Fused magnesia There are three main types; 1、 Ordinary fused magnesia, II. Low silicon high calcium fused magnesia, III, large crystal fused magnesia; Magnesite manufacturer

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

2. Low silicon and high calcium fused magnesia products are mainly made from low silicon magnesite by melting in a high temperature electric furnace. Its characteristics are that the calcium silicon ratio is greater than 2, the grains are fully developed, and the bulk density of particles is more than 3.50g/cm3. Low silicon and high calcium point melting magnesia is mainly used as a good raw material for medium frequency induction furnace smelting, high manganese steel, stainless steel, high gong steel, advanced basic bricks, carbon containing products and unshaped refractories.

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

Characteristics of large crystal fused magnesia products: large melting of crystalline particles, high point structure, dense structure; Good thermal shock stability; Good high temperature bending strength; It has good slag resistance and corrosion resistance; Heat conduction, height edge.

Use of large crystal fused magnesia products: large crystal fused magnesia is used as lining refractory of steelmaking furnace, and is a high-quality high-grade alkaline refractory material for making refractory bricks and unshaped refractory materials; It can also be used as filler to make thermocouple and thermal flange materials (household appliances, etc.); It can also be used as ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemical industry, national defense, equipment, etc.
