With the development of magnesia industry, people pay more and more attention to the use of ordinary fused magnesia, and magnesia has become an important product in industrial production. Understanding the use of magnesia is of great significance for better development of magnesia industry. Magnesia is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the degree of sintering. Magnesia calcined with natural magnesite as raw material by one or two step calcination process with high-temperature equipment such as shaft kiln and rotary kiln is called sintered magnesia; The fused magnesite is formed after magnesite and other raw materials are melted in the electric arc furnace and cooled. Magnesia is one of the important raw materials for refractories, which is used to manufacture various magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks, ramming materials, furnace repair materials, etc. It contains many impurities and is used to pave the bottom of the steelmaking furnace. Magnesia can be divided into fused magnesia, medium-grade magnesia, high-purity magnesia and re-burned magnesia. Manufacturer of fused magnesia

There are two main specifications of medium-grade magnesia, one is 94%, the other is 95%. The medium-grade magnesia is mainly used in metallurgy to manufacture metallurgical powder, which is used to join furnace bottom and furnace wall, manufacture slurry spray furnace lining, and manufacture magnesia brick and magnesia chrome brick. In addition to being used as furnace lining for furnace bottom, it is also widely used in electric steelmaking furnace, heating furnace, non-ferrous metal converting furnace and rotary furnace, and is also a high-quality raw material for producing medium-grade magnesia refractory products. Magnesia manufacturer

The reburning magnesite is mainly composed of magnesite with a content of more than 46%. When the magnesite is calcined and heated to 1400-1800 ℃ in a high temperature shaft kiln, Mg (CO3) is completely decomposed to form periclase, which becomes a hard reddish-brown reburning magnesium with high fire resistance. It is an ideal raw material for the production of unshaped refractory materials. The products are used for the steel making open hearth, electric furnace bottom and ramming furnace lining.
