INDUCTOR ARRANGEMENT FOR INDUCTION HEATING APPLICATION PARTICULARLY FOR BRAZING PRESSES

摘要

An inductor arrangement for induction heating of one or more flat circular plates of different diameters including a first set of windings always active during operation of the brazing press and a second set of windings selectively inserted in series with the first set. The first set comprises a central portion including on or more small diameter pancake coils covering the center of the plate to be heated and a peripheral portion made up of a flat annular spiral surrounding the central portion and further away from this plate than the latter. The second set comprises a flat annular spiral each of whose turns is tapped so as to insert that one or pair of turns which faces the peripheral zone of the plate to be heated in series with the first set.
