Magnesia Raw Material Details
The main component in magnesia raw material is magnesium oxide, impurities are CaO, SiO2, Fe2O3, etc. Magnesium oxide is an alkaline oxide with a melting point of 2800 degrees. After heating at high temperature, it transforms into a stable cubic crystal, commonly known as brucite. It is calcined by magnesium hydroxide at high temperature and has strong resistance to hydration.
Heavy sintered magnesia
Sintered magnesia is mainly made by calcining magnesite, magnesite or magnesium hydroxide extracted from seawater at high temperature. Strong resistance to hydration. The magnesite is calcined at 700-950 ℃ to escape CO2. The resulting magnesia is a soft porous loose material and cannot be used for refractory materials; the calcined magnesite at 1550-1600 ℃ is called sintered magnesia, which is called sintering Magnesia. The primary calcination or two-step calcination process using high-temperature equipment such as vertical kilns and rotary kilns. The burned magnesia fired with natural magnesite as raw materials is called sintered magnesia
The reburned magnesia is made from natural magnesite ore and calcined by a high-temperature shaft kiln.
It is the raw material and finished product of brick making and production of unshaped refractory materials
Used for steelmaking, electric furnace bottom and ramming furnace lining
Fused magnesia
It is called fused magnesia which is formed by using magnesite and other raw materials after melting in an electric arc furnace and cooling to a molten state;
Magnesia is an important raw material for refractory materials,
Magnesia raw materia is used to manufacture all kinds of magnesia bricks, magnesia-alumina bricks, ramming materials, and furnace filling materials.
Containing more impurities, it is used to lay the bottom of steel-making furnace.
Lightly burned magnesium powder is a material that is resistant to bending, pressure, high strength, gas hardness, and gelation, and is widely used in industries such as defense, medicine, chemical industry, papermaking, and shipbuilding. In the building materials industry, it can be used to make tire boards, chipboards, thermal insulation columns, railings, artificial marble, asbestos tiles, ordinary tiles, wallboards, and ground laying. With the advancement of science and technology, the use of lightly burned magnesium powder is more extensive, it can be used as civil products, light and heavy machinery packaging boxes, packaging bottom beams, high temperature refractory materials, and can also produce beautiful and generous gloss furniture, which can be used in the machinery industry Cast the model.
The fused magnesite is made of selected special grade A natural magnesite or high-purity light burned magnesium particles, which are melted in an electric arc furnace. The product has high purity, large crystal grains, dense structure, strong slag resistance, good thermal shock stability, is an excellent high temperature electrical insulation material, and is also important for making magnesium bricks, magnesium carbon bricks and unshaped refractory materials. raw material.
