The electrofused magnesite is mainly made of magnesite with 47% content by melting in an electric arc furnace.
The chemical purpose of electrofused magnesia can be divided into 6 items.
1. Magnesium oxide content;
2, silica content;
3, iron trioxide content;
4, aluminum oxide content;
5. Caustic soda;
6. Body density; Electrofused magnesia products have high purity, large crystalline particles, compact structure, slag resistance material, good thermal shock shake, is a kind of high temperature electrical insulation material, is also an important raw material for manufacturing magnesium brick, magnesium carbon brick and amorphous refractory materials. Electrofused magnesia is mainly used for spray filling material, ramming material and other auxiliary refractories and flow steel orifice brick, magnesia brick, magnesia chrome brick and other special refractory bricks, can also be used in vacuum and non-vacuum induction furnace, arc furnace lining, is the manufacture of magnesium oxide crucible, furnace and all kinds of high temperature bushing ideal raw materials.
Commercial use of large crystalline fused magnesia: large crystalline fused magnesia is used in furnace lining refractory material, is the manufacture of refractory bricks, unshaped refractory materials of high quality alkaline refractory raw materials; Can also be used as a filler for the manufacture of thermocouples and thermal insulation materials (household appliances, etc.); It can also be used for ceramic raw materials and sintering auxiliaries as well as metallurgy, building materials, chemical industry, national defense, medical equipment and other electrically fused magnesia products. Fused magnesia products are characterized by incomplete structure, compact structure, high melting point (2800 ℃) arrived, chemical function, compression strength, insulation function is strong, erosion resistance, corrosion resistance, is metallurgy, building materials, light industry, lining and the loose material, the important raw materials for steel, cement, glass, non-ferrous metal smelting and other industries indispensable important refractory material.
Large crystalline fused magnesia consumption process: Large crystalline fused magnesia is mainly selected 91-92% magnesium oxide, 0mm-3mm magnesium oxide particles, melting in an electric arc furnace. The product has high purity, large crystalline particle, compact structure, strong slag resistance, good thermal shock shake, is a kind of high temperature electrical insulation material, is also an important raw material for manufacturing magnesium brick, magnesium carbon brick and unshaped refractory materials. 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, compact structure; Good thermal shock shaking; It has good high temperature bending strength; It has good slag resistance and corrosion resistance function. Strong thermal conductivity and high insulation.
