...E. Baake; B. Nacke; A. Umbrashko; A. Jakovics Experimental investigations of the turbulent flow velocities measured in the melt of experimental induction furnaces show, that beside the intensive local turbulence pulsations, macroscopic low‐frequency oscillations of the recirculated toroidal main...

...E. Baake; B. Nacke; F. Bernier; M. Vogt; A. Mühlbauer; M. Blum Comprehensive knowledge of the complicated physical behavior of the induction furnace with cold crucible (IFCC) is required to utilize the advantages of this melting aggregate in melting and casting chemically high‐reactive materials...

...H. Ghoudjehbaklou; A. Kargar Three different active power filter (APF) configurations are developed for harmonic elimination of a three‐phase electric arc furnace (EAF). Three single‐phase APF, a three‐wire APF and a four‐wire APF are developed for this purpose. A predictive control method...
