With the increase of China's electrical steel production, the demand for silicon steel grade magnesium oxide keeps increasing, and the traditional process of preparing magnesium oxide from dolomite has been unable to meet the market demand.
China is a country rich in brine resources, so it is more and more important to study how to utilize salt lake resources comprehensively. Silicon steel grade magnesium oxide is a coating material for the preparation of oriented silicon steel. It is mainly used in the high-temperature annealing treatment of oriented silicon steel, and plays the roles of isolating agent, insulating film layer, desulfurization, dephosphorization and so on.
In this paper, the methods, technological process, research progress and existing problems of preparing silicon-steel grade magnesium oxide are summarized, and the development direction of preparing silicon-steel grade magnesium oxide is pointed out.
Silicon steel grade magnesium oxide magnesium oxide coating of silicon steel sheet material is used in the manufacture of orientation, magnesium oxide is a kind of high value-added products, silicon steel sheet is mainly used for orientation in the process of manufacturing high temperature annealing treatment stage, play isolation agent, the effect of dephosphorization and desulfurization agent, at the same time to react with silicon on the surface of the silicon steel, form good insulating film layer.
Silicon-steel grade magnesium oxide can also be used in the manufacture of refractory crucibles, precision ceramics, special polishes, aerospace industry, electronic industry and so on.
Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.
Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.
