Maaden, Saudi Arabia

High-grade aluminum sheet for automotive applications

Joint venture Ma’aden-Alcoa has built a production plant for aluminum hot and cold strip in Ras Al Khair, Saudi Arabia. Recognizing the benefits of a single-source supplier, the company ordered the main hot and cold rolling equipment and the strip processing lines from SMS group. Included here is a single-stand cold rolling mill in CVC® plus 4-high design. It’s equipped with an innovative inline inspection line for fast and reliable inspection.

The cold rolling mill is the core element in a production line for automotive sheet. To meet the high quality demands of the automotive industry, the mill features CVC® plus, work roll bending, a multizone cooling system, and a dry strip system. Moreover, we have equipped the mill with all the control systems required for a stable and fully automatic rolling process. The overriding system is X-Pact® AluControl. Outstanding here is our new line inspection installed at the exit side. Fully automatic, the system inspects the finished strip in real time. That ensures a rapid response to any surface flaws. Furthermore, the Multi-Plate® filter and the Airwash™ system guarantee efficient and sustainable production.
