PROBLEM TO BE SOLVED: To provide a method for producing a cold-rolled steel sheet in which uniform strain is formed on the surface, to provide a method for producing a plated steel sheet utilizing the same, and, further concretely, to provide a method for annealing a cold rolled steel sheet in which uniform strain is formed on the surface at a low production cost (by single annealing). SOLUTION: The temperature of a steel strip on and after a cooling zone composing a continuous annealing stage for a cold rolled steel sheet is controlled to the range of≥100°C, and rolling is performed at a draft of 0.2 to 2.0%. Next, the steel strip is passed through as being contacted with two or more rolls having an outer diameter of 50 to 500 nm at a contact angle of≥30°, respectively. COPYRIGHT: (C)2006,JPO&NCIPI
