摘要： A method for inducing local heating in a sheet metal structure includes the step of providing a sheet metal structure to be heated. In a further step a magnetic field generator is provided and in a further step the magnetic field generator is positioned adjacent to the sheet metal structure in the area to be treated such that it forms a resonance circuit arrangement together with the sheet metal structure. In a further step at least one calibration current pulse having a specific frequency is applied to the resonance circuit arrangement in order to determine the resonance frequency of the resonance circuit arrangement. In a further step at least one power current pulse is applied to the resonance circuit arrangement with the operation frequency of the current pulse corresponding to the resonance frequency of the resonance circuit arrangement as determined by the at least one calibration current pulse.

摘要： A heating apparatus and a heating method are provided. The heating apparatus includes a coil configured to receive AC power to form a magnetic field that inductively heats a workpiece, a spray unit configured to spray cooling fluid including a liquid to the coil in a form of mist at least during a period in which the AC power is supplied to the coil. Alternatively, the spray unit may be configured to spray the cooling fluid in the form of mist to a heating target portion of the workpiece placed in the magnetic field at least during the period in which the AC power is supplied to the coil.

摘要： Electric induction heating of the edges of a slab comprising an electrically conductive, non-ferrous material is achieved with a transverse flux induction coil that comprises a pair of coil sections with the slab passing between the coil sections. The coil sections extend transversely beyond the opposing edges of the slab. Magnetic flux concentrators are positioned around regions of the coil sections that are above and below the slab. An electrically conductive compensator is inserted between each of the two opposing extended ends of the coils sections in the vicinity of an edge of the slab. Alternatively only one of the edges of the slab may be inductively heated.

摘要： Disclosed is apparatus for heating smokable material to volatilize at least one component of the smokable material. The apparatus comprises a heating zone for receiving an article, and a magnetic field generator for generating a varying magnetic field that penetrates the heating zone. The article comprises smokable material and heating material that is heatable by penetration with a varying magnetic field to heat the smokable material. The magnetic field generator comprises a magnetically permeable core and a coil. The core comprises a magnetically permeable first portion and magnetically permeable first and second arms extending from the first portion. The coil is wound around the first portion of the core. The first and second arms of the core are on different sides of the heating zone.

摘要： A fixing device includes a housing, a magnetic flux generation source, a first rotary body, a second rotary body, a first core, a second core, a shaft portion, a magnetic shielding body and an air flow generator. The shaft portion has a hollow cylindrical shape, holds the second core on a peripheral surface and includes an internal space extending in an axial direction inside. The shaft portion serves as a rotary shaft in the rotation of the second core. The air flow generator generates an air flow flowing in the internal space of the shaft portion from one end side toward the other end side in the axial direction.
