Measuring method, measuring system and electronic equipment for intersecting angle of work rolls of rolling mill

Abstract

The invention discloses a method for measuring the cross angle of work rolls of a rolling mill. The overall idea is as follows: when strip steel is rolled, the rolling force F received by the upper work roll under the action of strip steel is determined. 1上 , the rolling force F of the lower work roll under the action of the strip 1下 ;Determine the axial force F on the drive shaft of the upper work roll a上 , the axial force F on the drive shaft of the lower work roll a下 ; according to the rolling force F 1上 and axial force F a上 , determine the angle b between the upper work roll and the transverse direction of the strip 上 ; according to the rolling force F 1下 and axial force F a下 , determine the angle b between the lower work roll and the transverse direction of the strip 下 ; according to b 上 and b 下 , to determine the cross angle between the upper work roll and the lower work roll; the above measurement method can timely evaluate the deviation of the upper and lower work rolls by dynamically determining the cross angle value of the upper and lower work rolls in real time, so as to achieve the same thickness and reduce the thickness of the strip. The purpose of quality defects such as wave-shaped and plate-shaped.

Description

technical field [0001] The present application relates to the technical field of strip rolling, and in particular, to a measuring method, measuring system and electronic equipment for the crossing angle of work rolls of a rolling mill. Background technique [0002] For rolling mills, especially CVC rolling mills, the intersection between work rolls will inevitably occur after rolling for a period of time. The intersection between the upper and lower work rolls is the main reason for the production of the same plate difference, strip deviation, and wave shape. For this reason, the space position of the rolls must be adjusted at regular intervals. In the prior art, the distance between the rolling mill arches is usually measured. If it is greater than the specified value, a gasket is placed under the lining plate of the rolling mill bearing seat to adjust the distance between the openings. There are two problems in adopting this scheme, one is that it must be stopped for meas...
