PROBLEM TO BE SOLVED: To surely correct the shape of a steel strip without causing breakage, even in the case of a thin steel strip or in the case when yield strength of the steel strip is increased and elongation (ductility) is reduced due to work-hardening, when correcting the shape of the steel strip such as flatness by using a tension leveller. SOLUTION: The steel strip 1, after cold rolling, is subjected to heat treatment at the temperature of≥70°C and≤500°C with a heat treatment facility 10 and then the shape is corrected by the tension leveller 101.
