Aluminium Norf GmbH (ALUNORF) is the world’s largest integrated aluminum smelter and rolling mill at a single site. It fabricates products for high quality aluminum applications which are used for instance to make cans, lithographic sheet, automotive sheet, aluminum foils and many other specialty sheets. The facility located in Neuss near Düsseldorf includes two hot rolling lines and five cold rolling mills supplied by the German SMS group, a leading supplier for metallurgical plants.
In autumn 2012, ALUNORF launched a comprehensive modernization project for the Hot Mill 1. This rolling line was originally supplied by SMS and is in operation since 1967. ALUNORF selected SMS group as their reliable partner to modernize the hot rolling mill in three steps with the target to boost output and to further improve flexibility and the product quality:
- A major upgrade of the roughing stand
- A new edger mill
- An additional finishing mill stand.
Due to the capacity requirement of the plant, production should be affected as less as possible. This fundamental requirement was realized by a meticulous planning and by considerable utilization of regular maintenance downtimes. The intensive and trustful cooperation between ALUNORF and SMS group proved to be a key success factor.
The modernization were scheduled in three main steps over a total period of more than three years which was completed in 2016. The successful results reveal the potential for a significant optimization of the rolling process, making ALUNORF’s Hot Mill #1 fit for the requirements of the future.
