Magnesia is an excellent high temperature electrical insulating material

Magnesia is a refractory material, which takes magnesia (magnesia) as the basic aggregate, mixes it with magnesium chloride solution, adds a small amount of talc, quartz sand, glass wire, and knotted to form. It has a fire resistance of 400 degrees Celsius and a high energy of 1700 degrees. Heavy - fired magnesium, good sintering degree, uniform chemical composition, stable quality. Mainly used for steelmaking open hearth furnace, electric furnace sintering furnace bottom and ramming lining.

Magnesia preparation arc melting method, is made of magnesium high materials as the basic raw materials, such as magnesite, water magnesite, light burned magnesia, dead burned magnesia, etc.), in different types of electric melting furnace in high temperature by arc heating (greater than 3000 ° C), make magnesia raw material is heated in a furnace, and decarburization (to adopt magnesite stone), dehydrated magnesium (bright water stone), melting, crystallization and crystal grew up, cooling and a series of physical and chemical change process, made of fused magnesia with various physical properties. These crystals are then processed into electrosoluble magnesium oxide suitable for a variety of USES.

Purpose: The products are used for magnesia brick, Magnesia aluminum brick, Magnesia chrome brick, spray material, castable material, dry material, daub material, filler material, asphalt, casting, fireproof and heat preservation material, flux accessories, electric furnace, heating furnace, rotary furnace, steelmaking, electric furnace bottom and ramming furnace lining. Large crystal electrofused magnesia products are mainly produced by melting magnesium oxide particles with 90% or more content in an arc furnace. The product has high purity, large crystal particles, compact structure, strong slag resistance, good thermal shock stability, is an excellent high temperature electrical insulation material, and is also an important raw material for the production of high-grade magnesia bricks, magnesia carbon bricks and amorphous refractory materials. Widely used in metallurgy, chemical industry, national defense, scientific research, aerospace, household electrical components.

Characteristics of large crystal electrofused magnesite: high purity, large melting of crystal particles, high junction point and compact structure; Good thermal shock stability; Good high temperature flexural strength; It has good slag resistance and corrosion resistance. Strong thermal conductivity, high insulation. Purpose: Large crystal electrofused magnesite is used as lining refractory for steel furnace, and is a high quality and high grade basic refractory material for refractory brick and unshaped refractory. It can also be used as a filler to make 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 so on.
