kiln regenerative chamber, lime kiln, mix iron furnace, building materials, copper smelting furnace.
