Silicon steel sheets for transformers

application Details

Cold Rolled Grain Oriented Electrical Steel Sheet

Description of Silicon Steel Sheet
Transformer silicon lamination steel core is a very low carbon ferrosilicon soft magnetic alloy, generally contains 0.5 ~ 4.5% silicon. The addition of silicon can improve the resistivity and maximum permeability of iron, and reduce coerce, core loss and magnetic aging.

Application of Silicon Steel Sheet
The silicon lamination can be used to make core of transformer and motor.

Performance Requirements of Silicon Steel Sheet

The performance requirements of silicon steel are mainly as follows: (1) Low iron loss, which is the most important index of silicon steel sheet quality. Many countries have grades based on iron loss values. The lower the iron loss, the higher the grade. (2) High magnetic induction intensity (magnetic induction) under strong magnetic field, which makes the motor and transformer core volume and weight reduce, saving silicon steel, copper wire and insulation materials. (3) Smooth surface, flat and uniform thickness can improve the core filling coefficient. (4) Good punching is more important for the manufacture of micro, small motor. (5) The surface insulation film has good adhesion and weldability, which can prevent corrosion and improve the punching property. (6) Basically no magnetic aging.

Silicon steel sheet cross-cut production line
A silicon steel sheet cross-cut production line refers to a manufacturing facility or process dedicated to the production of cross-cut or slit silicon steel sheets. Silicon steel, also known as electrical steel, is used in the production of transformer cores and other electrical devices due to its excellent magnetic properties.

The cross-cut production line typically involves several stages of processing to transform large coils or rolls of silicon steel into smaller, precision-cut sheets suitable for the construction of transformer cores. Here is a general overview of the stages involved in a silicon steel sheet cross-cut production line:

Uncoiling: Large coils of silicon steel are unwound or uncoiled at the beginning of the production line. These coils may be received from a steel mill where the silicon steel is initially produced.
Cleaning and Inspection: The silicon steel surface may be cleaned to remove any contaminants, and the sheets are inspected for quality and defects.
Shearing: The uncoiled silicon steel is then passed through a shearing machine. This machine cuts the continuous coil into individual sheets or strips, often referred to as cross-cutting.
Annealing: The cut sheets may undergo an annealing process, which involves heating and then cooling the material to relieve stresses and enhance its magnetic properties.
Surface Treatment: Some silicon steel sheets may undergo surface treatments, such as coating with insulating materials or applying protective coatings to prevent oxidation.
Stacking and Packaging: The cut and processed silicon steel sheets are stacked and packaged for transportation and further use. Precision in stacking is crucial to maintain the desired magnetic properties.
Quality Control: Throughout the production line, quality control measures are implemented to ensure that the silicon steel sheets meet the required specifications and standards.
Automation and Precision Cutting: Many modern production lines incorporate automation for precise cutting and processing of silicon steel sheets, optimizing efficiency and minimizing waste.
