摘要

One of the risks in asymmetric sheet rolling is roll slippage relative to the strip, which may cause significant process disruptions. This paper presents analytical methods for assessing and preventing roll slippage, which rely on deformation zone analysis and on the control of the process parameters during the asymmetric rolling of steel strips. An analytical expression is derived that defines the onset condition for slippage as a function of the geometric and load parameters of the deformation zone. A condition for eliminating slippage by adjusting interstand tensions is also formulated. The proposed methods were validated on a continuous cold-rolling mill with asymmetric work rolls.
