Electric driving-used non-oriented electrical steel producing from sheet blank by using complete endless strip production process and preparation method

The invention discloses electric driving-used non-oriented electrical steel producing from a sheet blank by using a complete endless strip production process and a preparation method, and belongs to the field of steel manufacturing. The preparation method comprises the following steps of (1) carrying out converter smelting and vacuum treatment; (2) carrying out continuous casting and adopting liquid core reduction; (3) carrying out hot rolling, controlling rough rolling outlet temperature, and controlling reduction distribution of rough rolling and finish rolling; (4) carrying out normalizingacid pickling; (5) carrying out cold rolling; and (6) carrying out annealing and adopting a dry gas to protect an atmosphere. Compared with the prior art, the process is reasonably designed, and the electric driving motor-used non-oriented electrical steel which has the advantages of excellent sheet shape and magnetic properties, thin specification, excellent magnetism and uniformity is thus prepared. 本发明公开了一种薄板坯全无头轧制电驱动用
