Heilongjiang fused magnesia manufacturer
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.

Electric fused magnesia is a general term for the products of magnesite and other magnesite raw materials that have been treated at high temperature to reach the degree of sintering. Magnesite fired from natural magnesite by one-step or two-step calcination process with high-temperature equipment such as shaft kiln and rotary kiln is called sintered magnesite; The fused magnesite is formed by melting magnesite in electric arc furnace and cooling it; The magnesium oxide extracted from seawater is called seawater magnesia. Magnesite is one of the most 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.

The fused magnesia is made by melting selected natural magnesite or high-purity light burned magnesium particles in an electric arc furnace. This product has large crystal grain, compact structure, slag resistant material and good thermal shock stability. It is an excellent high temperature electrical edge material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.

Identification of fused magnesia manufacturers High purity magnesia is produced by flotation purification of natural super grade magnesite ore through light burning, fine grinding, ball pressing and ultra-high temperature oil shaft kiln calcination. It is a high-quality raw material for brick making and indefinite refractory. Medium grade magnesia is produced from light burned magnesia with 97% MgO as raw material by pressing ball and calcining in high temperature shaft kiln. The product has good sintering degree and dense crystallization. It is a high-quality raw material for producing medium grade magnesia refractory products.

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
