High-purity fused aluminum-chromium sand is mainly made of magnesite ore with a content of more than 47% and melted in an electric arc furnace. The chemical indicators of high-purity fused magnesia can be divided into 6 major items of fused aluminum-chromium sand; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Ferric oxide content; 4. Aluminum oxide content; 5 , Burning loss; 6. Bulk density; high-purity fused magnesia products have high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulating material. It is also an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.

Main features of high-purity fused magnesia products: high-purity fused magnesia products are characterized by complete structure, dense organization, high melting point (up to 2800 ° C), stable chemical properties, high compressive strength, strong insulation performance, erosion resistance, Corrosion resistance is an important raw material for metallurgy, building materials, light industry, furnace lining and bulk materials, and an indispensable important refractory material for steel, cement, glass, non-ferrous metal smelting and other industries.
Main uses of high-purity fused magnesia: High-purity fused magnesia can be mainly used for auxiliary refractory materials such as gunning material and ramming material, as well as special refractory bricks such as flow steel mouth bricks, magnesia bricks, and magnesia-chrome bricks. Vacuum and non-vacuum induction furnaces and electric arc furnaces are used as refractory linings, and are ideal raw materials for making magnesia crucibles, furnaces and various high-temperature casings.
Large crystal fused magnesium production process: Large crystal fused magnesium is mainly made of high-purity magnesium oxide with a content of 95%-98%, 0mm-3mm magnesium oxide 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 insulating material, and is also an important material for making high-grade magnesia bricks, magnesia-carbon bricks and unshaped refractories. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components, etc.
Product use of large crystal fused magnesia: large crystal fused magnesia is used as the lining refractory material of steelmaking furnace, and it is a high-quality and high-grade basic refractory raw material for making refractory bricks and unshaped refractory materials; it can also be used as a filler for making Thermocouples and thermal insulation materials (household appliances, etc.); also used in ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc.
