Paper Title:
Temperature Prediction of Seven-Pass Finishing Rolling of Hot Thin Strips by FEM
  Abstract

Temperature evolution is one of the important parameters of mechanical properties of thin strip products. So the ability of prediction of temperature history before processing is critical to the processing scheme of controlling rolling and controlling cooling. In this paper an integrate model of finite element method is presented for the prediction of the temperature evolution in the finishing rolling during hot strips. The model takes into account the interaction between thermal behavior and mechanical behaviors. By using the second-development method based on the commercial code thermal behavior and temperature distribution of strips through seven-pass finishing rolling are described in detail. A method for computing the mean temperature at the exit of each pass is approached. Using this method the mean temperature can be attained after each pass. In one seven-pass thin strip rolling mills the temperature at the exit after each pass is measured by the pyrometer. The measured results and the simulation results are compared. The validity of the proposed analysis model is examined. The computing results are in agreement with the measured results.
