It will be further appreciated that, the term "and/or" used in description of the invention and appended claims is
Refer to any combinations of one or more of the associated item listed and be possible to combination, and including these combinations.
Refer to Fig. 1, industrial smelting furnace include being used for holding the body of heater 11 for treating fused mass, for treat fused mass heating plus
Hot device 13 and for treating that fused mass plays the first coil 12 of stirring action, treating that fused mass is placed in body of heater, treating fused mass point
Heating external surface not with inboard wall of furnace body and heater 13 is contacted, and body of heater 11 is made up of exotic material, in body of heater 11,
Be embedded with some first coils 12, the insulation of the first coil 12 being embedded in body of heater 11 and body of heater 11 is separated, prevent first coil 12 with
Body of heater 11 is turned on, and produces potential safety hazard, and first coil 12 is spiraled for whirlpool and formed.Heater 13 includes the second coil 133, insulation
Layer 132 and heater 131, heater 131 are made up of conductive exotic material, and heater 131 is semi open model tubular, is protected
Warm layer 132 fits in the cavity of heat-insulation layer 132 of the cylinder inner wall of heater 131 formation semi open model, and the upper end of heat-insulation layer 132 is past to hang down
Straight horizontal direction extension, covers the end face of calandria, so can be maximum prevent scattering and disappearing for heat, the spiral shell of the second coil 133
The coil group with some numbers of turn is curled up into, coil adaptation is placed in the cavity of heat-insulation layer 132.Heater 13 is placed in body of heater 11 and formed
Cell cavity in, when smelting furnace works, the second coil 133 of heater 13 is electrically connected with high-frequency alternating power supply.Pass through high-frequency alternating electricity
The electromagnetic induction of generation causes heater 131 to generate heat, and to treating in body of heater 11, fused mass carries out heat transfer heating.Meanwhile, toward the
One coil 12 passes to low-frequency alternating electricity so that the thing to be melted in smelting furnace produces vortex, plays a part of stirring and treats fused mass.This
Sample treats fused mass heating, while passing to low-frequency alternating electricity further through first coil 12 so that thing to be melted produces vortex, makes to treat
