摘要： This invention provides a rolling method and a rolling apparatus, for flat-rolled metal materials capable of stably producing flat-rolled metal materials not having, or having extremely little, camber. A rolling method for a flat-rolled metal material uses rolling equipment including a rolling mill and at least a pair of pinch rolls for clamping a rolled material on the exit side of the rolling mill having a mechanism in which either one, or both, of upper and lower roll assemblies have a mechanism for supporting a work roll by split backup rolls split into at least three segments in an axial direction, the split backup roll group having a construction for supporting both a vertical direction load and a rolling direction load acting on the contacting work roll and each of the split backup rolls independently having a load measuring device. The method comprises the steps of directly measuring, or calculating on the basis of a predetermined measurement value, either one, or both, of left-right balance of a rolling direction force acting on a rolled material from the pinch rolls and the left-right balance of a rolling direction force acting on the work roll of the rolling mill through the rolled material; and controlling a left-right swivelling component of a roll gap of the rolling mill on the basis of the measured value or the calculated value of the left-right balance of the rolling direction force.

摘要： A rolling method and a rolling apparatus for flat rolled metal materials stably produce flat-rolled metal having no or extremely little camber. The rolling mill having work rolls with split backup rolls supporting at least one work roll is provided with at least one pair of pinch rolls. The pinch rolls apply tension to the rolled material. The difference between the rolling direction force acting on the pinch rolls at the right and left sides is calculated. Optionally, the rolling direction force acting on the work rolls at the right and left sides is also calculated. The left-right difference of the roll gap of the work rolls is controlled as a result of the calculated difference.
