摘要
Abstract
The steady operation of rolling mill equipment is an important guarantee to give full play to the potential capacity of the equipment and improve the quality of sheet and strip.The dynamic characteristics of the rolling mill structure are the premise to ensure the steady operation of the rolling mill.According to the analysis of the"micro-scale statically determinate"design theory,the existence of about 1 mm small gap between the roll bearing seat and the frame window column is easy to make the roll system in the static indeterminate state,and then produce the dislocation and cross between the rolls.By finite element method,the influence of clearance and offset on the support reaction at both ends of the roll is analyzed,and a hydraulic intelligent liner is designed to be installed between the mill yard and the bearing seat of the upper work roll.It is found that the root cause of the unequal support reaction at both ends of the roll is the cross angle between the back-up roll and the work roll,and the cross angle comes from the"forced"gap between the rolling mill bearing seat and the frame.By developing intelligent liner,zero gap control can be realized to ensure the stable and reliable operation of rolling rolls parallel positioning,which releases the potential of rolling mill,provides a new idea for nonlinear dynamic analysis and stability control of rolling mill,and has important guiding significance for practical production.关键词
