The main features of fused magnesia products: fused magnesia products are characterized by complete structure, dense organization, high melting point (up to 2800℃), 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, and is also an indispensable important refractory material in steel, cement, glass, non-ferrous metal smelting and other industries.

Fused magnesia is mainly made of magnesite ore with a content of 47% or more and melted in an electric arc furnace. The chemical indicators of fused magnesia can be divided into 6 major items; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Iron oxide content; 4. Aluminum oxide content; 5. Caustic soda; 6. Body density ; Fused magnesia products have high purity, large crystal grains, dense structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and it is also the production of high-grade magnesia bricks, magnesia carbon bricks and other materials. An important raw material for shaped refractories.

The main application of fused magnesia: fused magnesia can be mainly used for auxiliary refractory materials such as gunning materials and ramming materials, as well as electrical grade magnesia powder for laminating bricks, magnesia bricks, magnesia chrome bricks, 97 fused magnesia, Special refractory bricks such as 98 fused magnesia can also be used as refractory linings on vacuum and non-vacuum induction furnaces and electric arc furnaces. They are ideal raw materials for making magnesia crucibles, furnace galleries and various high temperature casings. 

Large-crystalline fused magnesia production process: Large-crystalline fused magnesia is mainly made of 91%-92% magnesium oxide, 0mm-3mm size magnesia particles, and melted in an electric arc furnace. The product has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material and is also important for making high-grade magnesia bricks, magnesia carbon bricks and unshaped refractories. raw material. It is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household appliances, etc.

Product characteristics of large crystalline fused magnesia: high purity, large melting of crystal particles, high point structure, compact structure; good thermal shock stability; good high-temperature flexural strength; good slag resistance and corrosion resistance; heat conduction Strong performance and high insulation.

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