✦ Synopsis

A main feature of the rolling of ribbed strip is local residual deformation, which affects the pulling down of rib height when the ribbed strip is rolled. Using a 3-D "slightly-compressible" rigid visco-plastic finite element method, the hot rolling of ribbed strip is analyzed in this paper. The results show that the distribution of rib height along the width of strip is not uniform, and the pulling down of rib height increases when the reduction and thickness of base strip increase. The variation of rib height is smaller with a higher rolling temperature. If the friction factor in the backward zone increases, the rib height and forward slip increase. Friction variation is found to affect the convergence of simulation. Results of simulation from the rolling of ribbed strip and experimental values have been found to be in good agreement.
