Abstract

In order to reduce the strip deviation in the practical production procedure in the continuous annealing furnace, a dynamic simulation model was built through finite element method (FEM) to conduct the quantification calculation of the effect of regular roller contour types on strip deviation. The result reveals that comparing to the flat roller, forward roller contour can prevent the strip deviation to some degree. In terms of prevention ability, double-taper roller is the strongest, single-taper roller and crown roller are less stronger; and more roller contour values raise the prevention ability. Accordingly, optimization method was applied to continuous annealing furnace, and it largely reduced accidents such as strip break and limited speed that are caused by the deviation.
