Electrical Steel
Off to see the Gelsenkirchen plant of ThyssenKrupp Electrical Steel. The company name might sound misleading, but it is not about steel brewed in electrical arc furnaces. It is about steel with specific magnetic characteristics that is used everywhere where steel and electricity get in touch: engines (electricity into motion), turbines (motion into electricity), transformers (electricity into electricity). Apart from permeability, central material parameters are magnetic polarization and specific core loss. R&D aims at increasing the former while decreasing the latter.
