Thyssenkrupp inspects steel coils at its dedicated coil inspection line 2 in Dortmund, Germany, to ensure high-quality standards for its products.
As part of an extensive modernisation, Unitechnik Automatisierungs GmbH has now implemented a uniform functional safety concept that covers all subsections. The Dortmund installation is of great strategic importance for thyssenkrupp Steel Europe: all steel strip undergoes a thorough inspection before leaving the facility. The purpose of the installation is to inspect steel strip for faults and defects, as well as to detect and remedy flaws. The steel strip can also be edge-trimmed, oiled and cured.
To determine the concrete modernisation needs, Unitechnik and the thyssenkrupp divisions production, maintenance and work safety, as well as the Professional Trade Association for the Wood and Metal Industries (BGHM) conducted a functional safety analysis of the technical installation. Based on this, Unitechnik developed a modernisation concept for the inspection system 2.
The concept included the implementation of electrical, mechanical and hydraulic safety devices, as well as the modernisation of the entire drive and control technology including new system visualisation.
Thyssenkrupp Steel Europe profits from the modernisation not only from shorter set-up times and a major reduction in the number of manual work steps but also from state-of-the-art functional safety technology. The modernisation has secured the long-term and efficient operation of the installation.
