Abstract

PURPOSE:To improve the magnetic flux density of a steel and also its iron loss by subjecting the hot-rolled plate of a steel containing specific proportions of C and Si to winding, heating, and cooling in order under respective specific temperature conditions. CONSTITUTION:A steel, containing 0.1% or less C and 3.5% or less Si, together with, as needed, 0.1-0.5% Al, 0.3-1.0% Mn, and 0.03-0.2% P, is hot-rolled. Then the hot-rolled steel plate is wound up at 650 deg.C or more, heated at 700 deg.C or more for 30sec or more, and then cooled to 300-500 deg.C at a cooling rate of 5 deg.C/sec or more and held in the temperature range for another 30sec or more. Then, the steel plate is subjected to a cold rolling and then to annealing at a heating rate of 100 deg.C/min or more. Thus, a nonoriented electric iron plate containing a well-controlled dispersed carbide and having a low iron loss and a high magnetic flux density can be obtained.
