Paper Title:
Rolling Force Research on Cogging Rolling of H-Beam
  Abstract

Due to the complexity of H-beam’s cross section, it is difficult to calculate the rolling force and force torque accurately using classic formulas conveniently when H-beams of new size are developed. This paper describes an investigation into the reversing process of H-beam using MARC software and compares the results with rolling data from the production line. A FEM model involving in three-dimensional, elastic-plastic and thermo-mechanical coupling has been established successfully to predict multi-pass rolling process. The analysis produces outputs such as deformation rules, rolling force and the web thickening. The influence of rolling reduction, the reduction rate between the web and flange are also discussed. The indications are that there is much difference between the measurement of rolling force and the rolling force calculated by using classic formulas. The reason is that real reduction during rolling process is much more than the scheduled one. A new revised method was suggested to calculate the rolling force. The simulation results show that this new method for calculating rolling force is feasible.
