Preferably, also be provided with pot cover, the opening that is connected pot body that pot cover is adaptive.
Preferably, also be provided with radiator, radiator is provided with hollow cavity, in the adaptive hollow cavity that is arranged on radiator of pot body and coil groups.
Preferably, the pot body adopts composite plate to process.
Industrial electromagnetic smelting furnace of the present invention, the utilization electromagnetic induction principle utilizes the fuel factor of the eddy current of metal internal induction to carry out the fusion heating, owing to need not heat the pot body, has effectively reduced power consumption, has improved energy utilization rate; The heating of employing electromagnetism, the temperature around the smelting furnace is low, no flue dust, operating environment is good; Adopt circuit control system, operating procedure is simple, and melting is reliable, and heating-up temperature is even, and scaling loss is few, and metal ingredient is even; Casting quality is good, dissolves quick heating, and furnace temperature is easy to control, and productivity ratio is high; Equipment volume is little, and utilization rate is high, and it is convenient to change kind.
Description of drawings
Fig. 1 is the assembling decomposing schematic representation of electromagnetism melting of the present invention.
In conjunction with the accompanying drawing following Reference numeral of mark above that:
1-pot body, 11-pot mouth, 12-pot wall, the 13-side, the 2-coil groups, the 21-coil, the 3-panel, the 31-pot cover, the 4-radiator, the 41-radiator fan, the 42-hollow cavity, the 43-roller, 5-controls system.
The specific embodiment
The magnetic field that exchanges can produce fuel factor at the eddy current of metal internal induction, and this heating means have a lot of advantages with comparing with the fuel heating, and it is fast etc. to reach 50%-90%, firing rate like the efficiency of heating surface.Adopt the interchange of different frequency can obtain different heat penetrations, this is that strong more the closer to the matallic surface layer electric current, frequency is high more because eddy current is not equally distributed in metal, and this phenomenon is called " Kelvin effect ".
The purposes of no core type sense melt furnace is melting cast iron, steel, steel alloy and non-ferrous metals such as copper, aluminium in the industry.How much selecting of the metal quality that the frequency of used interchange will be held with the pot physical efficiency is to obtain best effect.Smelt the metal of packing into and being smelted in the pot, let the high frequency alternating current, just produced very strong eddy current in the metal of smelting, make metal molten thereby produce a large amount of heat through coil.This smelting process speed is fast, and easy control of temperature can avoid objectionable impurities to sneak in the metal of being smelted, and is particularly suited for smelting special alloy and special steel.
Below in conjunction with accompanying drawing, specific embodiments of the invention is described in detail.
As shown in Figure 1, the invention discloses a kind of industrial electromagnetic smelting furnace, comprise pot body 1 and coil 21; Pot body 1 has certain depth and thickness, and pot body 1 generally has the geometry of certain rule, like rectangular-shaped, circle etc.; Pot body 1 adopts metal material to process, and is connected with alternating current in the coil 21, and two ports of coil 21 link to each other with external power source; Thereby form a closed-loop path, coil 21 helical arrangement form the coil groups 2 with certain number of turn, and the shape and size of coil groups 2 are adaptive with the external dimensions of pot body 1; Pot wall 12 outsides that are sleeved on pot body 1 that coil groups 2 is adaptive; The volume of the pot body 1 of 2 snares of coil groups is the efficient melting space of pot body 1, that is to say, the main part of pot body 1 is all effectively covered by coil groups 2.
Further; Pot body 1 is provided with opening, and promptly the pot mouth 11, and is as shown in Figure 1; Because present embodiment is only with rectangular-shaped expression pot body 1; So a pot mouth 11 is rectangle (but the present invention is not limited to rectangle), four sides of pot mouth 11 also are provided with the side 13 that extends laterally, four lateral vertical settings of side 13 and pot wall 12.
