Fused Magnesite for Resin Bonded

It is an ideal raw material for producing firebrick and monolithic materials,with the characteristic of big crystal,compact texture,high temperature property and high slag resistance.

Fused magnesia is also used as an electrical insulating material in heating elements. Although electrical grades of fused magnesia have very tight specifications, they do not necessarily require the highest MgO contents or densities. Impurities such as sulphur and iron are particularly undesirable, but the product should contain sufficient silica to enhance its electrical properties. The following are characteristic of electrical grade fused magnesia:
•     Low levels of boron, sulphur, iron and trace elements.
•     Lime: silica ratios of 1:2 (opposite to refractory requirements).
•     Used as electrical insulating material in ceramic sheaths for heating elements.

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.
