【 摘 要 】

In continuous rail rolling by universal mill, the forward-slip coefficient is one of the most important parameters to control the rollling process. Firstly the forward-slip coefficient of the web in a single stand without tension has been proposed by considering the influencing factors as many as possible. Then the tension between two adjacent stand has been represented and the forward-slip coefficient with forward pull has been derived. Moreover, the experiments of two-stand continuous rolling of rail by universal mill has been accompolished to get the forward slip coefficient of web of rail with forward pull. The theoretical results is in agreement with the experimental data basically and approaches that well.
