Fig. 1 is please referred to, industrial smelting furnace includes for holding the furnace body 11 to fusant, for adding to what is heated to fusant
Hot device 13 and for being placed in furnace body to fusant to the first coil 12 for playing stirring action to fusant, to fusant point
It not being contacted with the fever external surface of inboard wall of furnace body and heater 13, furnace body 11 is made of heat-resisting material, in furnace body 11,
Embedded with several first coils 12, first coil 12 in furnace body 11 is separated with the insulation of furnace body 11, prevent first coil 12 with
Furnace body 11 is connected, and generates security risk, and first coil 12 is that whirlpool spirals.Heater 13 includes the second coil 133, heat preservation
Layer 132 and heater 131, heater 131 are made of conductive heat-resisting material, and heater 131 is semi open model tubular, protect
Warm layer 132 fits in 132 cavity of insulating layer that 131 cylinder inner wall of heater forms semi open model, and the upper end of insulating layer 132 is past to hang down
Straight horizontal direction extends, and covers the end face of calandria, maximum can prevent scattering and disappearing for heat, 133 spiral shell of the second coil in this way
The coil group with several the number of turns is curled up into, coil adaptation is placed in 132 cavity of insulating layer.Heater 13 is placed in the formation of furnace body 11
Cell cavity in, when smelting furnace works, the second coil 133 of heater 13 is electrically connected high-frequency alternating power supply.Pass through high-frequency alternating electricity
The electromagnetic induction of generation makes heater 131 generate heat, and carries out heat transfer heating to fusant in furnace body 11.Meanwhile toward the
One coil 12 passes to low-frequency alternating electricity, so that the object to be melted in smelting furnace generates vortex, plays the role of stirring to fusant.This
Sample treat fusant heating, while further through first coil 12 pass to low-frequency alternating electricity so that object to be melted generate vortex, make to
Heat occurs for fusant and the mixed of substance moves, and stirring is not interfere with each other with heating, is improved work efficiency.It prevents to fusant not
Necessary oxidation reduces the loss of heating energy source while saving raw material.
In conjunction with Fig. 2, a kind of industrial smelting furnace stirring means, which comprises
S11, the temperature value to fusant of detection industrial smelting furnace fever external surface；To industrial smelting furnace fever external surface
