Gaizhou Magnesite Factory Origin Source Company
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.

Main uses of fused magnesia: fused magnesia is mainly used for auxiliary refractory materials such as gunning materials and ramming materials, electrical grade magnesia powder for flow-through bricks, magnesia bricks, magnesia chrome bricks, 97 fused magnesia, 98 fused magnesia and other special refractory bricks, and can also be used as refractory lining on vacuum and non vacuum induction furnaces and electric arc furnaces. It is an ideal raw material for making magnesia crucibles, furnace liners and various high-temperature casings.

Some enterprises and individuals in China still have a weak awareness of energy conservation. All levels should further strengthen the promotion of energy conservation concepts, so that the concept of energy conservation can be truly rooted in the hearts of the people. In this way, the consumption demand for energy-saving refractory products will increase significantly, which will be conducive to the expansion of the production scale of energy-saving refractory products and the development, improvement and promotion of energy-saving technologies.

The calcined magnesite is mainly composed of magnesite ore with a content of more than 46%. When the magnesite ore is calcined and heated in a high temperature shaft kiln to 1400-1800 ℃, Mg (CO3) is completely decomposed to generate periclase, which becomes hard reddish brown calcined magnesium with high fire resistance. It is an ideal raw material for producing unshaped refractory materials. The products are used for steel making open hearth furnace, electric furnace bottom and ramming furnace lining.
