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, edge resistance, erosion resistance, and corrosion resistance. They are important raw materials for metallurgy, building materials, light industry, furnace lining, and bulk materials, and also important refractory materials for industries such as steel, cement, glass, and non-ferrous metal smelting.
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 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 large crystalline particles, dense structure, slag resistance material, and good thermal shock stability. It is an excellent high-temperature electrical material and an important raw material for producing high-end magnesia bricks, magnesia carbon bricks, and amorphous refractory materials.
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 steel mouth bricks, magnesia bricks, magnesia chrome bricks, 97 fused magnesia, 98 fused magnesia and other special Fire brick, 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 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 large crystalline particles, dense structure, slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical 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: 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; Thermal conductivity, high 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 Fire brick and unshaped refractory materials; It can also be used as a filler for making thermocouples and thermal materials (such as household appliances); It can also be used as ceramic raw materials and sintering additives, as well as in metallurgy, building materials, chemicals, national defense, equipment, etc.
