The beneficial effects of the utility model are: it is the coil body of rectangle that the utility model installs around the cross section that is made of one or more layers metal lenticular wire in the periphery of heating furnace, principle by electromagnetic induction heats to the raw metal in heating furnace and the stove, compare the generation of having avoided pollutant, more environmental protection with the mode of heating of combustion fuel; Compare with the mode of heating of resistance-type heating and the electromagnetic induction heating mode of use higher temperature line, have lower power consumption, for the energy-saving and emission-reduction of enterprise, sizable effect has reduced production costs.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the structural representation of coil body the first embodiment;
Fig. 3 is the structural representation of coil body the second embodiment.
Embodiment
As shown in Figure 1, a kind of electromagnetic induction heating furnace of energy-conserving and environment-protective comprises stainless casing 1, is provided with body of heater 2 in the casing 1 and installs around in the electromagnetic induction coil of body of heater 2 peripheries, be provided with thermal insulation layer 3 between body of heater 2 and the electromagnetic induction coil, this thermal insulation layer 3 is coated on body of heater 2 shells.The body of heater 2 interior raw metals of directly putting into melt, such as zinc ingot metal or aluminium ingot etc.Body of heater 2 for fear of the loss of heat, also is passed to the coil fusing that electromagnetic induction coil causes for fear of high temperature at adstante febre simultaneously, therefore is provided with thermal insulation layer 3 between body of heater 2 and electromagnetic induction coil.Normally used insulating layer material is asbestos or alumina silicate.
Electromagnetic induction coil comprises that the longitudinal section is the coil body 4 of rectangle, and coil body 4 is made of one or more layers metal lenticular wire 41, and metal lenticular wire 41 is copper strap wires.In embodiment one, the layer of metal lenticular wire has consisted of coil body 4, as shown in Figure 2.Among the embodiment two, the three-layer metal lenticular wire has consisted of coil body 4, as shown in Figure 3.The number of plies of metal lenticular wire is to determine by the intensity of the specification of metal lenticular wire and required electromagnetic field is common.Because the cross section of coil body 4 is rectangle, when raw metal is heated required electricity consumption still less, the coil body caloric value is less.
