Meishen Technology Company
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.
