A Study on Scheduling of Tandem Cold Rolling

This work is an attempt towards scheduling for tandem cold rolling mills with respect to damage evolution during the process. An industrial five-stand tandem mill is simulated using a three-dimensional finite element code coupled with the ductile damage criterion. The simulation results are validated using the experimental observations. The effect of reduction distribution on damage evolution through the strip is investigated and a rolling schedule is proposed in order to reduce damage evolution and consequently strip tearing occurrence.
