Thermal Analysis of Strip in Multi-Bending Process after Hot Rolling

Abstract

Thermal histories in multi-bending process after hot rolling were clarified by numerical analysis. Temperature vibrates cyclically at strip surface, whereas relatively small vibration can be seen at center in thickness. Transferring speed and cooling condition characterize temperature distributions in strip thickness. In industrial production, water-cooling equipments would be necessary in order to cancel heat generation during bending deformation and maintain strip temperature in appropriate range.
