Abstract (en)
[origin: EP4094854A1] The present invention provides a method for performing temper rolling on a cold rolled steel sheet, the method being designed to prevent the occurrence of problems such as jumping; the method relates to wet temper rolling and addresses changes in a concentration of a temper rolling liquid and changes in a load, and the method is applicable to both a rolling mill with a single stand and a rolling mill with multiple stands.A method for performing temper rolling on a cold rolled steel sheet, the temper rolling including wet temper rolling, the cold rolled steel sheet being an annealed cold rolled steel sheet, the method including setting a tension T (kgf/mm<sup>2</sup>) per unit cross-sectional area of the steel sheet for the temper rolling, based on a carbon content C (mass%) of the cold rolled steel sheet.
