Refractory Raw Material Fused Magnesite

Fused Magnesia (MgO) is normally manufactured by the electric arc melting of caustic calcined magnesia, deadburned magnesia or raw magnesite in furnaces at temperatures in excess of 2750°C, producing a refractory product whose altered crystalline structure is such that its characteristics and performance are superior to competing materials.

Main characteristics of fused magnesia products: Fused magnesia products are characterized by complete structure, compact structure, high melting point (2800 ℃), stable chemical performance, compression strength, insulation performance is strong, erosion resistance, corrosion resistance, is metallurgy, building materials, light industry, lining and the loose material, the important raw materials for steel, cement, glass, non-ferrous metal smelting and other industries indispensable important refractory material. 

The main uses of fused magnesia: fused magnesia can be used as auxiliary refractory materials such as injection filler, ramming material and special refractory bricks such as flow steel mouth brick, magnesia brick, magnesia chrome brick, etc. It can also be used as refractory lining in vacuum and non-vacuum induction furnace and electric arc furnace. It is the ideal raw material for making magnesium oxide crucible, furnace liner and various high temperature bushing.
