ArcelorMittal to build new e-steel unit for EV motors in France

Steel giant ArcelorMittal announced it will build a new unit at its existing site in Mardyck (North of France) to produce 220 000 tons of steel for EV motors starting in 2024.

With this 300 million euros investment, ArcelorMittal will triple the production of this type of electrical steel with specific magnetic properties due to the use of silicon.

Cores of electromagnetic devices

This specialty e-steel is used in the cores of electromagnetic devices such as motors, generators, and transformers because it reduces power loss.

It is usually manufactured in cold-rolled strips less than 2 mm thick. These strips are cut to shape to make laminations which are stacked together to form the laminated cores of transformers and the stator and rotor of electric motors.

Five new lines

In existing and available production halls, five new lines will be dedicated to producing electrical steel on the Mardyck finishing site, the company says.

These lines are an annealing-pickling line, a reversible rolling mill, a preparation line, an annealing-varnishing line, and a slitting line.

The new unit, baptized ‘Electryck’, will be close to the production sites of car manufacturers Stellantis and Renault Electricity and create 100 new jobs. By 2024-2025, Europe will face shortages of this electrical steel, the company foresees.
