Abstract
The utility model discloses a medium frequency induction furnace including a furnace wall (1), a furnace bottom (2), induction coils (3), and an electromagnetic stirring device (4). The induction coils are distributed on the furnace wall, the electromagnetic stirring device is arranged at the furnace bottom, the electromagnetic stirring device mainly includes an inductor (5) and a cooling system, the inductor is arranged at the lower part of the furnace bottom and is fixed on a fixing device (6). The medium frequency induction furnace is advantageous in that after the furnace is powered on, high-intensity magnetic lines are generated in the induction coils on the furnace wall and cut the metal materials in the induction coils, large eddy current is generated in the metal materials and flows from bottom to top, so that the mixing of steel liquid tends to be uniform; meanwhile, a magnetic field is formed after the electromagnetic stirring device is turned on, the magnetic field passes through the furnace bottom to act on the steel liquid so as to push the steel liquid to flow directionally. The electromagnetic stirring carries out non-contact stirring to metal liquid depending on electromagnetic forces, the melt cannot be polluted and the stirring is convenient and thorough, so that the temperature and the alloy content of the metal are uniform.
Description
Technical field
The utility model relates to a kind of induction furnace, specifically a kind of intermediate frequency furnace.
Background technology
The conventional electric furnace of modern metallurgical works is induction furnace, particularly intermediate frequency furnace.In actual operation, usually because of induction furnace, be heated inhomogeneous, often there will be the phenomenon of wearing stove.In this case, because the liquid steel temperature in induction furnace is high, operating personnel's danger close.
After intermediate frequency furnace energising, at the inner eddy current that produces of induction furnace, molten steel is mixed before cast.But the mixing in induction furnace is not very abundant at present, easily causes molten steel component inhomogeneous, and the inhomogeneous direct serviceability that affects iron and steel of composition, the therefore necessary uniformity that improves molten steel component.
Utility model content
The problem existing for above-mentioned prior art, the utility model provides a kind of intermediate frequency furnace, makes molten steel temperature and distributed components, and that reduces induction furnace wears heat number, reduces costs.
To achieve these goals, a kind of intermediate frequency furnace of the present utility model, comprise furnace wall, furnace bottom, induction coil and electromagnetic mixing apparatus, induction coil distributes on furnace wall, furnace bottom place arranges electromagnetic mixing apparatus, electromagnetic mixing apparatus mainly comprises inductor and cooling system, and inductor is placed on the bottom of furnace bottom, and it is fixed in fixture.
Preferably, induction coil adopts fine copper to make.
Electromagnetic mixing apparatus in the utility model also comprises infrared generator, sensor and controller.
The beneficial effects of the utility model are: after energising, in induction coil on furnace wall, produce the highdensity magnetic line of force, and cut the metal material holding in induction coil, in metal material, produce very large eddy current, the direction of eddy current is for from bottom to top, molten steel is mixed and be tending towards even, electromagnetic mixing apparatus is opened simultaneously, inductor coil on it passes into low-frequency current, produce a travelling-magnetic-field, this magnetic field is through furnace bottom, act on molten steel, in molten steel, produce induced potential and electric current, this induced potential and magnetic fields produce electromagnetic force, thereby promote molten steel directed flow, play the effect of stirring.Hence one can see that, and electromagnetic agitation is carried out noncontact stirring by electromagnetic force to metal liquid, can contaminated melt.Therefore stir conveniently, fully, make the temperature of melt and alloying component even.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is this practical working state figure;
Fig. 3 is the enlarged drawing of furnace bottom bottom.
In figure: 1, furnace wall, 2, furnace bottom, 3, induction coil, 4, electromagnetic mixing apparatus, 5, inductor, 6, fixture.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of intermediate frequency furnace of the present utility model, comprise furnace wall 1, furnace bottom 2, induction coil 3 and electromagnetic mixing apparatus 4, induction coil distributes on furnace wall 1, furnace bottom 2 places arrange electromagnetic mixing apparatus 4, electromagnetic mixing apparatus 4 mainly comprises inductor 5 and cooling system, and inductor 5 is placed on the bottom of furnace bottom 2, and it is fixed in fixture 6.
In the utility model, induction coil 3 adopts fine copper to make.In most cases, induction coil 3 adopts red copper to make, because the electric conductivity of red copper, not as the electric conductivity of fine copper, easily ruptures in use.
Operation principle: after energising, in induction coil 3 on furnace wall 1, produce the highdensity magnetic line of force, and cut 3 li of metal materials that hold of induction coil, in metal material, produce very large eddy current, the direction of eddy current is for from bottom to top, molten steel is mixed and be tending towards even, electromagnetic mixing apparatus 4 is opened simultaneously, inductor coil on it passes into low-frequency current, produce a travelling-magnetic-field, this magnetic field is through furnace bottom, act on molten steel, in molten steel, produce induced potential and electric current, this induced potential and magnetic fields produce electromagnetic force, thereby promote molten steel directed flow, play the effect of stirring.Hence one can see that, and electromagnetic agitation is carried out noncontact stirring by electromagnetic force to metal liquid, can contaminated melt.Therefore stir conveniently, fully, make the temperature of melt and alloying component even.
