Fused magnesite is mainly used for more than 47% magnesite, obtained by melting in an electric arc furnace. Molten magnesia chemical indicators 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
6, body dense
Fused magnesia products with high purity, large crystal grains, compact structure, strong slag resistance materials, thermal shock resistance is good, is an excellent high temperature electrical insulation materials, but also the production of high-grade magnesia, magnesia carbon bricks and amorphous Refractories an important raw material.
The main characteristics of fused magnesia products: fused magnesia products are characterized by structural integrity, dense structure, high melting point (up to 2800 ℃), chemical stability, compressive strength, strong insulation, erosion resistance, corrosion resistance, is Metallurgy, building materials, light industry, lining and bulk materials, an important raw material, but also steel, cement, glass, non-ferrous metal smelting and other industries indispensable important refractories.
Fused magnesia main purposes: fused magnesia can be used mainly for refilling materials, ramming material and other auxiliary refractories and flow gate brick, magnesia brick, magnesia chrome brick and other special refractory brick, but also in vacuum and non-vacuum Induction furnace, arc furnace to do fire-resistant lining, is the production of magnesia crucible, furnace and a variety of high temperature casing the ideal raw material.
Large crystal fused magnesia production process: Large crystalline fused magnesia is the selection of 91% -92% magnesia, 0mm-3mm size magnesium oxide particles, obtained in the electric arc furnace melting. The product has the advantages of high purity, large grain size, compact structure, strong slag resistance and good thermal shock resistance, which is an excellent high temperature electrical insulation material and is also important for making high grade magnesia bricks, magnesia carbon bricks and unshaped refractories. raw material. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household appliances and other components.
Large crystalline fused magnesia Product features: high purity, crystal grain melting, high point knot, compact structure; good thermal shock resistance; good high temperature bending strength; good slag resistance and corrosion resistance; thermal conductivity High performance, high insulation.
Large crystal fused magnesia Usage: Large crystal fused magnesia used in steelmaking furnace lining refractory, is to create refractory bricks, high-grade refractory refractory materials, high-grade alkaline refractory raw materials can also be used as filler for the production Thermocouples and thermal insulation materials (household appliances, etc.); can also be used for ceramic raw materials and sintering aids and metallurgy, building materials, chemicals, defense, medical equipment.
