We studied a numerical model describing electromagnetic forces that arise in a cylindrical volume of metal placed in the working area of a newly designed electromagnetic stirrer. The combined use of a complex-shaped inductor with a set of 6x6 coils and a power management system makes it possible to generate magnetic fields of almost any topology (i...

In order to precisely determine the magnesium level in a titanium reduction retort by inductive methods, many interfering influences have to be considered. By using a look-up-table method, the magnesium level can be reliably identified by taking into account the interfering effects of the titanium sponge rings forming at the walls with their unknow...

Contactless liquid metal stirring by traveling magnetic field (TMF) inductor is widely applied in modern metallurgy. The quality of stirring is an actual challenge.
