Beschreibung
Zusammenfassung:	The invention provides a heating method for induction heat-treatment of converging tube parts, which is characterized by comprising the following steps: 1) preparation of induction coil: preparing the induction coil into a flared shape capable of adapting to the external surface of the heated position of the tube part, wherein the internal diameter of the induction coil is slightly greater than the external diameter of the part, the taper degree of the induction coil is the same as that of the heated position of the part, insulation cotton is wrapped outside the induction coil, and the induction coil is connected with an induction heat treatment facility; 2) extending the heated position of the part into the induction coil, and attaching the heated position of the part to the induction coil; and 3) electrifying the induction coil to heat the part.
