Title:
圧延ラインの制御装置
Document Type and Number:
Japanese Patent JP6733612
Kind Code:
B2
Abstract:
To suppress a rolling warpage produced on material to be rolled in such a case that there is a plate thickness size difference (tapered thickness) between a tip part of the material to be rolled existing on the inlet side of a rolling machine and a part after it.SOLUTION: A warpage correction amount calculator 60 performs a primary judgement of the presence of a tapered thickness of material to be rolled based on a measurement value G, Gat a time t(step S2). The warpage correction amount calculator 60 performs a secondary judgement of the presence of the tapered thickness of the material to be rolled based on a measurement value G, Gat a time t(step S3). When both judgement results of the steps S2, S3 are positive, it can be judged that the material to be rolled having a tapered thickness enters into a target path. The warpage correction amount calculator 60 calculates a warpage correction amount ΔGof roll torque for suppressing production of rolling warpage caused by the tapered thickness (step S4).SELECTED DRAWING: Figure 3
