Plant-wide Temperature Drop Monitoring in Run-out Table Strip Cooling Process
Since the strip transient temperature can only be measured at a few positions inside the cooling section in hot-rolled strip laminar cooling process, a new approach of monitoring strip transient temperature in cooling process is proposed. A simple and accurate state space representation is designed firstly to describe the temperature drop of strip. An Extended Kalman Filter (EKF) is designed to reconstruct the strip temperature distribution because of its simple designation. Considering coordinating the convergence rate and stability, a trade-off feed-back coefficient of EKF is chosen. The reliability of the proposed method was demonstrated by the experimentation in one steel Ltd.
