Abstract

See full text

When producing a non-oriented electrical steel sheet by subjecting a slab containing predetermined amounts of C, Si, Mn, Al, N, and Cr to hot rolling, hot-band annealing, cold rolling, and finishing annealing in a continuous annealing furnace, the following conditions are used: a maximum reached temperature in the finishing annealing is set to be lower than 900° C.; an average cooling rate from a temperature (maximum reached temperature—50° C.) to 500° C. in a cooling process of the finishing annealing is set to 40° C./s or higher; and a parameter ε/t defined from a plastic elongation ratio ε (%) in a rolling direction between before and after the finishing annealing and a soaking time t (s) in the finishing annealing is set to 0.10 or higher. Thus, a non-oriented electrical steel sheet is obtained.
