Abstract

The invention relates to the technical field of hot continuous rough rolling, in particular to a rolling mill unit deviation rectification control method and device. The rolling mill unit deviation rectification control method comprises the steps that for a first rolling mill unit comprising a first vertical rolling mill and a first horizontal rolling mill, in the process of reciprocating rolling of band steel through the first rolling mill unit, at an odd rolling pass, according to the change of rolling force deviation of the first horizontal rolling mill, a first levelling compensation value is obtained, a roll gap of the first horizontal rolling mill is adjusted, a first deviation rectification compensation value is obtained, the center line of the first vertical rolling mill is adjusted, according to the change of the rolling force deviation of the first vertical rolling mill, a second levelling compensation value is obtained, and the roll gap of the first horizontal rolling mill is adjusted; during an even rolling pass, according to the change of the rolling force deviation of the first horizontal rolling mill, a third levelling compensation value is obtained, and the roll gap of the first horizontal rolling mill is adjusted. By the adoption of the rolling mill unit deviation rectification control method and device, crossing stereoscopic deviation is conducted on the band steel in the longitudinal direction and the transverse direction, and the deviation rectification accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of hot continuous rolling and rough rolling, in particular to a deviation correction control method and device for a rolling mill. Background technique [0002] In the traditional hot continuous rolling roughing area, it is difficult to adjust the camber deviation of the intermediate billet, and the control of the intermediate billet shape has always been the core difficulty in the control of the hot continuous roughing mill. In the traditional process, the adjustment method of the intermediate billet mainly relies on the operator to manually observe the shape deviation of the strip, and then correct the deviation. This adjustment method has low accuracy and poor flexibility, and it is difficult to achieve the desired shape effect. Stable rolling has had a severe impact. Contents of the invention [0003] In view of the above problems, the present invention is proposed to provide a method and device for d...
