There are several kinds of fused magnesia

There are three types of fused magnesia: ordinary fused magnesia, low silicon high calcium fused magnesia, large crystal fused magnesia 98 fused magnesia

1. Ordinary fused magnesia products are mainly made of magnesite light burned magnesia with more than 47% content by high temperature melting in arc. Periclase has large grain size, compact structure, strong slag resistance excellent volume stability at high temperature. Main uses of fused magnesia: fused magnesia is mainly used as a good raw material for advanced basic bricks, carbon containing products unshaped refractories.

2. Low silicon high calcium fused magnesia products are mainly made of low silicon magnesite by high temperature electric melting furnace. Its characteristics are that the ratio of calcium to silicon is more than 2, the grains are well developed, the bulk density of particles is more than 3.50g/cm3. Low silicon high calcium spot melting magnesia is mainly used as good raw material for medium frequency induction furnace melting, high manganese steel, stainless steel, high steel, high-grade basic brick, carbon containing products unshaped refractories.

3. Production process of large crystal fused magnesia: large crystal fused magnesia is mainly made by melting selected super natural magnesite high-quality high-purity light burned magnesium particles in electric arc furnace. The product has high purity, large crystal grain, compact structure, strong slag resistance good thermal shock stability. It is an excellent high temperature electrical insulation material an important raw material for making high-grade magnesia brick, magnesia carbon brick unshaped refractory. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.

Characteristics of large crystalline fused magnesia: high purity, large melting point, dense structure; good thermal shock stability; good high temperature bending strength; good slag resistance corrosion resistance; strong thermal conductivity high insulation.

Application of large crystal fused magnesia products: large crystal fused magnesia is used as lining refractory of steel-making furnace. It is a high-quality high-grade basic refractory material for making refractory bricks unshaped refractory materials. It can also be used as filler for making thermocouple thermal insulation materials (household appliances, etc.). It can also be used as ceramic raw materials sintering additives, as well as metallurgy, building materials, chemical industry, national defense medical equipment so on.
