Finite Element Simulation of Biting Process of Cold Rolling Strip for 6-High Mill

Abstract:

In this work, On the basis of software ANSYS/LS-DYNA, the strip cold rolling simulation model was established. The process from biting to rolling steady were simulated and investigated for 6-high UCM (6-high middle rolls shift type HC-mill with middle roll bender) cold mill, including the stress, stain state, and velocity field of the workpiece and rolls. The result states that the stability of Biting Process of 6-high cold mill is preferable and the impact of biting process on the roll is acceptable. The simulation regularity corresponds well with the measurements.
