Abstract:

We have carried out experiments of annealing by pulse magnetic field. The results show that a pulse magnetic field with intensity lower than 1 T can promote magnetic induction density (B8) of grain-oriented silicon steel, while the magnetic properties deteriorate sharply when intensity is higher than 1 T. It has also been found that heating by using pulse direct current can cause the magnetic properties to deteriorate, in contrast to the traditional heating using resistance furnace. Our research shows that pulse magnetic field annealing may become an effective method to modify material structures.

Key words: grain-oriented silicon steel; pulse magnetic field; annealing; magnetic property
