It has also become established.

We tried an innovative method for the final annealing, that is, the operation after the final annealing, especially the coating treatment, and achieved remarkable results in reducing iron loss.

No. 8-26405 and No. 58-26405 disclose that the surface of a unidirectional silicon steel sheet after finish annealing is irradiated with a laser in a direction substantially perpendicular to the rolling direction to introduce local minute strain. It has been disclosed that magnetic domain refining is used to reduce iron loss, but in this case, even if it is effective in applications where so-called strain relief annealing is not added,
When this annealing is performed, there is a disadvantage that the local minute strain that has been painstakingly introduced is released during heating and holding, the magnetic domain width expands, and the effect of laser irradiation is lost.
