摘要： The invention provides a method for the inductive surface layer hardening of a surface running around an annular component of a hardenable steel, which achieves uniform and uninterrupted hardening. For this purpose, a) an initial zone of the surface is surface layer hardened by it being brought to hardening temperature by means of an inductor and being quenched with a spray. b) The surface is then hardened by means of a stationarily arranged inductor arrangement and a movably arranged inductor arrangement, which each comprise a leading inductor for preheating the region of the surface covered by it, a trailing inductor offset in the direction of the initial zone for finish-heating the pre-heated region to the hardening temperature and a spray for quenching the finish-heated region, wherein the movable inductor arrangement is moved along the surface and at the same time the annular component rotates about an axis of rotation in order to move the surface to be hardened along the stationary inductor arrangement. The speed of the movable inductor arrangement along the surface is greater than its circumferential speed. c) An end zone of the surface is then hardened by the leading inductor of one of the inductor arrangements being moved temporarily in the direction of the end zone at an increased feed rate compared to its trailing inductor when the end zone is located at a certain distance from inductor arrangements such that an enlarged distance results between the leading inductor and the inductor trailing it and the leading inductor is located at the end zone by a time interval earlier, whose duration is equal to the duration required by the trailing inductor to cover the distance resulting between the trailing inductor and the leading inductor such that the at least one leading inductor arriving first at the end zone preheats the end zone until the trailing inductor is located at the end zone and finish-heats the end zone to hardening temperature. Finally, the finish-heated end zone is quenched by means of a spray.

摘要： The invention relates to a method for the inductive surface layer hardening of a surface which runs around an annular component and has an initial zone, an end zone and two intermediate zones extending between the initial zone and the end zone. The initial zone is brought to hardening temperature by an inductor and quenched by a spray. Subsequently, an inductor arrangement is moved in each case along the intermediate zone to the end zone. Each inductor arrangement includes a leading inductor for preheating the region covered by it, a trailing inductor for finish-heating the preheated region and a spray for quenching the finish-heated region. After the inductor arrangements are located at a certain distance from the initial zone, the leading inductor of at least one of the inductor arrangements is moved in the direction of the end zone at an increased feed rate compared to the trailing inductor. The leading inductor thus reaches the end zone by a time interval earlier, whose duration is equal to the duration required by the trailing inductor to overcome the distance previously resulted between said trailing inductor and the leading inductor. In the meantime, the end zone is preheated by the leading inductor that reached it. When one of the trailing inductors of the inductor arrangements has arrived in the end zone, it heats the end zone to the finished hardening temperature.

摘要： A device is provided having at least one inductor for the inductive heating of a zone formed in a metallic workpiece, which zone is adjoined by a narrow material portion which is to be protected against heating up. To enable two tracks or ways arranged next to one another to be heated simultaneously without the portion of material situated between the tracks or ways being heated throughout to this temperature in the process, the invention provides a cooling means which delivers a cooling fluid onto that material portion of the workpiece which is to be protected against heating up. The device is particularly suitable for the simultaneous inductive heating of two tracks or ways which are formed on a workpiece next to one another and at a distance from one another and which are separated by a narrow material portion.
