The Study of Forward Slip Model in Round-Oval-Round Bar Rolling

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
