Fused magnesia Main characteristics of products: fused magnesia products are characterized by complete structure, dense organization, high melting point (up to 2800 ℃), stable chemical performance, high compressive strength, edge, erosion resistance and corrosion resistance. They are important raw materials for metallurgy, building materials, light industry, furnace lining and bulk materials, as well as important refractory materials for steel, cement, glass, non-ferrous metal smelting and other industries.

The fused magnesite is mainly made from magnesite ore with a content of more than 47% by melting in an electric arc furnace. The chemical indexes of fused magnesia can be divided into 6 items; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Fe2O3 content; 4. Aluminum oxide content; 5. Caustic soda; 6. Body density; The fused magnesia product has large crystal grain, compact structure, slag resistant material and good thermal shock stability. It is an excellent high temperature electrical flange material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.

Main uses of fused magnesia: fused magnesia is mainly used for auxiliary refractory materials such as gunning materials and ramming materials, electrical grade magnesia powder for flow-through bricks, magnesia bricks, magnesia chrome bricks, 97 fused magnesia, 98 fused magnesia and other special refractory bricks, and can also be used as refractory lining on vacuum and non vacuum induction furnaces and electric arc furnaces. It is an ideal raw material for making magnesia crucibles, furnace liners and various high-temperature casings. 　

Production process of large crystal fused magnesia: large crystal fused magnesia is mainly made by melting 91% - 92% magnesium oxide particles with the size of 0 mm - 3 mm 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.
