Innovation and application of tail automatic pre-leveling in hot strip rolling process
In hot strip rolling process,the trend of rolling force changes during the strip throwing stage caused by rolling pieces has inherited characteristics.By pre-leveling the tail of strip throwing through rolling force deviation,the contradiction caused by insufficient or excessive leveling of the single stand can be significantly reduced,the hidden deviation during the rolling process can be improved,and automatic correction control at the tail can be carried out.The test results show that this method can effectively control the hidden deviation during the rolling process,thereby improving the stability of the precision rolling process.
