铝热连轧尾部跑偏控制模型及其仿真
The tail deviation of the aluminum strip hot rolling control model and its simulation
摘要
Abstract
Deviation of a strip is represented by the distance between the center of the strip and the center of a roll .For various asymmetrical factors in rolling process ,the transverse symmetry of the strip width direction under the extreme pressure gradually lost .Accompanied with rapid transverse instability evolution ,the center distance between the strip and roll will increase .Devi-ation of a strip in the hot rolling process is an important unsolved technical problem .It results in reduced productivity and in some extreme cases ,leads to strip tearing and work roll injury .Due to the lack of tension control in strip tail rolling process ,it is easy to produce deviation .For the strip deviation ,the linear regression model between rolling force differences and the amount of deviation was established ,so that the stable interval of rolling force difference was found .In the tail deviation process ,the adjustment model of controlling the roll gap differences was proposed . Through the analysis of process conditions and operating data on the industrial scene ,the tails of the rolling deviation F3 ,F4 rack deviation are more serious .Thus ,the simulation based on F3 ,F4 rack is conducted using MATLAB software to validate the accuracy of this deviation model .关键词
