    摘要: A rolling mill in which rolls are displaced in axial direction thereof during operation in dependence on the width, profile and the like factors of a material being rolled. A real rolling load difference is derived by removing a rolling load change components due to a moment produced upon displacement of the rolls from a difference in the rolling load between an operating side and a driving side of the rolling mill, and is utilized for correcting the rolling asymmetry.

    摘要: A work roll cross type rolling mill comprises a pair of work rolls and a pair of back-up rolls for backing up the work rolls. The back-up rolls are so arranged that their axes can be inclined within horizontal planes only to three or four specific angular positions. The work rolls are allowed to be inclined within horizontal planes with respect to the back-up rolls such that the axes of the work rolls cross the axes of the associated back-up rolls and cross each other. The nip between each the work roll and the associated back-up roll is lubricated so as to reduce axial thrust generated therebetween due to the crossing of the rolls. The cross angle between the work rolls is set and controlled during rolling operation only when the roll peripheral speed or the rolling speed is 50 m/min or higher. Advantages of work roll cross type rolling mill are fully extended to realize stable rolling without trouble so as to ensure high quality of the rolled product while achieving higher rate of operation of the mill with facilitated operation.
