How to distinguish the true and false of silicon steel sheet?
If it's a half finished core:1, suppliers should try to provide more core technical information, such as silicon steel sheet number, iron core weight, iron core size, core loss, etc..2. Check the appearance to see if it is standard and then verify that the data are consistent with the offer.3, finally, to test the core loss is around flexer.
If it is the raw material of silicon steel sheet:1, I do not know its brand, and the thickness of more than 0.35mm. You'd better not. Because it is likely to be a motor silicon steel sheet, or a hot rolled silicon steel sheet.2, in the regular transformer manufacturing plant, there are special silicon steel sheet inspection equipment, generally there are large quantities of silicon steel sheet into the factory, (although there is a formal certificate), but also to test. So you'd better send it to the unit with this test to test its real performance.3, and other, using this material as a small core, to detect core loss, divided by the weight of the iron core, to obtain specific power consumption (W/kg), but also to determine his performance.
