Shangzhi fused magnesia market quotation
What does magnesite do; Magnesite is divided into three categories: sintered magnesia, light burned magnesia and fused magnesia. Magnesite is one of the important raw materials for refractories, which is used to manufacture various magnesia bricks, magnesia alumina bricks, ramming materials, furnace repairing materials, etc. Those with more impurities are used to pave the bottom of the steelmaking furnace.

Use of large crystal fused magnesia products: large crystal fused magnesia is used as lining refractory of steelmaking furnace, and is a high-quality high-grade alkaline refractory material for making refractory bricks and unshaped refractory materials; It can also be used as filler to make thermocouple and thermal flange materials (household appliances, etc.); It can also be used as ceramic raw materials and sintering aids, as well as metallurgy, building materials, chemical industry, national defense, equipment, etc.

Magnesia produced by smelting magnesite in an electric furnace at 2750 ℃ is called fused magnesia. Generally, it has very strong high temperature resistance, is not easy to be melted by alkaline substances, is not easy to be eroded by molten metals at high temperatures, and has excellent thermal conductivity at room temperature. The high refractory carbon magnesia brick (composed of graphite and fused magnesia) made from it as raw material is widely used in converter steelmaking and secondary refining. The smelting cycle is shorter, the furnace life is longer, and the quality of steel is improved.

Magnesite is calcined at high temperature from magnesite, bischofite or magnesium hydroxide extracted from seawater. It is a general term for the products of magnesite and other magnesia raw materials that have been treated at high temperature to reach the sintering process. Magnesite sintered from natural magnesite is made by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln; Seawater magnesia is produced by extracting magnesium oxide from seawater after magnesite and other raw materials are melted in an electric arc furnace and cooled.
Shangzhi fused magnesia market quotation
Electric fused magnesia is made by melting selected extra natural magnesite or high-purity light burned magnesium particles in an electric arc furnace. This product has large crystal particles, compact structure, slag resistant materials, and good thermal shock stability. Therefore, the purpose of heavy electric fused magnesia is: it is an excellent high-temperature electrical flange material, and also an important raw material for making high-grade magnesia bricks, magnesia carbon bricks, and amorphous refractories

Yingkou dicalcium fused magnesia is the main raw material selected, which contains 92% magnesium oxide. The magnesium oxide is pressed into balls by a ball press. The shape of the pressed ball is 30mm, and the 30mm magnesium oxide ball is calcined in the high-temperature oil shaft kiln or coke shaft kiln. The calcined product is called medium grade magnesia, which is mainly used to produce high-grade basic shaped or amorphous refractories, and its finished products are mainly used in metallurgy, building materials, non-ferrous metals, chemical industry and other industries.
