Definitions
- the present invention relates to improvements made to heating inductors, in particular of metal products in strips.
- the shape of the turns of the inductor 3 is improved so as to adapt the value of the magnetic field on the edges 2 of the strip 1.
- the inductor has a so-called shape in "dog bone” so as to apply a weaker magnetic field on the edges 2 of the strip than in the center of the latter.
- the disadvantage of this known solution lies in that it can generate perfect heating only for a determined width of the metal strip 1 to be heated.
- the solution illustrated in FIG. 2 consists in deflecting the magnetic field by " implementing bars such as 5, with high permeability, these bars, possibly mobile, being positioned along the edges 2 of the strip 1.
- the correction is only perfect for a determined width of strip, which leads to the need to make the magnetic bars 5 mobile, as a function of the width of the strip to be heated. This solution is therefore not practical to implement on an industrial level.
- the present invention therefore proposes to provide another solution to this problem of overheating the edges of the bands heated by induction, this solution does not have the drawbacks of the known solutions described above and which can be implemented whatever the width of the heated strip.
- the subject of the invention is a system for the induction heating of metallic products, in particular strips, with longitudinal magnetic flux, characterized in that the inductor comprises, inside the latter, two magnetic field deflectors. whose shape and arrangement are chosen so that they mask the coils of the inductor at the edges of the strip.
- the deflectors are U-shaped whose branches cover the edges of the strip to be heated and they can be arranged over all or part of the length of the inductor.
- FIG. 3 of which is a schematic perspective view illustrating an example of non-limiting embodiment of a heating system according to the invention.
- the reference inductor 6 designates the longitudinal magnetic flux heating inductor inside which the strip 1 to be heated circulates continuously.
- two magnetic field deflectors 7 and 7 ′ are introduced inside its inductor, between its turns, as can be clearly seen in FIG. 3, which are designed and arranged so as to mask, over all or part of the length of the inductor, the turns of the latter at the edges 2 of the strip to be heated.
- These deflectors therefore constitute screens with the magnetic field of the inductor causing the banks to underheat.
- the deflectors 7 and 7 ′ are U-shaped, the branches of which cover the edges 2 of the strip 1.
- the correction made to the heating is constant whatever the width of the heated strip, which makes it possible to fix the deflectors and to allow use in industrial production of the solution provided by the invention;
- the U-shaped screens located inside the inductor can have ends which are shaped so as to increase their efficiency.
