ArcelorMittal at CWIEME 2015: responding to market trends in energy efficiency

Berlin, 23 April 2015 – ArcelorMittal will participate in CWIEME 2015, the world’s leading exhibition for coil winding, insulation and electrical manufacturing held from 5 to 7 May in Berlin, to present its broad range of electrical steels and R&D capabilities in developing the electrical steels of the future.


New European energy efficiency targets coming into force in 2015 are pushing towards greater efficiency in electrical machines and transformers. In response to this evolution, ArcelorMittal provides the best low-loss [1] non-oriented [2] electrical steels on the market, a range of innovative electrical steels for the automotive market, and specific grades of grain-oriented [3] electrical steels for transformer manufacturers.

At CWIEME 2015, ArcelorMittal will present its broad range of steel grades with specific magnetic properties, used in domestic appliances, building industry, mechanical engineering, electrical equipment, motors and generators, as well as the automotive industry. These include:

  • Fully processed and semi-processed non-oriented (NO) electrical steels
  • iCARe®, a range of innovative electrical steels for the automotive market, designed to help automakers create environmentally friendly mobility solutions
  • Grain-oriented (GO) electrical steels
  • Cores of magnetic circuits

Developing the electrical steels of the future

ArcelorMittal’s research and development teams have been applying their expertise in high performance electrical steels for the last 30 years to better anticipate market needs, with specialists dedicated to the different aspects of electrical steel such as texture, structure, coatings, magnetism, mechanical behaviour including fatigue, punching and machine assembly techniques.

As a result of these R&D initiatives, ArcelorMittal is perfectly positioned to develop the next generation of low loss, high permeability electrical steels and optimize the performance of its production lines, such as its new annealing line at Saint-Chély in France, inaugurated in September 2013.

Our advanced technical support using specific software and in-house testing tools allows ArcelorMittal to help its customers to optimize the design and manufacture of their machines.

Today, ArcelorMittal is running 10 major co-engineering and co-design programmes with major producers of high efficiency electrical machines.

ArcelorMittal will be present at stand 41A11 in hall 4.1.

[1] Low level of energy dissipation

[2] Electrical steel made with a special processing to make the steel as isotropic as possible, meaning when the steel is used in motors, these will have a smooth torque. Used for motors and generators (rotating machines)

[3] Electrical steel processed in such a way that its properties and crystal orientation are developed in the rolling direction. Used in power and distribution transformers.

ArcelorMittal officially took over the assets of Lorraine Tubes in December. Four major industrial sites located in the North East of France will now join ArcelorMittal Tubular Products, that is aiming to revive the production of the sites and the marketing of their products, which should open new markets.

The Bolt Tower is a helix of 78 metres built on top of a former blast furnace of Dolní Vítkovice, in Ostrava. This tower was built with steel from ArcelorMittal Ostrava was named after Olympic champion Usain Bolt.

ArcelorMittal Méditerranée inaugurated a photovoltaic farm at its site of Fos-sur-Mer, realised in partnership with EDF Energies Nouvelles. This 15-hectare solar farm was realised by Profil du Futur, a division of ArcelorMittal Construction, who used Magnelis®, a lead product of ArcelorMittal Europe – Flat Products for solar projects.

Managing the negative temperatures is a real challenge in the construction industry in Scandinavia. ArcelorMittal Europe – Long Products' mill in Hamburg has been working with Swedish customer Hjulsbro Steel for 5 years, providing them wire rod used to reinforce concrete in low temperatures.

When they decided to build a new centre in Ricaldone, Bottovini selected a light construction clad in organic coated steel from ArcelorMittal Europe – Flat Products.

DUO is a new real-estate development which opened its doors today in Singapore. This high rise has 2,082 tonnes of HISTAR® steel sections in its foundations, with the steel produced by ArcelorMittal Europe – Long Products.

Paris, January 4, 2018 - The Commercial Court of Bordeaux has confirmed ArcelorMittal will take over the assets of Exosun, a company that specializes in trackers for solar farms.
