    摘要: The present invention discovers that a rolling direction force occurs even with conventional adjustment by the kiss roll state, pinpoints that the rolling direction force does not affect the roll thrust force, and thereby enables more precise initial roll gap position adjustment of a rolling mill (rolling zero adjustment).That is, this is based on the fact that high precision rolling zero adjustment becomes possible without being affected by any thrust force acting between rolls if performing differential asymmetrical roll gap zero point adjustment of the work side and the drive side so that the difference of the rolling direction forces acting on the roll chocks of the work side and the drive side of the work roll at the work side and the drive side (in practice, within ±5% of the sum of the rolling direction forces at the work side and the drive side).

    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.
