03/12/2025 – New, custom-designed fume exhaust system significantly reduces emissions
Primetals modernizes reversing cold mill at Arcelor Mittal
Arcelor Mittal Eisenhüttenstadt has recently awarded the provisional acceptance certificate (PAC) to Primetals Technologies following an extensive modernization of its reversing cold mill in Eisenhüttenstadt, Germany.
The mechanical scope of supply included a new strip press, a fume exhaust system, a media system, and internal mill equipment such as strip deflectors and emulsion spray headers. The project also featured an automation upgrade including a new flatness control system, auxiliary controls for the new mechanical equipment, a drive system for the new fume exhaust system, and integrated safety logic functions.
The modernization enables ArcelorMittal to achieve higher quality in silicon steel production. New flat bed and emulsion filters remove more impurities, resulting in cleaner strip surfaces. The new strip deflectors further improve the removal of water and oil from the strip, enhancing surface quality. With a tailormade design to ensure a perfect fit inside the facility, the new state-of-the-art fume exhaust system will significantly reduce emissions.
The automation upgrade prepares the mill to meet current and future market demands. The new flatness control system uses a model-based algorithm to enable precise, optimized strip shape adjustments, ensuring premium flatness quality. The mill is also ready for future hardware and software upgrades.
ArcelorMittal Eisenhüttenstadt is an integrated steel plant covering the entire steel value chain, from ironmaking and steelmaking to hot-rolling and cold-rolling. With an annual designed production capacity of up to 2.4 million tons of crude steel, the company employs about 2,650 people, making it the largest industrial development center in East Brandenburg. Founded in 1950, it produces flat steel for the automotive, home appliances, and enameling industries.
