Description
To ensure a constant high productivity and quality for the newest AHSS, Andritz developed a new generation of its Metris Advanced Furnace Control. It consists of a modular design with a newly developed cooling model and a brand new multi model predictive control.
The precise physical model for all heating and cooling sections act as virtual sensors , which gives a good insight of the temperature distribution within the furnace and acts as a huge source for Big Data.
The multi model predictive control ensures collaboration between all models to enable a constant high quality and productivity. A method to compensate the varying strip emissivity over the coil length is shown.
The system was successfully installed at a Continuous Annealing Line of SSAB, Borlänge, Sweden. The presented results show a significant increase in quality.
