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:
A coated graphite heater. The heater has a configuration comprising a plurality of heating rungs having a major portion disposed substantially parallel to an upper surface of the heater so that the major portion is disposed horizontally. The heater configuration provides a heater that exhibits reduced thermal stress and/or reduced CTE mismatch stress particularly compared to designs having heating rungs with a major portion oriented perpendicular to the plane of the upper surface of the heater.

A system and method for repairing a blade (30) are provided. The system includes an induction heating coil configured for heating a platform (34) and slash face (72) of the blade (30). The induction heating coil extends under the platform (34) and is adjacent to the slash face (72) to provide substantially uniform localized heating to both the platform (34) and slash face (72) of the blade (30). The induction heating coil is configured so that the platform (34) is visible during a repair or welding operation.

An induction heating coil according to the present invention is formed by spirally winding an elongate laminated conductor around a coil axis, the elongate laminated conductor including a plurality of conducting layers extending in an elongate direction and a plurality of insulating layers formed between the conducting layers, each of the conducting layers being connected in parallel with one another at both ends of the elongate laminated conductor, and the conducting layers being laminated in a direction perpendicular to the coil axis around which the elongate laminated conductor is wound, wherein the elongate laminated conductor has a width (W) along the direction perpendicular to the coil axis is greater than a height (H) along the direction parallel to the coil axis. This achieves a light and inexpensive induction heating coil which is easy to be manufactured with high dimensional precision while substantially improving the cooling efficiency thereof.
