FIELD: metallurgy.
SUBSTANCE: in the continuous annealing line of steel sheets containing a heating zone, a holding zone and a cooling zone, two or more induction heating devices are arranged in series in the front half of the heating zone, and in a temperature zone where the temperature of the steel sheet between two or more induction heating devices is from 250°C to 600°C, a heating stop region of length 1-30 m or a region of slow heating with a velocity of more than 0°C/s to 10°C/sec.
EFFECT: providing uniform heating of a sheet of cold rolled electrical steel sheet shape improving the quality of steel and its magnetic properties.
