Investments for improved product quality


thyssenkrupp Steel is investing a sum in the high three-digit million range, setting the course for modernization of its production network. The goals: more capable products, increased flexibility, and a sharper customer focus.

The investments thyssenkrupp Steel has scheduled for the Duisburg, Bochum, and Dortmund sites will significantly improve the quality of the product. A completely new line consisting of continuous casting lines, a hot strip mill, a double reversing mill and an annealing-isolating line will further optimize manufacturing processes and make them even more homogeneous in the future. This applies in particular to the production of non grain oriented electrical steel and multiphase steels for the automotive industry and premium industrial applications as well for blackplate for the packaging industry. Customers’ main benefit as a result of these upgrades will be having access to steels with improved geometrical and electromagnetic properties.

The plant expansion measures described above will also lead to an increase in production capacity, which in turn will improve our ability to deliver the products as ordered and on time. In addition, the investment package underpins the company’s image as a technology and quality leader and sustainably strengthens its position in European market. The upgrades are an integral part of the company’s Steel Strategy 20–30, with its goal to focus more on profitable and growing markets that are opening up as a result of, for example, the energy transition and the expansion of electromobility. In this context, the focus is primarily on premium steel grades that are required for, among other things, efficient e-mobility solutions for motors and generators – such as powercore® Traction . Products from the premium surfaces segment, such as ZM Ecoprotect® and dual-phase steels – which are required above all in the automotive industry for constructing lightweight structural and crash-relevant components – continue to be of great importance.

Hot-dip galvanized coatings gaining in importance

Investments

The new build and upgrade of production facilities will enable thyssenkrupp Steel to meet the changing needs of the market – such as the demand for tighter tolerances and thinner and wider products – in the best possible way. In principle, the investments at the three sites are a big step on the road to achieving the climate-neutral steel production being targeted – and consequently to the ongoing transformation of thyssenkrupp Steel in general. The modernization measures are all set to be completed within the next four years.

Duisburg site

Investments in Duisburg

Continuous casting line 3

An all-new continuous casting line is planned for Duisburg-Bruckhausen. It will replace continuous casting line 1 and offer, among other things, significant metallurgical benefits that will increase our customers’ productivity and improve the surface quality of their products. Construction of the new plant is scheduled for 2024.

Continuous casting line 4 & hot strip mill 4

At the Duisburg site, the existing casting rolling line will be converted into a continuous casting line with downstream hot strip mill. The project is the largest single construction measure of the investment package. Completion and integration are scheduled for 2024. This upgrade will increase the casting and rolling capacities of the plant and improve utilization of the upstream steel mill. In addition, process-optimized plant technology based on Industry 4.0 solutions will enable the portfolio of higher-strength steels and premium surfaces to be expanded. Customers can expect significant quality improvements, more flexible slab production, and positive long-term effects on their security of supply and ability to meet deadlines.

Bochum site

Investments in Bochum

Double reversing mill

The cold strip mill on the Bochum site is to be equipped with a new double reversing mill. With its back and forth (reversing) action, the rolling mill will be able to roll particularly thin materials. These are used, for example, in the e-mobility segment and increase among other things the efficiency of electric vehicles. The new double reversing mill will strengthen thyssenkrupp Steel’s e-mobility and multiphase steel portfolios and create new future product options for customers.

Annealing and isolating line

The Bochum site will see the construction of a new annealing and isolating line. Together with the new double reversing mill, the site will be expanded to create a competence center for steels for electromobility. In particular, the site’s capabilities in the production of non grain oriented electrical steel will be expanded to best meet the increasing demand for ever thinner and high-silicon materials.

Dortmund site

Investments in Dortmund

Hot-dip coating line

The new hot-dip coating line FBA10 will being erected in Dortmund by 2022 and is scheduled to open as early as next spring. This move on the part of thyssenkrupp Steel is following the continuously growing demand trend for more hot-dip galvanized products with premium surface qualities, especially in the automotive industry. The plant, which is around 350 meters long and up to 65 meters high, will be used to produce materials for vehicle interior parts and bodyshell applications, using the established hot-dip galvanizing method and the highly innovative zinc-magnesium coating method. These methods not only save on material and cost but are also sustainable thanks to the reduced coating thickness. The automotive industry in particular will benefit from the expanded production capacities for hot-dip coated premium products from the new FBA10.
