Simulation and analysis of hot steel strip continuous rolling on the stream surface strip element method

Based on the stream surface strip element method (SSSEM), the numerical simulation for 1450 mm hot steel strip continuous rolling with six stands is done. The distributions of the pressure, the front tension stress, the back tension stress and the exit lateral displacement of each pass are given out. The simulated results indicate that the side surface of the rolled strip is drum shape, which is in accord with the practical situation. The distribution of the back tension stress is similar to that of the front tension stress. The computed result and the experimental result of total rolling force of each pass are rather close. The simulation examples indicate that the stream surface strip element method is a reliable engineering-computation method for simulation of the three-dimensional deformations of plate and strip rolling. Its computation amount is less, and its computation range is wider. The simulated results have the instructional meaning for charting of the process specification of hot strip continuous rolling.
