The invention provides a rolling method for a flat-rolled metal material and a rolling apparatus for the method each capable of stably producing a flat-rolled metal material free from camber or having an extremely light camber. The method is a rolling method of a flat-rolled metal material executed by using a rolling mill including at least work rolls and backup rolls. The apparatus is a rolling mill for this method. A rolling direction force acting on roll chocks on the operator side and the driving, side of the work roll is measured, the difference of the rolling direction force between the operator side and the driving side is calculated and a left-right swivelling component of roll gap of the rolling mill is controlled on the basis of this difference.
A rolling method of a flat-rolled metal material, for executing rolling by using a rolling mill having at least work rolls and backup rolls for a flat-rolled metal material, comprising the steps of:
