Electrically fused magnesia is a high-purity oxide formed by high temperature melting of high-quality magnesite ore in an electric arc furnace. Its main characteristics are: complete structure, dense organization, high melting point (up to 2800 ℃), stable chemical properties, high compressive strength, strong insulation, erosion resistance, and corrosion resistance. It is an important raw material for metallurgy, building materials, light industry, furnace lining, and bulk materials, as well as steel, cement, glass An indispensable and important refractory material for industries such as nonferrous metal smelting. Its main purpose is to produce auxiliary refractory materials such as high-purity fused magnesia, gunning materials, ramming materials, and special refractory bricks such as flow steel brick, magnesia brick, and magnesia chrome brick in the metallurgical refractory industry. It can also be used as refractory furnace lining in vacuum and non vacuum induction furnaces, and electric arc furnaces. It is an ideal raw material for making magnesium oxide crucibles, furnace liners, and various high-temperature bushings.
