Definitions
- the present invention relates to a device for parade heating, by electromagnetic induction, low and medium magnetic or non-magnetic tapes thicknesses (of the order of 0.05 to 50 millimeters). She aims more particularly a device for heating by transverse flux induction.
- heating by induction parade electromagnetic of a metal strip is achieved using windings which are arranged so as to surround the strip to be heated by creating a magnetic field parallel to the outer surface of this strip in the direction of scrolling (longitudinal flow, see Figure 1a).
- windings which are arranged so as to surround the strip to be heated by creating a magnetic field parallel to the outer surface of this strip in the direction of scrolling (longitudinal flow, see Figure 1a).
- the main drawback of this type of installation is in the fact that the loop distribution of currents induced by the magnetic flux passing through does not allow generally not achieve temperature uniformity satisfactory, especially the ends in the direction of the band width (the edges) are too much or not enough heated according to the relative dimensions of the windings and of the magnetic circuit used in relation to the width of bandaged.
- EP-A-0 667 731 which discloses an induction heater electromagnetic with transverse flux in which one makes vary the length of the windings in order to adapt the flow distribution at bandwidths.
- this document suggests making these windings by assembling two opposing J-shaped inductors that can translate freely in a direction parallel to the bandwidth.
- this device does not allow to obtain a homogeneity transverse temperature very satisfactory.
- the present invention proposes to provide an original solution in producing an induction heating device electromagnetic with transverse flux whose circuit magnetic, produced by a plurality of bars independent magnetic, adapts to the width of the strip to heat. This device thus improves thermal uniformity across the width of the heating strip.
- the invention provides a heating device by electromagnetic induction of a metal strip scrolling in a specific direction comprising at least one electric winding arranged opposite at least one of large faces of said strip in order to heat the latter by cransverse magnetic flux induction, each winding being associated with at least one magnetic circuit, each circuit being divided into a plurality of bars magnetic not coupled together and arranged parallel to the direction of travel of the strip, said strip device being characterized in that said circuit magnetic, made up of said plurality of bars, independent of each other, adapts to the width of the strip to be heated by spreading or bringing together said bars of each other, so as to adapt in continues the distribution of said magnetic flux to the dimensions characteristics of said strip.
- the electromagnetic induction heater also includes screens made of good materials electrical conductivity placed in the air gap on both sides and on the other side of the strip and on the banks of the latter, so as to optimize temperature uniformity transverse.
- the surface of the magnetic circuit which is opposite of one of the large faces of the strip to heat a profile "polar" adapted (bisinusoidal for example) by cutting out magnetic sheets constituting this circuit so as to obtain better distribution of magnetic flux, and more particularly at the edges of said strip.
- polar profile means a surface of the magnetic circuit which is curved in the three directions of space.
- the device for heating by electromagnetic induction with transverse flux includes in particular two frames 1 and 1 'magnetic respectively provided with at least one electric winding 2 and arranged face to face on the side and other of a strip 4 to be heated.
- the latter can be for example guided in the air gap defined between the circuits magnetic using rollers (not shown) and so be transferred to the heating zone. Its displacement is generally continuous during the heating process according to the invention.
- the flow magnetic generated by electrical windings 2 crosspiece the strip to be heated 4 and induces therein a current which circulates in the plane of said strip and which closes in loop at the banks.
- the windings 2 are supplied with alternating current at medium frequency (for example, of the order of 50 to 20,000 Hz about).
- This circuit consists of a plurality of magnetic strips 8 arranged in parallel to the direction of travel of the strip 4 to be heated.
- the bars 8 making up the circuit magnetic 6 are not coupled together and are arranged parallel to each other. These bars are therefore independent of each other and they are also independent of the electrical windings. In in addition, they can slide using means 10 at level of the electrical windings 2 so as to deviate or get closer to each other, the electric windings remaining fixed. So the spacing between two bars adjacent can be enlarged or shrunk, continuously, under the action of said means 10. It follows that the distribution flux can be adapted to the dimensions of the strip 4, and in particular its width (cf. FIG. 2b).
- This essential characteristic of the present invention provides not only a space heater induction adaptable to different widths of the belt to heat, but above all the thermal homogeneity obtained in the direction of the width of said strip remains optimal some or the width of it.
- the spatial positioning of the magnetic strips associated with a suitable polar profile allow to act on the circulation of induced currents and therefore to control the transverse temperature distribution.
- the means 10 for sliding, continuously, the magnetic strips 8 at the level of the electrical windings 2, but without moving the latter, are constituted in particular by at least two parallel rails 11 and 11 ′ arranged each side of the surface of strip 4 and perpendicular to the direction of movement thereof.
- These rails support a plurality of frames 12, each of these frames being fixed to at least one bar 8.
- the support for the reinforcements of two is alternated adjacent bars on the two rails 11 and 11 'so to reduce congestion when the width of the circuit magnetic 6 is minimal (case where the spacing between bars is minimal).
- the frames slide on the rails using rollers 13 or the like so independent of each other which allows a very adjustment precise, optimal and continuous width of the circuit magnetic and therefore flow distribution. So we can for example make a width of the magnetic circuit varying from 800 to 1500 millimeters.
- the spacing between two adjacent magnetic strips 8 can be adjusted manually or automatically so to obtain the desired magnetic distribution.
- screens 14 in order to optimize the homogeneity of the transverse temperature of the strip to be heated, there are screens 14 in the air gap on either side of said strip and at the banks of the latter.
- Such screens are made of material with good electrical conductivity, for example of the copper type, aluminum or silver. Their function is to adjust the flow magnetic at the edges of the strip in order to control the temperature of the edges of said strip.
- these screens are also fixed on frames 15 supported by rails via rollers or analogues so that they can be animated by a movement of translation along the width of the strip used.
- magnetic pads 16 on the frames 15 supporting the screens 14 so as to refine the distribution of magnetic flux across the width of the strip, in particular such studs make it possible to fill possible temperature heterogeneities.
- These studs magnetic 16 can be coupled to screens 15 good electrical conductivity and / or magnetic strips 8 or be arranged without screens.
- the surface of the circuit is given magnetic 6 of each armature (1, 1 ') which is opposite one of the large faces of the strip 4 a "polar" profile, adapted so as to obtain a controlled distribution of the flow magnetic generated by the electrical windings 2, in particularly at the edges of said strip.
- a short-circuited turn is added (not shown) on either side of the heating device, perpendicular to the bars of the magnetic circuit and wrapping the moving tape to reduce the fields magnetic leakage at the ends of the inductor.
- FIG. 5 represents a schematic and partial view of a bright annealing plant, for example steel stainless.
- a bright annealing plant for example steel stainless.
- Such an annealing line is arranged on a single vertical strand whose total height must not exceed 50 meters approximately.
- the heating strip 18 which is guided by rollers 19, crosses over this height, first an area heating 20 then a cooling zone 21. So known for a strip of non-magnetic steel, it enters in the heating zone at room temperature (20 ° C approximately), must come out at a temperature of 1150 ° C and then be cooled to a temperature of 100 ° C at the end of the line.
- the electromagnetic induction heater according to the invention applied to such an installation has for advantage of being able to reduce the overall height of the heating zone up to approximately 10 meters, which saves much more room for cooling and allows thus reaching a line speed of 120 meters per minute for stainless steel with a thickness of 0.5 about a millimeter.
- the present invention offers therefore multiple advantages. It allows from electromagnetic induction heater using variable width magnetic circuits create a high intensity magnetic flux for medium frequencies. This density of magnetic flux allows achieve a power density transmitted to the band at heating, higher than that of known heating means. Thanks to the characteristics of the invention, there is no magnetic material in the inter-bar spaces, unlike systems according to the prior state of the technical. In addition, the electrical efficiency of this device is superior to that of known technologies. In addition, a such a device makes it possible to obtain thermal homogeneity satisfactory across the width of the strip.
