PROBLEM TO BE SOLVED: To improve yield by a cut loss of a sheet thickness defect part by reducing sheet thickness fluctuation, and to improve processing accuracy during press molding in a user.;SOLUTION: In a tension control method of a cold rolling mill, a tension of a steel sheet between at least one stand of the cold rolling mill is measured, and when the measured tension is within the range from a lower limit to an upper limit set corresponding to a target value, tension control is not performed, and when the measured tension is out of the range from the lower limit to the upper limit, tension control is performed.;SELECTED DRAWING: Figure 6;COPYRIGHT: (C)2016,JPO&INPIT
