Research and construction of tension observer model for hot continuous rolling mill

Tension observer model is the basis for realizing the mini-tension control model.An accurate forecasting method for mini-tension between hot rolling stands was presented.Taken the new tension calculation model,combined the change of rolling force arm in rolling process and according to tension equation based on elasticity distortion theory,a calculation model for dynamic tension change was designed.Then,new tension observer for hot rolling mini-tension control process was constructed and good effect was achieved in actual production application.
