ABB has been awarded a major contract by Primetals Technologies to help optimize production at thyssenkrupp Steel Europe’s (tkSE) Duisburg-Bruckhausen plant in Germany, using the unique and proprietary ABB Flow Control Mold electromagnetic stirring and braking technology for higher quality steel produced faster and at lower cost.
The construction of a casting rolling mill and the upgrade of an existing continuous casting plant is part of a wider project awarded to Primetals Technologies, a global leader in plant engineering for the metals industry. It is part of tkSE’s Strategy 20-30 which aims to optimize operations for the requirements of automotive customers seeking improved surfaces, thinner and high-performance steels to meet crash safety standards in the growing e-mobility market.
By using FC Mold G3 (generation 3), thyssenkrupp can prevent gas bubbles and impurities from becoming trapped in the solidifying steel as the technology will offer simultaneous stirring and braking from one fixed position on the caster. In continuous slab casting, conditions in the meniscus area of the solidifying steel are crucial to determining end-product quality and have a major impact on productivity and overall operating costs. Integrated with the caster, FC Mold uses electromagnetic fields to control meniscus flow speed and fluctuations. It enables improved process control and increased resource efficiency, requires very little maintenance and typically has a long lifespan.
With an installed base at 40 sites worldwide, performance improvements delivered by FC Mold technology are well-proven. Typically, these include 50 percent reduction in defects and up to 80 percent reduction in rejected or downgraded product. In addition, FC Mold can allow for a higher casting speed.
Thyssenkrupp is one of the world’s leading producers of carbon flat steel and drives innovation in steel and high-quality products for demanding, state-of-the-art applications. It has set itself the goal of producing three million tons of CO₂-neutral steel a year by 2030 as the industry moves towards climate-neutral steel production by 2050 in line with the UN Paris Agreement. Primetals Technologies is a pioneer and world leader in the fields of engineering, plant building, and the provision of lifecycle services for the metals industry.
