Development of a new three-stage cold rolling manufacturing technology for grain-oriented silicon steel sheets

摘要

The purpose of this paper is to present some important parameters and new results, which control various stages of the manufacturing process to obtain new grain-oriented silicon steel sheets. A three-stage cold rolling method is employed for production. The results can be used to further reduce core losses of current silicon steel sheets by additional reduction of their thicknesses or increasing the silicon content of conventional grain-oriented silicon steel sheets without problems in the cold rolling stages.
