Definitions
- Induction heating device production line, method for inductive heating and use of a surface
- the invention relates to an induction heating device for heating a metallic material having a machine direction along which the metallic material can be moved through a working area of the induction heating device for its heating.
- the invention further relates to a production line for producing and/or processing a metallic product.
- the invention further relates to a method for inductively heating a metallic material, in which the metallic material is conveyed along a conveying plane in the conveying direction during inductive heating.
- the invention also relates to a use of an induction heating device and/or a production line and/or an induction process.
- the invention also relates to a use of a surface, in particular a horizontal surface, of a carrier part.
- EP 3 025 799 A1 discloses a rolling mill with an inductor comprising an upper and a lower induction coil.
- the inductor can be moved with an inductor carriage transversely to the material flow direction or conveying direction of a metal strip which is conveyed along a conveyor line of the rolling mill.
- the induction coils for "threading" the metal strip into the inductor can initially be moved completely out of the conveyor line of the metal strip in order to avoid a collision with the metal strip if this metal strip has a critical shape or form deviation in its head area, such as a so-called ski deformation. Once the head area has passed the working area of the induction coils on the conveyor line, the inductor moves transversely to the conveyor line back into it and the metal strip can be inductively heat treated in the working area of the inductor.
- the invention is based on the object of providing an improvement or an alternative to the prior art.
- the object is achieved by an induction heating device for heating a metallic item having a machine direction along which the metallic item can be moved through a working area of the induction heating device for heating it, wherein a capacitor device for the induction heating device comprises at least two or more capacitor units which are arranged independently of one another transversely to the machine direction so as to be displaceable towards or away from the working area.
- capacitor units of the capacitor device are arranged independently of each other across the machine direction on the work Since the capacitor units are arranged so that they can be moved towards or away from the working area, such capacitor units can be moved independently of one another, whereby the masses to be accelerated on the induction heating device can be significantly reduced.
- induction coils which are arranged to be movable relative to the metallic material for heating the latter, can be accelerated individually with less mass and thus also more quickly and thus also placed more precisely at heat sinks of the metallic material in order to be able to interact with the metallic material in a more targeted manner.
- a particular advantage is the very flexible adjustment of power density distributions on the metallic material, whereby additional positive influencing factors with regard to energy efficiency and ultimately also product quality can be achieved.
- each capacitor unit associated with an induction coil can be moved independently of one another, namely to the exact extent or exactly as required by a movement of the respective associated induction coil.
- This is not only advantageous in relation to independent or separately arranged induction coils which are arranged together on one side, i.e. the top or bottom, of the metallic material or a conveying plane thereof in the machine direction one behind the other. Rather, this is just as advantageous with regard to induction coils which are arranged opposite one another on the top and bottom of the metallic material, in particular opposite one another in pairs.
- one embodiment variant provides that a capacitor unit with an induction coil can be rigidly connected to one another in an oscillating circuit, for example arranged together on a carrier part.
- the carrier part can be arranged transversely to the machine direction so that it can be displaced towards or away from the working area.
- a capacitor unit and an induction coil are arranged on a common carrier part in order to be arranged together with the carrier part so as to be displaceable transversely to the machine direction towards the working area or away from the working area.
- a capacitor unit with an induction coil can also be flexibly connected to one another in an oscillating circuit, for example arranged independently of one another and movable relative to one another.
- the capacitor unit can also advantageously be mounted independently of the induction coil, for example on different support parts.
- the capacitor unit can follow a movement of the induction coil with a time delay, so that on the one hand the induction coil can be accelerated faster without the mass of the capacitor unit, or vice versa.
- a cable-based, flexible electrical connection device between the capacitor unit and the storage device can be made shorter, since the capacitor unit can independently lag behind or lead the induction coil. Due to a shorter electrical connection device, electrical losses can be advantageously reduced.
- a capacitor unit and an induction coil are each arranged on different support parts, wherein the support parts are mounted so as to be movable independently of one another in order to be arranged so as to be displaceable transversely to the machine direction towards the working area or away from the working area.

- An active connection between a metallic item and an alternating magnetic field of the induction coil can be brought about by longitudinal field induction and/or by transverse field induction.
- longitudinal field induction the magnetic field lines run essentially in the longitudinal direction of the metallic item.
- transverse field induction the magnetic field lines in the metallic item run essentially in a transverse direction of the metallic item, in particular in the thickness direction and/or in the width direction of the metallic item.

- the coil bearings 20A and 22A can also be driven in a compact manner with the drive device by means of which the travel modules 40A and 40B are driven, in particular by means of a hydraulically operated drive device.
- the coil bearings 20A and 22A can also have independently operable drive devices if this is preferred by the user.
- capacitor units 16A and 16B as well as induction coils 20 and 22 can be mounted independently of one another in order to be able to be advantageously moved on an induction heating device 1, 100, 200 or 300.
