Where is the difference between medium magnesia and heavy burned magnesia?

Date of release:2018-07-13 Author: Click:

Yingkou dicalcium fused magnesia is the main choice of raw materials is 92% magnesium oxide content, magnesium oxide through the ball press, pressed into balls. The compacted spheres with the shape of 30mm and 30mm are calcined in a high temperature oil shaft kiln or a coke shaft kiln. The calcined products are called mid-grade magnesia. The mid-grade magnesia is mainly used to produce high-grade alkaline shaped or amorphous refractories. Its products are mainly used in metallurgy, building materials, non-ferrous, chemical and other industries. In addition, intermediate magnesia is used in metallurgy to make metallurgical powder for joining furnace bottom and furnace wall, making slurry spraying lining: making magnesia brick and magnesia chrome brick; besides lining for furnace bottom, it is also widely used in electric steelmaking furnace, heating furnace, non-ferrous metal blowing furnace and rotary furnace.

Two calcium fused magnesia uses

Magnesium magnesite is mainly used for calcination of magnesite with a content of more than 46%. Magnesium magnesite is completely decomposed into periclase when calcined in a high temperature shaft kiln and heated to 1400-1800 ~C. It becomes hard reddish brown magnesia with high refractoriness. It is an ideal raw material for producing unshaped refractories. The products are used in open hearth furnace, bottom of electric furnace and lining of ramming furnace.
