Abstract

In the present invention a non oriented electromagnetic steel sheet having excellent productivity and high magnetic flux density is obtained inexpensively and stably by a process in which during manufacturing of a non oriented electromagnetic steel sheet by a sequence of steps in which a slab having a component composition comprising in terms of mass% 0.0050% or less of C over 3.0% to 5.0% of Si 0.10% or less of Mn 0.0010% or less of Al over 0.040% to 0.2% of P 0.0040% or less of N 0.0003% to 0.0050% of S 0.0015% or more of Ca and a total of 0.01% to 0.1% of one or both of Sn and Sb the remainder being Fe and unavoidable impurities is cast in a continuous casting machine the slab is heated and subsequently hot rolled hot rolled plate annealing is then performed and after pickling the final sheet thickness is obtained by a single cold rolling after which a finishing annealing is performed in the hot rolled plate annealing step the soaking temperature is set to 900°C to 1050°C and the cooling rate after soaking is set to 5°C/s or greater.
