The main selected raw material for Yingkou calcium carbide fused magnesia is 92% magnesium oxide, which 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 a high-temperature oil or coke shaft kiln. The product produced by calcination is called mid grade magnesia, which is mainly used for producing high-grade alkaline shaped or amorphous refractory materials. Its finished products are mainly used in industries such as metallurgy, building materials, non-ferrous metals, and chemical engineering. In addition, medium grade magnesia is used in metallurgy to manufacture metallurgical powder for joining the furnace bottom and wall, manufacturing slurry spraying furnace lining, and manufacturing magnesium bricks and magnesium chromium bricks; In addition to being used as a lining for the furnace bottom, it is also widely used in electrical steelmaking furnaces, heating furnaces, non-ferrous metal blowing furnaces, and rotary furnaces.

Application of calcium bicarbonate fused magnesia
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 the production of amorphous refractory materials, and its products are used for steelmaking open hearth furnaces, electric furnace bottoms, and ramming furnace linings.
