Grain Oriented Electrical Steel Coil
Silicon steel, also known as silicon steel Sheet or Electrical Steel, it is a ferro -silicon soft magnetic alloy steel with very low carbon content, usually containing 0.5% to 4.5% silicon. The addition of silicon can increase the resistivity and maximum permeability of iron to reduce the coercivity, iron loss and magnetic aging.

Cold rolled electrical steel is an essential soft magnetic material used as the core material for making various electrical appliances such as motors and transformers. Electrical steel is the most commonly used soft magnetic material and is widely used in the electrical power, electronics and military industries. On one hand, it is closely related to people' production, life and other daily activities, on the other hand, it has also made great progress in adapting to the progress of the times.

Cold rolled grain oriented silicon steel
Oriented Electrical Steel Feature
1 Avoiding rust and aging:
(1) Due to slitting and punching, that broken coating film, the ruptured surface will easily rusted, particularly in summer season when the relative humidity is high. So, it needs careful package and anti-rust treatment.
(2) For having better magnetic property, Electrical steel generally was produced without temper rolling process. To avoid coil break in slitting process, it is necessary to keep coils away from long storage time.
2 Stress-relief annealing
Magnetic properties of Electrical steel coils will be deteriorated by mechanical strains when it was sheared and punched into laminations or cores. In order to relieve these stress and restore the original magnetic properties, general stress-relief annealing is necessary. The following points are observed when laminations or cores are processed to stress-relief nnealing.
(1) There are two kind of coating films to be used in CSCI Electrical steel coils and they are adapted to various annealing temperature.stress-relief is necessary to be done.
(2) The magnetic property almost was not affected by ordinary industrial cooling rate scale,but abrupt heating and cooling will make distortion in cores. However, cooling should be taken until it reaches 350˚C so that no strain will occur in material.
(3) Since decarburization and excessive oxidation will affect the deterioration of magnetic properties of steel, the atmospheric gas must be carefully controlled and the dew point must be kept low. On the other hand, the oiled grease remained during fabrication also must be removed completely, and the low carbon materials are recommended to be used in the base and cover of annealing furnace.
