There are three main types of fused magnesia. 1, ordinary fused magnesia, 2, low silicon and high calcium fused magnesia, 3, large crystalline fused magnesia; 98 fused magnesia

1, ordinary fused magnesia products are mainly the use of more than 47% of magnesite or light burned magnesia as the main raw materials in the arc of high temperature melting. Brucite has large grain size, dense structure, strong slag resistance and superior volume stability at high temperature. The main use of fused magnesia: fused magnesia is mainly used for high-grade alkaline bricks, carbon products and amorphous refractories of good raw materials.

2, low silicon and high calcium fused magnesia products are mainly the selection of low silicon magnesite as raw materials, melted by high temperature electric furnace. It is characterized by a calcium-silicon ratio greater than 2, adequate grain development, and bulk density of particles greater than 3.50g/cm3. Low silicon and high calcium point fused magnesia is mainly used for medium frequency induction furnace melting, high manganese steel, stainless steel, high caustic steel, advanced alkaline bricks, carbon products and amorphous refractories.

3, the production process of large crystalline fused magnesia: The large crystalline fused magnesia is mainly the selection of special grade natural magnesite or high quality and high purity light burned magnesium particles, which are melted in the electric arc furnace. The product has high purity, large crystalline particles, dense structure, strong slag resistance, good thermal shock stability, is an excellent high-temperature electrical insulation material, but also the production of high-grade magnesia brick, magnesia carbon brick and amorphous refractories important raw materials. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and so on.

Product characteristics of large crystalline fused magnesia: high purity, large melting of crystalline particles, high point junction, dense structure; Good thermal shock stability; Good high temperature bending strength; Good slag resistance and corrosion resistance; Strong thermal conductivity and high insulation.

Large crystalline fused magnesia product use: large crystalline fused magnesia used in steel furnace lining refractory material, is the manufacture of refractory bricks, amorphous refractory materials of high quality alkaline refractory raw materials; It can also be used as a filler to make thermocouples and thermal insulation materials (household appliances, etc.); It can also be used for ceramic raw materials and sintering auxiliaries as well as metallurgy, building materials, chemical industry, national defense, medical equipment and so on.
