As the development of the magnesia industry has attracted more and more attention, 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. Magnesium is a general term for products produced by high-temperature treatment of magnesia raw materials such as magnesite to the extent of sintering. Using high-temperature equipment such as shaft kilns, rotary kilns and other high-temperature equipment for one-step calcination or two-step calcination process, magnesia fired with natural magnesite as raw material is called sintered magnesia; magnesite, etc. are used as raw materials to be melted and cooled by electric arc furnace smelting The latter is called fused magnesia. Magnesia is one of the most important raw materials for refractory materials, used to make various magnesia bricks, magnesia alumina bricks, magnesia carbon bricks, ramming materials, and repairing materials. Containing more impurities, it is used to pave the bottom of steelmaking furnaces, etc. Magnesia can be divided into fused magnesia, mid-range magnesia, high-purity magnesia and re-burned magnesia. Fused magnesia is made by fusing selected special A-grade natural magnesite or high-purity light-burned magnesia particles in an electric arc furnace. The product has high purity, large crystal grains, dense structure, strong slag resistance, good thermal shock stability, and magnesium content of mgo96-98%. Therefore, fused magnesia is an excellent high-temperature electrical insulation material. An important raw material for the production of high-grade magnesia bricks, magnesia carbon bricks and unshaped refractories! Fused skin sand
