Using new technology to improve primary aluminium production

I am optimistic and forward-leaning when it comes to the future of the primary aluminium production process, and the exciting new ways we are improving this process.

This is about utilizing best practice in all plants and across shifts, implementing new technology elements whenever we re-line and upgrade our existing plants, utilizing more automation and Industry 4.0 elements, and using digital twins in the control system of the smelter.

A digital twin is a simulation model of the electrolysis process, built on physics-based models, sensor data and advanced analytics. My company has such models implemented directly in the control system of the electrolysis cells at two of its primary aluminium production sites in Norway. The twin automatically controls temperature, alumina addition and acidity of the electrolysis cells.
