Good Shearing Permeability Standard Turns And Magnetic Density With Good Surface Quality Iron Core

   In the process of processing and using silicon steel sheets, the adhesion of silicon steel sheets to the insulating film is conducive to anti-corrosion and improving the punching properties of silicon steel sheets.

  The quality of silicon steel sheet depends on the material and processing technology of silicon steel sheet, it directly affects the quality of the transformer, the stamping method in the processing process, the annealing method is the most important, the performance of the transformer made of the same material silicon steel sheet with small stamping burr and large burr is 7%, and the performance difference between the transformer made of silicon steel sheet of the same material (nitrogen protection annealing) and the transformer made of non-annealed silicon steel sheet is 7-10%.
