Thyssenkrupp Steel launches ramp-up of new continuous casting line 4

With the start of trial operation and casting of the first slabs on the new continuous casting line 4 (SGA 4), Thyssenkrupp Steel has reached a significant milestone at its Bruckhausen site in Duisburg – the largest single investment project in recent decades.

"The new SGA 4 will form part of one of the most modern production networks in the European steel industry. It is a central building block in our strategy to ensure there is a bright future for efficient and sustainable steel production at the Duisburg location," says Dennis Grimm, thyssenkrupp Steel's CEO. "Equipped with high-tech automation and casting technology, the line enables high-precision, flexible and efficient slab production with significantly improved shape accuracy and surface quality. Advantages that will help our customers in their competitive environment."
According to Thyssenkrupp, the production of the first slabs is an important step on the way to taking the new plant complex fully into operation, which will be taking place step by step over the next few weeks. These include the new fully automated slab storage yard and the completely modernized hot strip mill 4 with a new preliminary line and two new walking beam furnaces.

The major project in Bruckhausen

The major project in Bruckhausen is one of the largest modernization projects in the history of thyssenkrupp Steel – and the central investment package in the 20-30 Strategy. The aim is to gear up the production processes at the Duisburg location for the future, making them more efficient and flexible, while focusing on profitable premium products in order to further expand technology and quality leadership. According to the company, this will ensure that key customer markets are served in line with their requirements.
The SGA 4 replaces the previous casting rolling line and, together with the new hot strip mill 4, forms an integrated plant network. The aim is to further expand production of high-quality steel grades with the highest standards of strength, dimensional accuracy, and surface quality – particularly for applications in electric mobility, lightweight construction, and the energy sector. For example, the slabs produced on SGA 4 are used as steel transformer plates to support the energy turnaround, and as steel dynamo plates to promote electric mobility.
