摘要： This invention is directed to a method of producing a non-oriented magnetic steel sheet involving a series of processes including performing hot rolling process on a steel slab containing no more than about 0.01 wt% C, no more than about 4.0 wt% Si, no more than about 1.5 wt% Mn, no more than about 1.5 wt% Al, no more than about 0.2 wt% P, and no more than about 0.01 wt% S, performing thereto at least one cold rolling process including an optional intermediate annealing process, and then performing a finishing annealing process. The hot rolling process further includes a step which reduces thermal irregularity formed during slab heating; this step involves maintaining a sheet bar, obtained by rough-rolling of the steel slab, at a temperature ranging from about 850 DEG to 1,150 DEG C. The hot rolling process also includes a step which promotes the growth of fine precipitated particles by applying strain to the sheet bar. Magnetic steel sheet thusly obtained possess uniform magnetic properties and thickness in the coil.
