ArcelorMittal to install an annealing and coating line and a cold rolling mill in Calvert

International technology group Andritz has received an order from ArcelorMittal Calvert to supply an annealing and coating line and a cold rolling mill for its new wholly owned, state-of-the-art electrical steel production facility in Calvert, Alabama, USA.

According to Andritz, the facility will be able to produce up to 150,000 tonnes of non-grain oriented electrical steel (NOES) per year, supporting the automotive and other industries’ journey towards more sustainable transportation and industrial/commercial applications. “We recognize the importance of creating a resilient, sustainable domestic Supplik chain for this critical material,” said John Brett, CEO, ArcelorMittal North America. The lines are designed with a focus on production efficiency, strip flatness and strip surface condition to produce electrical steel of the highest quality.
The S6-high cold rolling mill can roll products up to 1650 mm wide at a maximum speed of 1000 m/min to a material thickness between 0.2–0.5 mm. Designed to the highest technological standards, it is equipped with a process model for heating, cooling, and rolling to ensure optimized, cost-effective production. The  annealing and coating line processes the cold-rolled strip into high quality NOES. The annealing furnace is electrically heated, avoiding greenhouse gas emissions generated by fossil fuels during the production process. The mathematical furnace model optimizes operation in terms of material quality and energy consumption. The scope of supply includes the design and supply of all mechanical and electrical equipment as well as supervision of installation and commissioning.
