There are three main types of fused magnesia; 1. ordinary fused magnesia; 2. low-silicon high-calcium fused magnesia; 3. large-crystalline fused magnesia; Yingfeng

1. Ordinary fused magnesite products are mainly made by using magnesite or light-burned magnesite with a content of 47% or more as the main raw materials to melt at high temperature in an arc. The periclase has large grains, dense structure, strong slag resistance, and excellent volume stability at high temperatures. The main uses of fused magnesia: fused magnesia is mainly used as a good raw material for advanced alkaline bricks, carbon-containing products and unshaped refractory materials.

2. Low-silicon and high-calcium fused magnesia products are mainly made of low-silicon magnesite and smelted by high-temperature electric furnace. Its characteristics are that the calcium-silicon ratio is greater than 2 and the grains are fully developed. Low silicon high calcium point molten magnesia is mainly used as a good raw material for medium frequency induction furnace melting, high manganese steel, stainless steel, high gong steel, high-grade alkaline brick, carbon-containing products and amorphous refractory materials.

3. Large crystalline fused magnesia production process: Large crystalline fused magnesia is mainly made by selecting and using special grade natural magnesite or high-quality high-purity light-burned magnesium particles and melting in an electric arc furnace. This product has high purity, large crystal grains, compact structure, strong slag resistance, and good thermal shock stability. It is an excellent high-temperature electrical insulation material, and it is also important for the production of high-grade magnesia bricks, magnesia carbon bricks and unshaped refractory materials. raw material. It is widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, and household appliances.

Large-crystalline fused magnesia product features: high purity, large crystal grain melting, high point junction, dense structure; good thermal shock stability; good high temperature flexural strength; good slag resistance and corrosion resistance; thermal conductivity Strong performance and high insulation.

Large crystalline fused magnesia product use: Large crystalline fused magnesia is used as the refractory lining for steelmaking furnaces. It is a high-quality high-grade alkaline refractory raw material for the manufacture of refractory bricks and unshaped refractory materials; it can also be used as a filler for production. Thermocouples and thermal insulation materials (home appliances, etc.); can also be used in ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemicals, national defense, medical equipment, etc.
