Publication number: 20230290549Abstract: 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 steps (e.g., with annealing steps between multiple cold rolling steps); 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 step and the tension leveling, the rough rolling, or the coating process, or the customer stamping or final customer annealing. In order to achieve the desired properties for the steel sheet, stamping and final annealing is performed by the customer. 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.Type: ApplicationFiled: May 16, 2023Publication date: September 14, 2023Applicant: NUCOR CORPORATIONInventors: Theodore E.

Patent number: 6007642Abstract: The present invention is directed to a low loss motor lamination steel having a relatively low alloy content, which has a composition such that the motor lamination steel is fully ferritic at all solid temperatures. The steel preferably includes 1.20-1.40 wt. % silicon, 0.25-0.40 wt. % aluminum, 0.15-0.30 wt. % manganese and not more than 0.005 wt. % carbon. The processes for producing the fully ferritic low loss motor lamination steel include a hot band anneal followed by cold rolling, and a two-stage or double cold roll process.Type: GrantFiled: December 8, 1997Date of Patent: December 28, 1999Assignee: National Steel CorporationInventor: Eric E.
