PURPOSE:To prevent the generation of full powder and to improve an operating efficiency and the leveling of shape and chamber in a heat treatment or surface treatment line for a rolling material by providing a different speed rolling mill for temper rolling and a leveler on the down stream side thereof thereby eliminating back up rolls. CONSTITUTION:The rolling material 6 subjected to the prescribed heat treatment in the heat treatment line 1 such as, for example, continuous annealing line is given tension by inlet side bridle rolls 2 and is fed to the down stream side. The material 6 is temper-rolled by the winding different speed rolling mill 3, by which the shape thereof is corrected and the surface material quality is improved. The material 6 after the temper rolling is then subjected to the leveling of the camber by the leveler 4 and is fed under the tension exerted thereto by outlet side bridle rolls 5 to the down stream side.
