Yingkou fused magnesia contact phone address
High purity magnesite is produced by flotation purification of natural super grade magnesite 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.

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

Compared with ceramics made from alumina, ceramics made from alumina have better high-temperature performance. In general, compared with sintered magnesia, fused magnesia has the advantages of larger grains and higher density, and can be used as high-quality raw materials for making magnesium refractory.

The fused magnesite is mainly made from magnesite ore with a content of more than 47% by melting in an electric arc furnace. The chemical indexes of fused magnesia can be divided into 6 items; 1. Magnesium oxide content; 2. Silicon dioxide content; 3. Fe2O3 content; 4. Aluminum oxide content; 5. Caustic soda; 6. Body density; The fused magnesia product has large crystal grain, compact structure, slag resistant material and good thermal shock stability. It is an excellent high temperature electrical flange material and an important raw material for making high-grade magnesia bricks, magnesia carbon bricks and amorphous refractories.
