Industrial High Purity Fused Magnesite

The fused magnesia spinel is made from high-purity light-burned magnesium powder and industrial alumina powder. After smelted by a large high-temperature electric arc furnace, the fused alumina magnesium spinel has the characteristics of high density, good appearance, good corrosion resistance and good thermal shock resistance. It inherits the advantages of high melting point and low expansion coefficient, alkali resistance especially alkaline residue from alumina and magnesia. Meanwhile, it avoids the high expansion coefficient of Magnesium Oxide, poor alkali resistance of aluminum oxide. Therefore, fused alumina magnesium spinel is widely used in the top of steel-making electric furnace, converter , ladle, large cement rotary kiln firing zone, excessive belt and glass regenerator that need alkaline resistance slag, wear resistance and high refractoriness.   

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.
