From 24 to 26 June 2014, the Coil Winding, Insulation & Electrical Manufacturing Exhibition (CWIEME) in Berlin was the place-to-be for manufacturers of electricity generators, motors and transformers. In hall 4.1 – stand 41A11, ArcelorMittal presented its worldwide offer for the core materials for electromagnetic applications.
ArcelorMittal's product range contains a very broad spectrum of steel grades with specific magnetic properties, including:
These magnetic materials are used in domestic appliances, building industry, mechanical engineering, electrical equipment, motors and generators, and of course the automotive industry.
At CWIEME 2014, ArcelorMittal introduced its new grain oriented electrical steels products. They are manufactured in Frýdek-Místek, where one can find a state-of-the-art decarburising annealing line, a new thermo-flattening line equipped with a unique inspection system, and highly energy-efficient furnaces. It allows us to propose a new generation of improved conventional grain-oriented steels with an outstanding performance / cost ratio.
On Tuesday 24th June, Sigrid Jacobs, Portfolio Director for Electrical Steels, ArcelorMittal Global R&D, was keynote speaker on "performance improvement for transformer core design with key developments in grain-oriented electrical steel". Mrs Jacobs’s presentation, prepared together with Lode Vandenbossche and Dalibor Kajfos from ArcelorMittal, focused on the optimal material choice for different transformer types and made an in-depth analysis of a cost-effective solution for specific transformers.
