摘要： A control method of strip travel for ensuring, in a tandem rolling operation for metal strips, stable positioning of rolled work during the rolling process including the rolling of the leading and trailing ends of the work, and a tandem rolling mill in which the method is used are disclosed. In the control method of strip travel for the tandem strip rolling equipment comprising at least two roll stands and including between the roll stands a rolled work tension measuring device having independent tension detectors on both working and driving sides and a lateral position measuring device for measuring the lateral position of rolled work, the lateral position of the rolled work at the position of the rolled work tension measuring device is detected directly or estimated from an output of the lateral position measuring device, a tension difference representing the difference between tensions actually acting on the working and driving sides of the rolled work at the position of the rolled work tension measuring device is computed from the detected or estimated lateral position and the outputs of the working-side and driving-side detectors of the rolled work tension measuring device, and the difference between screwdown settings on the working and driving sides of each roll stand is controlled aiming at reducing the tension difference to zero.

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).
