Wuchang fused magnesia manufacturer
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, good thermal shock stability, and magnesium content of 93-98%. Therefore, the purpose of heavy 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.

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.

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.

With the development of magnesia industry, people pay more and more attention to the use of ordinary fused magnesia, which has become an important product in industrial production. Understanding the use of magnesia is of great significance for better development of magnesia industry. Magnesia is a general term for the products of magnesite and other magnesia 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
