View Product Description

Specification EI228 thickness 0.23-0.5mm silicon steel sheet for transforme

Thickness Tolerance

The good thickness tolerance is characterized by small difference in thickness in a direction parallel to the direction of rolling, small difference in thickness in a direction perpendicular to the direction of rolling, and high lamination factor.

Processing Properties

The product is suitable for punching and cutting with excellent dimensional tolerance.

Insulation Coating

The insulation coating has small color deviation, good adhesiveness and excellent resistance to heating and corrosion with high insulation coating resistance. There are several types of insulation coating available for production. According to the test results performed by the professional inspection organizations, the contents of hazardous substances comply with all the prevailing international and domestic environment protection laws and regulations including EU RoHS and REACH regulations.

The temperature of the silicon steel sheet should not be too high or excessive during annealing. Excessively high will affect the insulation coating or bond the lamination. As for the general temperature of the silicon steel sheet, we will explain that the temperature of the generally oriented silicon steel sheet is about 800 degrees The annealing temperature of non-oriented silicon steel sheet is about 700 degrees, and the protective atmosphere in the furnace is strictly controlled to be non-oxidizing atmosphere during annealing.

The selection is based on the principle that the iron core punching sheet is not oxidized, carburized and the surface insulation coating of the electrical steel strip (silicon steel sheet) is not significantly deteriorated. Use hydrogen-nitrogen mixed gas containing 2-10% of hydrogen. The addition of a small amount of hydrogen ensures that the iron core punches are not oxidized. The dew point in the protective gas should generally be below 0 ° C.
