Electric fused magnesia is mainly produced by melting magnesite ore with a content of over 47% 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; The fused magnesia product has high purity, large crystalline particles, dense structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material and an important raw material for producing high-end magnesia bricks, magnesia carbon bricks, and amorphous refractory materials.

The main characteristics of electric fused magnesia products: Electric 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, and are important raw materials for metallurgy, building materials, light industry, furnace lining, and bulk materials. They are also indispensable important refractory materials in industries such as steel, cement, glass, and non-ferrous metal smelting.

Main uses of fused magnesia: fused magnesia can be used as auxiliary refractory materials such as gunning and ramming materials, as well as special refractory bricks such as flow steel mouth bricks, magnesium bricks, magnesium chromium bricks, etc. It can also be used as refractory furnace lining in vacuum and non vacuum induction furnaces and electric arc furnaces. It is an ideal raw material for making magnesium oxide crucibles, furnace liners, and various high-temperature casings. Large crystalline magnesia

Production process of large crystalline fused magnesia: Large crystalline fused magnesia is mainly made by melting 91% -92% magnesium oxide with 0mm-3mm magnesium oxide particles in an electric arc furnace. This product has high purity, large crystalline particles, dense structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material and an important raw material for producing high-end magnesium bricks, magnesium carbon bricks, and amorphous refractory materials. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.

Characteristics of large crystalline fused magnesia products: high purity, large melting of crystalline particles, high melting point, and dense structure; Good thermal shock stability; Has good high-temperature bending strength; Has good slag resistance and corrosion resistance; Strong thermal conductivity and high insulation.
