There are several types of fused magnesite

There are three main types of fused magnesite sand. 1. Ordinary fused magnesite, low silicon and high calcium calcium fused magnesite, and large crystalline fused magnesite;

1. The common electrofused magnesite products are mainly made by melting over 47% magnesite or lightly burnt magnesia in the arc at high temperature. Magnesite grain size, compact structure, strong slag resistance, high temperature stability of volume. Main USES of fused magnesite: fused magnesite is mainly used as a good raw material for advanced alkaline bricks, carbon products and amorphous refractories.

2. Low-silicon and high-calcium fused magnesite products are mainly made from low-silicon magnesite, which is smelted by high-temperature electric melting furnace. Its characteristic is that the ratio of calcium to silicon is greater than 2, the grain is fully developed, and the volume density of the particle is greater than 3.50g/cm3. Low silicon and high calcium point fused magnesite is mainly used for medium frequency induction furnace smelting, high manganese steel, stainless steel, high gong steel, high alkaline brick, carbon products and amorphous refractory materials.

3. Production process of large crystal fused magnesite: large crystal fused magnesite is mainly produced by melting and melting in an arc furnace with selected natural magnesite or high quality, high purity and light firing magnesium particles. The product has high purity, crystal grain of large, compact structure, strong slag resistance, good thermal shock stability, is a kind of excellent high temperature electrical insulation materials, is also a production of high-grade magnesia brick, magnesia carbon brick and important raw materials of amorphous refractory material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.

Characteristics of large crystalline fused magnesite products: high purity, large melting of crystalline grains, high junction, compact structure; Good thermal shock stability; It has good high temperature bending strength. It has good slag resistance and corrosion resistance. High thermal conductivity and high insulation.

Purpose of large crystal fused magnesite products: large crystal fused magnesite is used as lining refractory material for steel furnace, it is a high quality alkaline refractory material for making firebrick and unshaped refractory. It can also be used as filler to make thermocouple and thermal insulation materials (household appliances, etc.). It can also be used for ceramic materials and sintering AIDS as well as metallurgy, building materials, chemical industry, national defense, medical equipment and so on.
