There are three main types of fused magnesia: 1. Ordinary fused magnesia; 2. Low silicon and high calcium fused magnesia; 3. Large crystalline fused magnesia; light burned magnesia




1. Ordinary fused magnesia products are mainly made of magnesite or light burned magnesia with a content of more than 47% as the main raw materials, which are melted at high temperature in the arc. Fused magnesia manufacturer periclase has large crystal grains, compact structure, strong slag resistance, and excellent high-temperature volume stability. The main use 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 as raw materials and smelted in a high-temperature electric furnace. Its characteristic is that the calcium to silicon ratio is greater than 2, the crystal grains are fully developed, and the particle volume density is greater than 3.50g/cm3. Low silicon and high calcium point fused magnesia is mainly used as a good raw material for medium frequency induction electric furnace smelting, high manganese steel, stainless steel, high gong steel, advanced alkaline bricks, carbon-containing products and unshaped refractory materials.

3. Production process of large-crystalline fused magnesia: large-crystalline fused magnesia is mainly made by selecting selected special-grade natural magnesite or high-quality high-purity light-burned magnesia particles and melting them 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 is also important for making 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, household appliances, 


Product characteristics of large crystalline fused magnesia: high purity, large melting of crystal particles, high point structure, compact structure; good thermal shock stability; good high temperature flexural strength; good slag resistance and corrosion resistance; Strong performance and high insulation.


Large-crystalline fused magnesia product use: large-crystalline fused magnesia is used as refractory material for the lining of steelmaking furnaces. It is a high-quality and high-grade alkaline refractory material for the manufacture of refractory bricks and unshaped refractories; it can also be used as a filler for production Thermocouple and
