发明名称 ELECTRICAL STEEL PROCESSING WITHOUT A POST COLD-ROLLING INTERMEDIATE ANNEAL.
摘要 Embodiments of the present invention comprise; annealing steel sheets (e.g., hot rolled steel sheets or thin cast strip steel); cold rolling the sheets in one or more cold rolling passes (e.g., with an annealing steep between multiple cold rolling passes); and performing one or more of tension leveling, a rough rolling, or a coating process on the sheets after cold rolling, without an intermediate annealing step between the final cold rolling pass and the tension leveling, the rough rolling, or the coating process. In order to achieve the desired properties for the steel sheet, stamping and final annealing may be performed. The new process provides an electrical steel with the similar, same, or better magnetic properties than an electrical steel manufactured using the traditional processing that utilizes an intermediate annealing step after cold rolling and before the stamping and final annealing.
