Description

A kind of surface temperature uniform electromagnetic induction heating flat board
Technical field
The present invention relates to firing equipment, particularly a kind of surface temperature uniform electromagnetic induction heating flat board.
Background technology
Electromagnetic induction heating is exactly the effect utilizing the conversion between electricity, magnetic, heat energy to reach to make heating object self-heating. Electromagnetic induction heating has been widely used for industry and sphere of life, and the bent plate such as electromagnetic oven, drying plant, large-scale hull becomes The applications such as type, bearing seamless steel tube production, the quickly heating of workpiece local surfaces.The most many scholars are the most in heating The aspects such as the coupling of mechanism, theoretical modeling, 9 Cr 2 steel using electromagnetic heating, thermo parameters method have carried out a series of research, and are applied to the engineering of reality Problem, achieves good Social and economic benef@.
Electromagnetic induction heating flat board is the one in electromagnetic induction heating device, it be mainly characterized by effect on environment Little, service life is long, and maintenance cost is low, and production performance is stable, safe and reliable.But there is also that the efficiency of heating surface is low, surface temperature is equal The problems such as even property difference, it is impossible to meeting and temperature homogeneity requires high occasion, the electromagnetic induction heating in such as scientific research is put down Plate, papermaking and cardboard processing industry etc..Therefore, the improvement of electromagnetic induction heating flat board and innovate imperative.
Summary of the invention
For above-mentioned situation, for overcoming prior art defect, it is uniform that the purpose of the present invention is just to provide a kind of surface temperature Electromagnetic induction heating flat board, can effectively solve that existing equipment power consumption is big and the problem of poor temperature uniformity.
The technical scheme that the present invention solves is, a kind of surface temperature uniform electromagnetic induction heating flat board, this heating flat board Including shell, metal plate, upper thermal insulation layer, magnetic post, flux material layer, lower thermal insulation layer, induction coil and intermediate frequency power supply, shell is non- The hollow structure of the upper opening that magnetic material is made, shell inner bottom part is equipped with lower thermal insulation layer, equipped with magnetic material on lower thermal insulation layer Layer, equipped with uniform magnetic post on flux material layer, equipped with upper thermal insulation layer on magnetic post, equipped with metal plate on upper thermal insulation layer, each magnetic Induction coil it is respectively arranged with outside post.
Present configuration novelty is unique, and advantages of simple easily operates, low cost, and surface temperature uniformity is good, the efficiency of heating surface Height, energy consumption is low, is the innovation on electromagnetic induction heating flat board.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the magnetic post distribution schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the detailed description of the invention of the present invention is elaborated.
By Fig. 1, shown in 2, the present invention include shell 6, metal plate 1, upper thermal insulation layer 2, magnetic post 3, flux material layer 4, under every Thermosphere 5, induction coil 7 and intermediate frequency power supply 8, the hollow structure of the upper opening that shell 6 is made for nonmagnetic substance, shell inner bottom Portion is equipped with lower thermal insulation layer 5, equipped with flux material layer 4 on lower thermal insulation layer, equipped with uniform magnetic post 3 on flux material layer, on magnetic post equipped with Upper thermal insulation layer 2, equipped with metal plate 1 on upper thermal insulation layer, is respectively arranged with induction coil 7 outside each magnetic post.
For ensureing using effect, the cylinder that described magnetic post 3 is made for magnetic material, cylindrical diameter≤30 milli Rice, highly≤60 millimeters.
Described magnetic post 3 has uniform M row and N row, and wherein M and N is positive integer, wherein the sensing outside odd-numbered line magnetic post The winding direction of coil is that the winding direction of the induction coil outside even number line magnetic post is counterclockwise clockwise;Described magnetic post 3 For equidistantly arrangement, line-spacing and row away from equal, all≤50 millimeters;
Described induction coil 7 is to be powered by intermediate frequency power supply 8.The material of described flux material layer and magnetic post is ferrite, magnetic Material layer and magnetic post constitute closed magnetic circuit.
By said structure it can be seen that the present invention heats employing electromagnetic induction heating, below metal plate, placed M row, N Row magnetic post, the part of metal plate corresponding above each magnetic post is all themselves directly heated, and then heat is by the way of conduction of heat Arrive metal plate upper surface, make upper surface temperature raise, and make surface temperature difference be substantially reduced.The present invention can be effectively used for papermaking Occasion higher to calandria surface temperature uniformity requirement in industry and scientific research, as a example by paper-making industry, service condition is such as Following table:
Surface temperature difference It is heated to 400 DEG C of spent times Energy consumption
Tradition electromagnetic induction heating flat board 10-14℃ 55 minutes 30KW
The present invention heats flat board 2-3℃ 32 minutes 21KW
By above-mentioned situation it should be apparent that compared with prior art, there is feature highlighted below:
1, surface temperature of metal flat plate uniformity of the present invention is good, and surface temperature difference, below 3 degree, is applied to papermaking, cardboard processing etc. When temperature homogeneity requires high occasion, final finished rate and product quality significantly improve, and this is existing Electromagnetic Heating flat board institute It is beyond one's reach;
2, intermediate frequency power supply is used to heat, it is to avoid employing high frequency electric source adds thermogenetic electromagnetic radiation, and reduces cost;
3, the efficiency of heating surface is high, compared with traditional heating mode, greatly reduces energy consumption, energy-conserving and environment-protective, and economic and social benefit shows Write.
