【Abstract】 This paper is to research the thickness distribution across the strip and it’s re-lationship with roll’s thermal crown in asymmetric rolling. Based on practical cold rolling production test, we calculated and analysised the roll’sthermal crown and the thickness distribution across the strip under defferent thickness reduc- tion set in asymmetric rolling process, according to the theory of roll’s thermal deformationand of roll’s elastic deformation. The calculating results are based same with that of produc-tion test. So a set of production test data and a practical engineering calculating method aswell as program, which would be useful for the cold rolling production of narrow strip bymeans of asymmetric rolling processing, are provided here.更多还原
