Highly Resistive Cold Oriented Silicon Steel With The Small Hysteresis loss

  Silicon steel with directionality is called grain-oriented silicon steel or oriented silicon steel. Oriented silicon steel is used in transformers, and the higher the degree of orientation, the better.This is because the higher the degree of orientation, the smaller the magnetostriction (the so-called magnetostriction is the phenomenon of elongation or contraction of ferromagnetic substances when magnetized, which is the main cause of transformer noise), the better the magnetic properties of the silicon steel sheet, and the reduction of iron loss. Non-oriented silicon steel is used in the manufacture of electric motors.

   Silicon steel sheet can be divided into two types: low silicon and high silicon according to its different silicon content. Low silicon wafer silicon content is less than 2.8%, it has a certain mechanical strength, mainly used in the manufacture of motors, commonly known as motor silicon steel sheet, high silicon wafer silicon content of 2.8%-4.8%, it has good magnetic properties, but brittle, mainly used in the manufacture of transformer core, commonly known as transformer silicon steel sheet. There is no strict boundary between the two in actual use, and large motors are often manufactured with high silicon wafers.
