Definitions
- Induction heating device method for inductive heating, production line and use
- the invention relates to an induction heating device for heating a metallic material, comprising a coil device with at least one induction coil for inductively heating the metallic material and a machine direction in which the metallic material can be conveyed.
- the invention further relates to a method for inductively heating a metallic item, in which at least one induction coil and the metallic item are at least partially brought into overlap.
- the invention further relates to a production line for manufacturing and/or processing a metallic product, in particular a semi-finished product and/or a preliminary product and/or an intermediate product and/or a product made of iron, steel and/or a non-ferrous metal material.
- the invention further relates to uses of an induction heating device, an inductive heating method, a production line and a leveling device.
- Devices of this type for inductive heating of metallic goods are known from the state of the art. For example, there are devices whose induction coils can be moved from the side into a working area, in order to be able to cover the induction coils and the metallic material, while the respective metallic material is conveyed through the work area during its inductive heating.
- EP 3 025 799 A1 discloses a rolling mill with induction coils for the inductive heating of a metal strip, in which the induction coils can be moved into or out of the line of the metal strip using an inductor carriage, i.e. transversely to the metal strip.
- the induction coils are adjustable in relation to the metal strip.
- the invention is based on the object of providing an improvement or an alternative to the prior art.
- an induction heating device for heating a metallic material comprising a coil device with at least one induction coil for inductively heating the metallic material and a machine direction in which the metallic material can be conveyed, wherein the induction heating device has at least one leveling device, by means of which a coil side of the at least one induction coil facing the metallic material can be actively aligned with respect to the metallic material.
- the leveling device can be configured to actively align the coil side of the at least one induction coil facing the metallic item in a plane-parallel manner with respect to the metallic item.
- the leveling device can be used to avoid or compensate for disadvantageous angles of attack between the induction coil and the surface of the metallic material. whereby the metallic material can be heated much more homogeneously by the induction heating device.
- undesirable angles of attack between a coil side of the induction coil facing the metallic material and a material surface of the metallic material can be compensated, with the material surface facing the coil side.
- an inhomogeneous coil-to-surface distance especially transverse to the direction of passage or conveyance of the metallic material, and thus also a resulting inhomogeneous heating of the metallic material can be avoided or at least significantly improved.
- the leveling of the at least one induction coil according to the invention can prevent a critical angular position between the induction coil and the metallic material, whereby the risk of inhomogeneous heating of the metallic material that would otherwise result can be significantly reduced or preferably completely avoided.
- Such leveling is particularly advantageous in relation to embodiments of induction heating devices with so-called open induction coils, which are attached to a conveyor line for conveying the metallic material only on one side next to this conveyor line, but have no mechanical connection or support to a bearing point or the like on an open side of the conveyor line opposite the stop side.
- the respective induction coil is often carried by a cantilever arm part, which is arranged in particular above the conveyor line or can be temporarily arranged above the conveyor line by transverse displacement.
- the latter can tilt or incline unfavorably relative to the surface of the material (critical angle of attack), which can result in a non-constant distance between the induction coil and the surface of the material, particularly over the length of the induction coil. Since the electrical power transferred or induced by the induction coil to the metallic material is significantly influenced by this distance, a critical angle setting can result in inhomogeneous heating of the metallic material.
- Possible forces that can influence the position or location of the induction coil in relation to the metallic item can be, in addition to the gravitational force acting on the masses of the induction coil, the cantilever arm part, the relevant bearing devices or similar, also electromagnetic forces that interact with the induction coil, in particular between the induction coil and a suspension of the induction coil, between two induction coils of a coil device (e.g. Maxwell forces) and between the induction coil and the metallic item (e.g. Lorentz forces), if this metallic item is between two induction coils, for example a an upper and a lower induction coil.
- electromagnetic forces that interact with the induction coil in particular between the induction coil and a suspension of the induction coil, between two induction coils of a coil device (e.g. Maxwell forces) and between the induction coil and the metallic item (e.g. Lorentz forces), if this metallic item is between two induction coils, for example a an upper and a lower induction coil.

- a metallic good can be understood to mean any semi-finished product and/or any preliminary product and/or any intermediate product and/or any product that is electrically conductive and can therefore be heated inductively.
- leveling device in the sense of the invention describes any device by means of which an angle of attack or a critical angle of attack between an induction coil, in particular a coil side or a side surface thereof, and a surface of a metallic product can be actively avoided or actively aligned.

- the present leveling device can be constructed in different ways.
- a framework such as a cantilever arm part, on which the induction coil is arranged, can be mounted in such a way that the induction coil can be actively leveled relative to the metallic material in the sense of the invention.
- the induction heating device has a transverse support, wherein the transverse support is configured to displace the at least one induction coil transversely to the machine direction.

- the induction coil can be moved more efficiently and much more quickly with respect to the metallic material, particularly across the machine direction, using a lighter cross support.
- the latter can also have an advantageous effect on a more homogeneous inductive heat input into the metallic material, as this means that heat sinks in the metallic material can be approached and reached more quickly and can therefore be heat treated for longer. can be transported while the metallic material continues to be conveyed in the direction of the machine.
