Claim Text:
1. A heating device for heating a hollow component, comprising: at least one inner induction coil penetrating the component and configured to be heated, at least one outer induction coil surrounding the component and configured to be heated, wherein the at least one inner induction coil and the at least one outer induction coil each include a circular multi-turn coil arranged coaxially with the component, and wherein the component includes an asymmetric heat profile including at least a first heatable region and a second heatable region, and wherein the first heatable region heats more quickly than the second heatable region, at least one element disposed at least one of in a first position corresponding to the first heatable region and in a second position corresponding to the second heatable region, wherein the at least one element respectively is configured to influence a magnetic field forming between the inner and the outer induction coil during the operation of the heating device, wherein the at least one element in the first position is arranged between the inner and the outer induction coils and weakens the magnetic field in the first heatable region, and the at least one element in the second position is arranged at least one of within the inner induction coil and exterior to the outer coil with respect to the component and is configured to intensify the magnetic field in the second heatable region, wherein the at least one element facilitates even heating of the asymmetric heat profile of the component in response to being in the at least one of the first position and the second position during the operation of the heating device.
