TEMPERATURE CONTROL IN INDUCTION HEATING FORGING APPLICATIONS
Temperature is a key parameter in the industrial forging process. Induction heating is a fast, efficient and easily controllable system to have a uniform and controlled thermal profile before forging.
The possibility to have a finer control over the temperature management leads to the improvement in process, a better product quality level, and lower maintenance cost. In this paper, the pyrometer noise and unstable signal is filtered and corrected using a Kalman filter based on a numerical electro-thermal model to obtain a reliable signal for the process management.
