Abstract: In order to predict the forward slip value correctly, this article established regression model of forward slip in oval-round and round-oval pass rolling, predicted the forward slip values in ach pass in Ф12 and Ф16 round bar rolling for a factory, measured forward slip of lead rods in experimental mill using geometrical modeling method. The results showed that the model of forward slip has great practical value for proper design rolling speed, rolling schedule, thereby ensuring the continuous rolling process carried out smoothly

Abstract: This article established 3D FE model of dual-radius arc finishing groove and tangent expansion angle finishing groove using ANSYS / LS-DYNA software for Wuhan Iron and Steel plant Ф16 hot continuous bar, and analyzed metal flow pattern, stress and strain distribution of two types finishing grooves. The results show that surface stress and strain distribution of dual-radius arc finishing groove have better uniform than them of tangent expansion angle finishing groove, and dual-radius arc finishing groove ensures the stability of the rolled piece in finishing groove, improve the dimensional accuracy and surface quality of rolled finishing product.
