Modeling and simulation of the strip tension of the pay-off reel

Pay-off reel is the key equipment in entry of the continuous annealing line. In the continuous annealing process, strip tension is an important factor that affects the operation speed of continuous annealing line, and the appropriate strip tension is also a key factor to avoid the heat buckling and running deviation of the strip. A dynamic strip tension model of the pay-off reel is proposed. The closed loop simulation software of the strip tension control, which consists of the control simulation software and the tension model software based on the dynamic model, is established. Simulation experiments results illustrate the effectiveness of the tension model and the closed loop simulation software.
