چکیده
The paper is devoted to investigation of the induction system for billet heating by rotation in DC magnetic field. Induction heating of aluminium billets by rotation in DC magnetic field produced by superconductive coils is an innovative technique. The efficiency of the heater is expected to be up to 90 %. Three-dimensional numerical code based on Finite element method has been developed to investigate the innovative induction system. Independent measures for coil design to obtain required temperature distribution along the billet length have been proposed. The influence of the measures on the temperature distribution in the billet taking into account different billet lengths has been investigated.
