The production process of 98 fused magnesia

FIELD OF THE INVENTION The present invention relates to a method for smelting and processing high temperature refractory materials, especially a production process method for fused magnesia. 97 fused magnesia

Magnesia is magnesium oxide, which can be prepared from minerals such as magnesite, brucite, dolomite, serpentine, and olivine. Generally, magnesite and brucite can be used as raw materials to be calcined and decomposed into magnesia, and the crystallization is different due to different calcination temperatures. Magnesium is called dead-burned magnesia, and the above two kinds of magnesia are also commonly known as light magnesia, commonly known as furnace magnesia. Fused magnesia price

At present, the technological method of producing fused magnesia is generally to use electric furnace for smelting and directly smelting magnesia ore. %) also needs to consume 80 kilograms of carbon fine rods. Relevant data ("Special Refractories", "Magnesia Technology", "High-Temperature Refractory Materials") show that the light magnesia is heated with an electric arc, which can produce cubic The crystal of the structure, that is, heavy magnesia with a melting point of 2800 ° C, that is, fused magnesia. The magnesia produced in the furnace can be recrystallized by smelting in an electric furnace to produce fused magnesia.
