Study on Front End Bending in Plate and Strip Rolling

This paper aims to find the head bending mechanism of strip rolling in theory.The results show that the simple symmetrical rolling process can not lead to the head bending.For asynchronous rolling,the rolling process is a complex deformation of compression,shear and bending.Because of the metal flow state and the asymmetry of the mechanical state,uneven stress produced by full backward slip made the rolling easy to bend.
