Methods for Producing Non-Oriented Electric Steel and Hot Rolling a Non-Oriented Electric Steel Strip

摘要

"METHODS FOR PRODUCING UNREADIED ELECTRICAL ACTION AND HOT LAMINATING A STRAP OF UNREADIED ELECTRICAL ACTION". Non-oriented electric steels are widely used as magnetic core material in a variety of electrical devices and machinery, particularly in motors where low core loss and high magnetic permeability in all directions of the strip are desired. The present invention relates to a method for producing a non-oriented electric steel with low core loss and high magnetic permeability whereby steel is produced from a steel bath that is cast into a sheet or thin, cooled, cold rolled and / or hot rolled strip into a finished strip. The finished strip is further subjected to at least one annealing treatment in which magnetic properties are developed, making the steel strip of the present invention suitable for use in electrical machinery such as motors or transformers.
