Annealing of silicon steel sheet heat treatment

- Dec 23, 2019-

Cold-rolled silicon steel sheets have many excellent properties, but these excellent properties (including magnetic permeability, iron loss, etc.) of semi-finished cold-rolled silicon steel can only be fully expressed after reasonable annealing, and the silicon steel sheet is very sharp after being punched and cut. Large plastic deformation and stress will affect the performance of silicon steel sheets, so cold rolled silicon steel sheets after punching and forming should be annealed.
