The Function Of Magnesium oxide In Silicon Steel Coatings
Silicon steel sheet is widely used for low voltage
electrical industry a kind of soft magnetic materials, is the low voltage
electrical silicon steel roll often into standard specifications of the big
piece of silicon steel sheet or orientation, overseas call high-voltage electric
porcelain plate, common to motor, generator set, power transformer,
electromagnetic energy unit, solenoid valve of the electronic components and
inductive sensors.Silicon steel sheet is divided into cold rolled steel sheet
and hot rolled steel sheet.Cold rolled steel sheet silicon steel sheet has
excellent magnetic energy along the casting and rolling, not only in the strong
magnetic field has a high saturation state of magnetic flux relative density
and low iron loss, and in the weak magnetic field also has a good magnetic (the
original permeability is large.
Magnesium oxide is generally
used in oriented steel coating, silicon steel sheet used in motor core and
transformer coil.In order to better realize the electrical on the physical
properties of transformer core, orientation of the silicon steel sheet in the
manufacturing process of silicon steel sheet has a 1200-1250 degrees for high
temperature tempering heat treatment process, in order to better the tempering
heat treatment process can make the iron metal pieces atomic structure realizes
the regular orientation, of the surface layer of silicon steel sheet with
excellent insulation film, this process be sure to use the length of the 7 days
can achieve, in such a long-term continuous high temperature, to prevent the
silicon steel sheet into iron tuo, usually in the middle of the silicon steel
sheet with coating for high temperature tempering heat treatment isolation
agent to prevent the silicon steel sheet is formed,
Magnesium oxide is normally added to this coating.Silicon steel coating
using light 98 or heavy 98 magnesium oxide or analysis of pure light magnesium
oxide as an additive, magnesium oxide in the coating filling proportion in 25%,
the key to the magnesium oxide index value is less SO4, chloride ion, iron ion,
adjustment in the 0.01%.The key is used as silicon steel manufacturing process
of continuous high temperature heat treatment tempering insulation agent,
insulating layer coating agent, dephosphorization agent in steel,
desulfurization agent.
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.
