In a significant advancement for European steel production efficiency, SMS group, a leading German plantmaker, has completed the modernization of automation systems at the coiling area of Hot Strip Mill No. 1 operated by thyssenkrupp Steel Europe in Duisburg, Germany. This project targeted the renewal of Level 1 automation and human-machine interface (HMI) systems for the mill's three downcoilers, addressing critical challenges posed by aging control platforms and the unavailability of discontinued spare parts. The upgrade positions the facility for sustained high performance and future digitalization initiatives, underscoring the ongoing commitment to technological evolution in the steel sector.

The core of the modernization involved integrating SMS group's proven **X-Pact® ProBAS** software platform alongside X-Pact® Embedded control units. These components deliver seamless, high-speed control performance essential for precise operations in hot strip milling. Complementing this, an EtherCAT real-time Ethernet network was implemented to ensure reliable communication with high-speed sensors, while standard sensors are managed via a PROFIBUS remote I/O system. These enhancements not only boost system reliability but also lay a robust foundation for advanced automation and control systems, aligning perfectly with industry demands for increased uptime and efficiency in flat steel production.

Operator interaction has been revolutionized through ergonomic operator panels and modern visualization tools, which facilitate improved user experience and streamlined fault diagnostics. This results in higher system availability, reduced downtime, and more intuitive process management—key factors for mill operators and system integrators striving to optimize production workflows. The hot strip mill, originally supplied by SMS group, produces a wide range of carbon steel flat products in various grades and dimensions, serving as a cornerstone of thyssenkrupp Steel Europe's flat steel network. Such targeted upgrades ensure that the Duisburg site remains competitive amid evolving market pressures and regulatory demands.

This project forms part of a long-term strategic partnership between SMS group and thyssenkrupp Steel Europe, characterized by staged modernizations over recent years. Notable prior efforts include the 2024 adaptation of Level 2 process automation for expanded setup options, the 2019 integration of rotary table systems with 90 drives, 2017 improvements to side guide control, and 2013 upgrades to coil transport and tracking systems. Additionally, an X-Pact® Service agreement since 2009 has been instrumental in sustaining reliable operations. Michael Wirtz, Service Manager for Flat Products Solutions at SMS group, emphasized that their lifecycle service approach guarantees automation systems remain cutting-edge, supporting efficient and stable hot strip mill performance.

From a business perspective, this automation upgrade exemplifies how technology providers are enabling steelmakers to tackle operational inefficiencies and prepare for Industry 4.0 integration. For equipment suppliers and engineering firms, it highlights the value of modular, scalable solutions like X-Pact® that minimize disruption during upgrades. Steelmakers benefit from enhanced product quality consistency, lower maintenance costs, and improved energy efficiency—critical in an era of rising sustainability mandates. The initiative also supports compliance with modern IT security standards and automation benchmarks, vital for long-term plant viability.

Looking ahead, this collaboration signals a broader trend in the European steel industry toward continuous investment in automation and control systems. As mills face pressures from global competition, environmental regulations like CBAM, and the push for green steel, such projects deliver strategic value by extending asset lifespans and boosting throughput. For stakeholders including technology providers and mill operators, this serves as a benchmark for successful modernization, promising measurable ROI through reduced operational risks and heightened productivity. The successful completion reinforces Duisburg's role as a key production hub, poised to meet future demands in strip processing and rolling with superior technological prowess.

Industry analysts note that similar upgrades across Europe are accelerating, driven by the need for preventative maintenance and non-contact measurement integrations. This not only safeguards against production halts but also aligns with R&D efforts in quality improvements and sustainability strategies. Thyssenkrupp's proactive approach positions it advantageously, potentially influencing partnerships and investment decisions region-wide.
