Description
Technical field
The utility model belongs to firing equipment, relates to the electromagnetic high-temperature heating system.
Background technology
In the prior art, when utilizing electromagnetic induction heating that materials such as stainless steel, copper are heated, exist efficient not high, need to use reach a high temperature temperature even problem such as can not heat of difficulty of more high-power, heating-up temperature.And utilize electromagnetic induction heating to materials such as irony heating in the prior art, when temperature reaches Curie point, during the ferrous material loss of excitation, temperature is difficult to toward rising again, even can not heat again.For the nonmetal material that waits no magnetic conductivity, prior art can not be carried out the electromagnetism heating to it.
For this reason, need provide a kind of electromagnetic high-temperature heating system.
Summary of the invention
The purpose of this utility model is to provide a kind of electromagnetic high-temperature heating system, and its electric conversion efficiency height, firing rate are fast, intensification temperature height, heating-up time are short, applied widely.
For achieving the above object, the utility model adopts following technical scheme:
The electromagnetic high-temperature heating system is characterized in that: comprise graphite material layer, insulating and heater coil; Described graphite material layer is nested in to be heated external and be close to described surface to be heated; Described insulating is wrapped in described graphite material layer outer surface and closely contacts with described graphite material layer; Described heater coil is arranged on outside the described insulating.
Preferably, the cross section of described body to be heated is circle or ellipse or polygon, and described heater coil is wrapped on the described insulating; Described graphite material layer forms the cavity adaptive with described body to be heated, and described graphite material layer is nested in wall external and described cavity to be heated and is close to described surface to be heated.
Preferably, described body to be heated is flat sheet, and correspondingly described graphite material layer is tabular and setting and is close to described body to be heated bottom; Described heater coil forms tabular, and is close to the surface that does not contact with described graphite material layer of described insulating.
The beneficial effects of the utility model are: utilize the magnetic field induction vortex principle, when load coil has alternating current to pass through, produce countless magnetic confining fields, when magnetic field magnetic line passes through graphite material, at the countless little eddy current of the inner generation of graphite material, make its heating fast voluntarily, graphite is passed to heat the calandria of metal such as stainless steel, copper, iron or non-metallic material again.The calandria temperature can reach thousands of degree, thereby makes the temperature that heating target reaches to be needed.And this system's electric conversion efficiency height, firing rate are fast, intensification temperature height, short characteristics of heating-up time.The outside edge cover graphite material layer of calandria, the external application of graphite material layer is high temperature resistant and insulation material carries out heat insulation, insulation to calandria, reduces thermal loss.Heater coil is arranged on outside the heat-insulation layer, because coil and calandria centre has heat-insulation layer to separate, so calandria and heat induced coil do not have being connected on electric, so there is not the danger of electric leakage.

Embodiment
Introduce preferred implementation of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the electromagnetic high-temperature heating system of first embodiment of the present utility model comprises graphite material layer 10, insulating 20 and heater coil 30; Graphite material layer 10 forms the cavity that adapts to body 40 to be heated, and body 40 to be heated is placed in the cavity and is close to graphite material layer 10(is the wall of cavity).In this embodiment, body 40 to be heated is cylindrical shape, and its cross section is circular, and corresponding graphite material layer 10 is the cylindrical shape for adapting to also.Certainly, when body 40 to be heated was the cylinder of circle for cross section, corresponding graphite material layer 10 is the cylindrical shape for adapting to also; As long as make graphite material layer 10 edge be enclosed within the outer surface of body 40 to be heated.
Wherein, insulating 30 is wrapped in the peripheral of graphite material layer 20 and closely contacts with graphite material layer 20; , insulation heat insulation to carry out reduce scattering and disappearing of calandria heat.Heater coil 40 is arranged on outside the insulating, is wrapped in particularly on the insulating outer surface.Because heater coil is arranged on outside the heat-insulation layer, because coil has heat-insulation layer to separate with the calandria centre, so calandria and heat induced coil do not have being connected on electric, there is not the danger of electric leakage.
In the present embodiment, when load coil 30 has alternating current to pass through, produce countless magnetic confining fields, when magnetic field magnetic line passes through graphite material layer 10, at the countless little eddy current of graphite material layer 10 inner generation, make its heating fast voluntarily, graphite material layer 10 is passed to heat the calandria 40 of metals such as stainless steel, copper, iron or non-metallic material again, this mode of heating calandria temperature can reach thousands of degree, thereby make the temperature that heating target reaches to be needed, and firing rate is fast, and is safe and reliable.
