146 - Physics-based digital twin for steel strip dynamics in industrial production lines

Who are we

ArcelorMittal is one of the world's leading steel companies. Every day, its 154,000 employees in 60 countries help build a better world with smarter steels that consume less energy and emit less carbon.

The Maizières campus

The Maizières campus is the group's largest R&D site with more than 700 employees who work daily to make steel a cutting-edge product. Coming from the best academic backgrounds, its community of researchers, made up of more than 35 nationalities, designs and industrializes new products for the automotive, packaging and construction markets. To meet the group's ambitions, the decarbonization of steel production is now one of the main drivers of research carried out on the site.

Steel strips are processed at high speed on different continuous production lines. Their behaviour is influenced by strip tension, motion and interactions with rolls and other equipment. Physical models, finite element simulations and industrial data are used to analyse these phenomena and improve line operation.

The objective of this internship is to evaluate a component-based modelling tool based on principles similar to MATLAB/Simulink. The intern will build dynamic models of different production lines or line subsystems and compare the results with industrial data, existing R&D models and finite element simulations to assess the tool’s usefulness for future R&D applications.

Internship missions:
1. Become familiar with the modelling tool and its main features and define relevant case studies with R&D specialists,
2. Build and tune dynamic models of continuous production lines (e.g. continuous annealing or cold rolling lines) or specific line subsystems,
3. Perform simulations under different operating conditions and compare the results with industrial data, existing R&D models and finite element simulations to identify the tool’s strengths and limitations.
4. Develop new models to simulate specific physical phenomena, such as strip tension, catenary behaviour, strip steering and interactions with rolls.
6. Document the results and provide recommendations for future R&D applications.
