Abstract

A hot rolling method capable of making crystal grains finer; and a hot rolling line. Specifically, a hot rolling line for metal plates comprises a finish rolling mill, a leveler, and a cooling system which are disposed in the order mentioned toward the downstream side in the direction of conveyance of the metal plate. The hot rolling method comprises, in the hot rolling line, the steps of subjecting the metal plate, which results from completion of finish rolling applied to the metal piece, to repeated bending by the leveler, and then cooling the same.
