What is the difference between large crystal fused magnesia and fused magnesia

Large-crystalline fused magnesia product features: high purity, large crystal grain melting, high point junction, dense structure; good thermal shock stability; good high temperature flexural strength; good slag resistance and corrosion resistance; thermal conductivity Strong performance and high insulation.

Large crystalline fused magnesia product use: Large crystalline fused magnesia is used as the refractory lining for steelmaking furnaces. It is a high-quality high-grade alkaline refractory raw material for the manufacture of refractory bricks and unshaped refractory materials; it can also be used as a filler for production. Thermocouples and thermal insulation materials (home appliances, etc.); can also be used in ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc.

The main characteristics of fused magnesia products: fused magnesia products are characterized by complete structure, dense structure, high melting point (up to 2800 ° C), stable chemical properties, high compressive strength, strong insulation performance, erosion resistance, corrosion resistance, It is an important raw material for metallurgy, building materials, light industry, furnace lining and bulk materials. It is also an indispensable important refractory material for steel, cement, glass, non-ferrous metal smelting and other industries.

Fused magnesia is mainly made by selecting magnesite ore with a content of 47% or more in an electric arc furnace. The chemical index of fused magnesia can be divided into 6 items: 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Iron oxide content; 4. Aluminium oxide content; 5. Caustic soda; 6. Body density ; Fused magnesia products have high purity, large crystal grains, compact structure, strong slag resistance and good thermal shock stability. They are an excellent high-temperature electrical insulation material. An important raw material for shaped refractories.

Fused magnesia main uses: Fused magnesia can be mainly used for auxiliary refractory materials such as spraying and ramming materials, and electrical grade magnesia powder for flow steel mouth brick, magnesia brick, magnesia chrome brick, 97 fused magnesia, 98 fused magnesia and other special refractory bricks can also be used as refractory linings 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 bushings.
