FE-based On-Line Model for Prediction of Roll Force and Forward Slip in Skin-Pass Rolling

Abstract

On-line prediction model which calculate roll force and forward slip of skin-pass was built based on the results of plane strain, elastic-plastic non-steady finite element process model.To develop on-line prediction model, we proposed the hypothetical mode of rolling, and introduced dimensionless parameters related to roll force. Using the integrated FE process model, a series of finite element simulation was conducted over the process variables, and the influence of various process conditions on non-dimensional parameters was inspected.The prediction accuracy of proposed on-line model is examined through compatision with predictions from a finite element process model over the the various process condition.
