Abstract：

Workpieces are easily folded in a further reverse rolling with inappropriate adjustment of the roll gap on mid-rolling zone. The appropriate spread model of high speed wire rod on mid-rolling zone was confirmed, and roll gap adjustment limit interval was calculated under the filling holes. The reasonable FEM simulation was established according to the limit interval, and the rolling process was simulated. According to the simulation result, the deformation characteristics and metal flow situation were analyzed. The results indicate that the metal lateral deformation is too large and the wordpieces are prone to produce ears when the roll gaps exceed the adjustment values. Finally, folds on the surface are effectively reduced after a reasonable interval is applied in the practical production.
