Verfahren und Vorrichtung zum induktiven Härten einer Kurbelwelle Die Erfindung betrifft ein Verfahren zum induktiven Härten eines Bauteils (1), wonach zu här- tende Bereiche (2, 3) des Bauteils (1) mittels wenigstens einem Induktor (4) auf eine Härtetem- peratur (H) aufgeheizt werden. Dabei sieht das erfindungsgemäße Verfahren vor, dass die zu härtenden Bereiche (2, 3) zunächst auf eine Vortemperatur (PH) und anschließend mittels des wenigstens einen Induktors (4) auf die Härtetemperatur (H) aufgeheizt werden.
摘要:
A method and apparatus for additive manufacturing that includes a material guide for directing a supply of working material. An advancement mechanism comprising one or more pistons, pushers, plungers and/or pressure regulation systems are positioned behind at least a portion of the supply of working material for advancing the working material forward. The working material is heated using an electro-magnetic heating element and the melted or molten working material is deposited from a tip positioned at an end of the material guide.

Provided is apparatus (20) for heating a portion of subsea pipeline (10). The apparatus (20) generally comprises at least one electrical conductor (22), and a deployment mechanism (24) which is configured to operatively support a length of said electrical conductor (22) in a looped manner. In addition, the deployment mechanism (24) is further configured to deploy the looped conductor (26) circumferentially about at least a portion of the pipeline (10). When the conductor (22) is connected to a suitable power supply, the looped conductor (26) is configured to operatively induce an alternating magnetic field within the portion of the pipeline (10) in order to generate heat therein through induction heating.

Méthode et système de traitement thermique par induction d'une pièce métallique sur une zone ciblée. Selon la méthode, on effectue un traitement thermique à l'aide d'un élément thermique monté sur un système robotisé qui est apte à déplacer l'élément thermique en suivant une trajectoire cyclique sur une zone ciblée de manière à chauffer la zone ciblée et à minimiser les écarts de température sur la zone ciblée.
摘要:
An induction heating system includes an induction heating head assembly configured to move relative to a workpiece. The induction heating system may also include a temperature sensor assembly configured to detect a temperature of the workpiece and/or a travel sensor assembly configured to detect a position, movement, or direction of movement of the induction heating head assembly relative to the workpiece, and to transmit feedback signals to a controller configured to adjust the power provided to the induction heating head assembly by a power source based at least in part on the feedback signals. In certain embodiments, the induction heating system may also include a connection box configured to receive the feedback signals, to perform certain conversions of the feedback signals, and to provide the feedback signals to the power source. Furthermore, in certain embodiments, the induction heating system may include an inductor stand assembly configured to hold the induction heating head assembly against the workpiece.

Die Erfindung betrifft ein Verfahren zur Demontage einer auf einen Walzenkern (2) einer Presswalze (1) aufgeschrumpften Ringbandage (3), wobei die Ringbandage unter Ausdehnung erwärmt und von dem Walzenkern abgezogen wird. Dieses Verfahren ist dadurch gekennzeichnet, dass die Ringbandage mit einer Induktionsspule (4) induktiv erwärmt wird.
摘要:
A method of making a component (C) includes: depositing a metallic powder (P) on a workplane (128); directing a beam from a directed energy source (124) to fuse the powder (P) in a pattern corresponding to a cross-sectional layer of the component (C); repeating in a cycle the steps of depositing and fusing to build up the component (C) in a layer-by layer fashion; and during the cycle of depositing and melting, using an external heat control apparatus (144, 146, 150, 154) separate from the directed energy source (124) to maintain a predetermined temperature profile of the component (C), such that the resulting component (C) has a directionally-solidified or single-crystal microstructure.
