What is the difference between fused magnesia and large crystalline fused magnesia?

2020-12-01

Large crystalline fused magnesia consumption process: large crystalline fused magnesia is mainly made of 91-92% magnesium oxide and 0mm-3mm magnesium oxide particles, which are melted in an arc furnace. The product has high purity, large crystalline particles, fine structure, slag resistance, good thermal shock fluctuation, is an excellent low temperature electrical insulation data, but also the manufacture of high-grade magnesia brick, magnesia carbon brick and unshaped refractory material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components and so on.

Product characteristics of large crystalline fused magnesia: high purity, crystallization granule melting, high junction, fine structure; Good thermal shock fluctuation; Excellent low temperature flexural strength; It has excellent slag resistance and corrosion resistance function; ; Strong thermal conductivity and high insulation. Commercial use of large crystalline fused magnesia: large crystalline fused magnesia is used for lining refractory materials of steelmaking furnace. It is a high-quality and high-grade alkaline refractory material for manufacturing refractory bricks and unshaped refractory materials. It can also be used as filler for the manufacture of thermocouple and thermal insulation data (household appliances, etc.); It can also be used for ceramic materials and sintering auxiliaries as well as metallurgy, building materials, chemical industry, national defense, medical instruments and so on.

Secondary characteristics of fused magnesia products: fused magnesia products is characterized by structure intact, fine, high melting point (2800 ℃) arrived, chemical function, compression strength, insulation function is strong, erosion resistance, corrosion resistance, is metallurgy, building materials, light industry, important material, lining and bulk material and steel, cement, glass, non-ferrous metal smelting and other professional no lack of important refractory materials. Melting magnesia is mainly used to use 47% magnesite, melting in an electric arc furnace.

The chemical targets of fused magnesia can be divided into 6 items: 1. 2, silica content; 3, iron trioxide content; 4, aluminum oxide content; 5. Caustic soda; 6. Body density; Fused magnesia products have high purity, large crystalline particles, fine structure, slag resistance data, good thermal shock fluctuation, is an excellent low temperature electrical insulation data, but also the manufacture of high-grade magnesia brick, magnesia carbon brick and amorphous refractory material.

Secondary purpose: fused magnesia fused magnesia secondary can be used for patching material, ramming material for refractory materials and flow of the steel brick, magnesite brick, magnesite chrome brick electrician grade magnesium oxide powder, 97 fused magnesia, fused magnesia 98 and other special firebrick, can also be used in vacuum and vacuum induction furnace, electric arc furnace refractory lining, is all kinds of magnesia crucible furnace and manufacturing the aspirations of casing material at low temperature.
