  • Product description

With the development of magnesia industry, more and more attention has been paid to it, and magnesia has become an important product in industrial production. Understanding the use of magnesia is of great significance for the better development of the magnesia industry. Magnesia is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperatures to achieve a sintering degree. Magnesia produced by using high-temperature equipment such as shaft kilns and rotary kilns as a single or two-step calcination process and using natural magnesite as raw material is called sintered magnesia; Using magnesite and other raw materials as raw materials, which are melted in an electric arc furnace and cooled to a molten state, is called fused magnesia. Magnesia is one of the important raw materials for refractory material Z. It is used for manufacturing various magnesium bricks, magnesium aluminum bricks, magnesium carbon bricks, ramming materials, furnace repair materials, etc. Containing a large amount of impurities, it is used to pave the bottom of the steelmaking furnace, etc. Magnesia can be divided into fused magnesia, medium grade magnesia, high purity magnesia, and heavy burned magnesia. Electrofused magnesia is produced by melting selected grade A natural magnesite or high-purity calcined magnesium particles in an electric arc furnace. This product has high purity, large crystalline particles, compact structure, strong slag resistance, good thermal shock stability, and magnesium content of 96-98%. Therefore, fused magnesia is an excellent high-temperature electrical insulation material, and is also an important raw material for producing high-grade magnesia bricks, magnesia carbon bricks, and amorphous refractory materials!
