Intensification of Heat and Mass Transfer in Induction Channel Furnaces

On the basis of the formulated mathematical model for the study of electromagnetic processes in a two-phase (two-inductor) induction channel furnace, electrical losses in the metal frameworks of the furnace were calculated for vari-ous options for their sectioning. The influence of the phase angle between the voltages feeding the inductors of the fur-nace on the distribution of specific and integral losses in the frames is determined. Practical recommendations for re-ducing these losses in order to increase the efficiency of melting furnaces are presented. Ref. 5, fig. 5.

The processes of creating an electromagnetic force acting on the molten metal in the active zone of a magnetodynamic pump are studied depending on the spectral composition of the higher harmonic components of the current in the chan-nel and the induction of the magnetic flux induced by an electromagnet. The peculiarities of the regulation of the mag-nitude and direction of the resultant vector of this force, the favorable conditions of the vibrational action on the molten metal in the active zone are defined.

On the basis of mathematical modelling of electromagnetic processes, electrical losses in the metal frames of the two-inductor induction channel furnace in a wide range of specific electrical conductivity of the non-magnetic material of the frames were determined. Research was conducted for two options for sectioning the lower frame of the furnace (vertical and horizontal) and two values of the phase angle between the voltages on the inductors (0 and 180 electrical degrees). For these cases, losses in furnace frames made of ferromagnetic material (construction carbon steel and magnetic stainless steel) were also calculated. Recommendations are presented on the selection of the frame material, the sectioning option and the phase angle between the voltages, which ensure minimal electrical losses. Ref. 13, fig. 4.
