Supply of re-burned magnesia, mid-range magnesia, high-purity magnesia, fused magnesia, can be used to process various types of granular materials 0-1mm, 1-3mm, 3-5mm, 5-8mm, 8-15mm, etc., mesh materials 100 mesh, 180 mesh, 200 mesh, 320 mesh, etc. Fused Magnesia
The use of magnesia has attracted more and more attention with the development of the magnesia industry, and magnesia has become an important product in industrial production. Price of fused magnesia 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 magnesite materials such as magnesite to reach the sintering degree. 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 and other raw materials are smelted in an electric arc furnace to reach a molten state for cooling 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.
Steelmaking light burnt magnesia ball
The reburned magnesia is made from natural magnesite ore and calcined in a high-temperature shaft kiln. The magnesium content is mgo80-93%. The purpose of burnt magnesia: raw materials for making bricks and producing unshaped refractory materials, and the finished products are used for steelmaking, electric furnace bottom and ramming furnace lining.
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, compact structure, strong slag resistance, good thermal shock stability, and magnesium content of mgo93-98%. Therefore, the purpose of heavy fused magnesia is: it is an excellent high temperature Electrical insulation materials are also important raw materials for making high-grade magnesia bricks, magnesia carbon bricks and unshaped refractory materials.
Mid-grade magnesia is made of light-burned magnesia as raw material, produced by pressing ball, high temperature shaft kiln calcination and other processes. The product has good sintering degree, dense crystals, and magnesium content of mgo-95%. The purpose of mid-range magnesia is: it is used to produce unshaped refractory materials such as magnesia bricks, mid-range magnesia bricks, magnesia castables, and is a high-quality raw material for magnesia refractory products.
High-purity magnesia is made by flotation and purification of natural super magnesite ore, which is lightly burned, finely ground, pressed ball, and calcined in ultra-high temperature oil shaft kiln. Magnesium content mgo96-97% high-purity magnesia is used as an ideal raw material for high-grade magnesia refractory materials such as magnesia bricks, magnesia bricks, magnesia carbon bricks, ramming materials for tundishes, and magnesia castables.
