Title:
圧延機及び圧延機の調整方法
Document Type and Number:
Japanese Patent JP6475894
Kind Code:
B2
Abstract:
There are provided a work-side position measurement device and a drive-side position measurement device for directly measuring positions of roll chocks in a rolling direction, and positions of upper and lower working rolls 110A, 110B and upper and lower backup rolls 120A, 120B in the rolling direction are adjusted to zero point or predetermined positions. Alternatively, a change caused in the strip wedge due to a minute crossing of the axes of working rolls 810A, 810B and backup rolls 820A, 820B is calculated, and the quantities of leveling of a work-side rolling reduction cylinder device 870A and a drive-side rolling reduction cylinder device 870B are adjusted to make the strip edge equal to or smaller than a predetermined value. With this arrangement, the bilateral asymmetry (strip wedge) of the thickness distribution of a rolled material is easily adjusted even in the event that the positions of the roll chocks in the rolling direction are changed due to wear on various components including a group of liners.
