| description | The features of the combined induction device designed for
transporting, pumping or mixing aluminum alloys with the
possibility of its heating are considered. Heating is capable of
melting aluminum plugs at the start, as well as compensating
for heat losses during casting or melt mixing. The device
is one of the varieties of linear MHD machines with a core
and windings with a variable number of pole pairs and the
sequence of switching windings is determined by the algorithm
of the control unit modules. Due to the open configuration of
the magnetic circuit of the MHD inductor asymmetry of the
magnetomotive forces of the windings occurs, which leads
to a distortion of the low-frequency running magnetic field.
Evaluation of the asymmetry of the electromagnetic mode
of the shortened machines for switching on the windings of
six-zone inductors can be conveniently performed according
to the vector diagrams of magnetic fluxes. Regulation of the
force and intensity of heating of the induction MHD device is
performed by redistributing the linear current load between
the phases of the inductor or programming algorithms for
separate control of the three-phase IGBT phase modes of
the inverter operating at lower frequencies. With the correct
choice of the winding connection scheme, the proposed device provides a continuous circular raster of flows in the
cores, creating uniform traction forces and increasing the
efficiency of electromagnetic effects. |
