The fused magnesia is mainly prepared by melting 47% or more of magnesite ore in an electric arc furnace. The chemical index of fused magnesia can be divided into 6 major items; 1. Magnesium oxide content; 2. Silica content; 3. Ferric oxide content; 4. Aluminum oxide content; 5. Caustic soda; The fused magnesia product has high purity, large crystal grains, compact structure, strong slag resistance, good thermal shock resistance, and is an excellent high-temperature electrical insulating material. It is also a high-grade magnesia brick, magnesia carbon brick and no. An important raw material for shaping refractories. The main features of fused magnesia products: fused magnesia products are characterized by complete structure, compact structure, high melting point (up to 2800 ° C), stable chemical properties, high compressive strength, strong insulating properties, erosion resistance, corrosion resistance, Metallurgy, building materials, light industry, furnace lining and bulk materials are also important refractory materials in the steel, cement, glass, non-ferrous metal smelting and other industries. The main use of fused magnesia: fused magnesia can be mainly used for auxiliary refractory materials such as spray materials, ramming materials, and special refractory bricks such as flow steel bricks, magnesia bricks, magnesia chrome bricks, etc., and also in vacuum and non-vacuum. The induction furnace and the electric arc furnace are made of refractory lining, which is an ideal raw material for making magnesia crucible, furnace and various high temperature casings. Large-crystal fused magnesia production process: Large-crystal fused magnesia is mainly obtained by using 91%-92% magnesium oxide and 0mm-3mm magnesium oxide particles, which are melted in an electric arc furnace. The product has high purity, large crystal grain, compact structure, strong slag resistance and good thermal shock resistance. It is an excellent high-temperature electrical insulating material and is also important for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories. raw material. Widely used in metallurgy, chemical, national defense, scientific research, aerospace, household appliances and other components. Large crystalline fused magnesia product characteristics: high purity, large crystal melting, high knot, compact structure; good thermal shock resistance; good high temperature flexural strength; good slag resistance and corrosion resistance; High performance and high insulation. Large crystal fused magnesia product use: Large crystal fused magnesia is used as a lining refractory material for steelmaking furnaces. It is a high-quality alkaline refractory raw material for the manufacture of refractory bricks and amorphous refractories. It can also be used as a filler. Thermocouples and thermal insulation materials (home appliances, etc.); can also be used for ceramic raw materials and sintering auxiliaries as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc. Led Round Downlight,Recessed Round Downlight Led,Led Recessed Round Lighting,Recessed Led Round Downlight Foshan Extrlux Co., Ltd. , https://www.extrlux.com
