Grain-Oriented Steel Sheet for Ei Lamination Transformer Core R Silicon Steel Coil of Cold Rolled
A grain-oriented electrical steel sheet subjected to magnetic domain refining by linearly introducing strains in a direction intersecting a rolling direction of the steel sheet repeatedly with intervals in the rolling direction, wherein if a repeating interval of the strains in the rolling direction is d (mm) and, when the steel sheet is placed on a flat surface, a mean value of difference between a height from the flat surface in linear strain-introduced areas of a steel sheet surface and a height from the flat surface in intermediate points between adjacent linear strain-introduced areas is h (mm), then the ratio h/d of the h to the d is 0.0025 or more and 0.015 or less.
What are the different types of electrical steel?
Electrical steel is classified into two types: non-oriented (NO)
electrical steel and grain-oriented (GO) electrical steel. NO steel
is widely used in rotating electrical machines (e.g., motors and
generators) in which the magnetization direction is rotated in the
sheet plane.

.
The performance requirements of silicon steel are mainly:
1, low iron loss, which is the most important index of silicon steel sheet quality. Countries are graded according to iron loss, the lower the iron loss, the higher the grade.
2. The magnetic induction intensity (magnetic induction) is high under the strong magnetic field, which reduces the volume and weight of the motor and transformer core, saving silicon steel sheet, copper wire and insulating materials, etc.
3, the surface is smooth, smooth and uniform thickness, can improve the filling coefficient of the iron core.
4. Good punching performance is more important for the manufacture of micro and small motors.
5. The adhesion and weldability of the surface insulation film are good, which can prevent corrosion and improve the punching property.
