voestalpine implements first part of new process control system from Primetals Technologies

• First phase of modernization completed – 15 more phases to follow in the coming months
• Adoption of existing software libraries reduces testing effort and downtime
• Upgrade to improve investment security and system availability
• Modernization of complete process control system for the LD3 steel plant to run until end of 2022

Primetals Technologies is modernizing the entire process control system at voestalpine’s LD3 steel plant in Linz, Austria. In June 2022, voestalpine completed the first modernization phase. In this first part, process control systems for the three converter lines were updated.

Improving safety and availability

Updating the entire process control system will lead to improvements in both investment security for the steelworks and process automation availability. Involving more than 100 individual process control systems, the project will be completed in 16 phases and will run until the end of 2022.

The first phase of the modernization project covered control systems for the three converter lines and for the higher-level converter area. Upgrading systems for secondary metallurgy, slab treatment, and dedusting units will follow in coming phases. Before a new process control system goes into operation, a system test is carried out using a "digital twin", which is a digital test and simulation environment with all the functions of the production system.

One of the world’s largest systems

The old process control system of voestalpine’s LD3 steel plant is based on the SIMATIC PCS 7 system and possesses a large number of software libraries. Voestalpine’s process control system is one of the largest PCS 7 installations worldwide. While updating the entire control system, Primetals Technologies will take over the existing libraries. This saves time spent on extensive testing of important functions in all units and avoids long plant downtime.

Detailed documentation

The new process control system ensures the availability of electronic spare parts, improves operational reliability, and ensures long-term compatibility with the latest hardware and software. Throughout the project, detailed documentation will ensure that existing process control system certificates remain valid after the conversion.

One of the leading steel producers in Europe, voestalpine supplies steel to the automotive, electrical, and processing industries. In Linz, the steel producer operates a fully integrated steel plant with all production steps in one location: coke plant, blast furnace, steelmaking plants, hot and cold rolling mill, and galvanizing and strip coating units.
