    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: A hot strip rolling mill comprises a strip front-end arresting device arranged between the finishing mill and the down-coiler, and the strip front-end arresting device holds a front-end of the strip and moves from an exit of the finishing mill to the down-coiler at high speed while it gives a tension to the strip. Pinch rollers and cooling water spraying devices composing the strip cooling line are capable of moving in the upper and the lower direction with respect to the strip surface in accordance with the movement of the strip front-end arresting device. Further, the hot strip rolling mill comprises an auxiliary drive device for giving an initial acceleration to the strip front-end arresting device, and/or a strip edge portion holding device for easily transferring the front-end of the hot strip from the strip front-end arresting device to the down-coiler.
