| Abstract: | To meet the requirement of high accuracy finishing temperature control during accelerated hot strip rolling,an online self-learning finishing temperature control model that combines feed-forward control with feed-back control is developed on the basis of the concept of cooling unit inter-stand.The curves of the relationship between valves' opening and flow are found.Model application shows that the model is effective in raising the accuracy of finishing temperature control. |
