  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE:To control the distribution of rolled loads in the direction of plate width and to predict and control the plate crown and shape after rolling by arranging a load detecting device independently to a supporting part of each divided backup roll, further, providing a roll profile detecting device to each of all rolls other than the divided backup rolls. CONSTITUTION:An assembly of both upper and lower rolls is a mechanism supporting a work roll 1 by the divided backup rolls 2A, 2B, 2C, 3A, 3B, 3C, 3D divided into seven parts in the axial direction and a mill wherein independent load detecting devices 5, 6 are arranged on the supporting part of each divided backup roll is used. A roll profile detecting device 7 is arranged on each of all rolls other than the divided backup roll. The plate crown and shape in the time of rolling can be detected and controlled by the mill with high accuracy without time lag and automation of operation of a mill can be progressed drastically.

For this reason, it takes a long time to complete the adjustment of the work roll gap shape, and there is a problem that the rolled material that has passed through the rolling mill during the time difference is not corrected in the plate crown shape. Moreover, in the conventional rolling mill,
The distribution of the rolling load in the strip width direction between the work rolls cannot be directly detected, and therefore the distribution of the rolling load in the strip width direction cannot be adjusted with high accuracy. There is a problem that it is difficult to control the high accuracy.
