Abstract
A wet skin-pass rolling method for rolling a steel sheet by a mill while adjusting the hardness of said steel sheet through control of the rolling reduction. The method comprises determining an allowable range of reduction ratio from a predetermined desired range of hardness of the product, determining a command delivery-side sheet thickness to be obtained at the delivery side of the mill on the basis of the sheet thickness measured at the entry side of the mill, and adjusting the sheet thickness control in accordance with the command delivery-side sheet thickness.
