Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heating method comprising: moving a coil relative to an elongated workpiece to inductively heat the workpiece continuously in a direction in which the coil is moved relative to the workpiece, the workpiece being inductively heated with a magnetic field formed by the coil to which AC power is supplied; and spraying cooling fluid including a liquid to the coil and a gap between the coil and the workpiece in a form of mist at least during a period in which the AC power is supplied to the coil. 2. The heating method according to claim 1 , wherein the coil includes a core.
