The characteristics of large-crystalline fused magnesia: large-crystalline fused magnesia is mainly made of 91%-92% magnesium oxide, 0mm-3mm magnesia particles, and melted in an electric arc furnace. The product has high purity, large crystal grains, fine structure, strong slag resistance, and good thermal shock fluctuation. It is a kind of low-temperature electrical insulation material and an important raw material for the manufacture of magnesia bricks, magnesia carbon bricks and unshaped refractory materials. It is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household appliances, etc.
Commercial characteristics of large crystalline fused magnesia: high purity, large crystal grains, high melting point, fine structure; good thermal shock resistance; excellent low temperature flexural strength; excellent slag resistance and corrosion resistance; heat conduction function Strong and highly insulated.
Commercial use of large crystalline fused magnesia: large crystalline fused magnesia is used as a refractory material for the lining of steelmaking furnaces. It is a high-quality alkaline refractory material for making refractory bricks and unshaped refractory materials; it can also be made into fillers for manufacturing Thermocouples and thermal insulation materials (household appliances, etc.); can also be used for ceramic materials and sintering aids for metallurgy, building materials, chemicals, national defense, medical equipment, etc.
The secondary characteristics of fused magnesia products: the characteristics of fused magnesia products are complete structure, fine structure, high melting point (up to 2800℃), stable chemical function, high compressive strength, strong insulation function, 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 important refractory raw material indispensable for professions such as steel, cement, glass, and non-ferrous metal smelting. Fused magnesia is mainly made of magnesite ore with a content of more than 47% and melted in an electric arc furnace.
The chemical targets 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. density; Fused magnesia product has high purity, large crystal grains, fine structure, strong slag resistance, and good thermal shock fluctuation. It is a kind of low temperature electrical insulation material, and it is also a material for manufacturing magnesia bricks, magnesia carbon bricks and unshaped refractory materials. Important raw materials.
Secondary use of fused magnesia: secondary use of fused magnesia can be used for auxiliary refractory materials such as gunning materials and ramming materials and tapping pipe bricks, magnesia bricks, magnesia chrome bricks, electrical grade magnesia powder, 97 electric 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. They are high-quality raw materials for manufacturing magnesia crucibles, furnaces and various low-temperature casings.
