Induktives Glühen

Moderne Induktionserwärmung bietet gegenüber herkömmlichen Erwärmungsmethoden viele Vorteile und wird gerne für Anwendungen wie Kupferrohrkrümmung benutzt beim Glühen von Metalle. Die Induktion liefert eine zuverlässige, reproduzierbare, berührungsfreie und energiesparende Erwärmungin kürzester Zeit. Ambrells Induktionsanlagen können auch sehr kleine Bereiche mit präzisen Fertigungstoleranzen erhitzen, ohne die metallurgischen Eigenschaften zu beinträchtigen oder zu verändern. Das induktive Glühen bezieht sich spezifisch auf den Vorgang, der den Werkstoff auf den weichest möglichen Punkt bringt. Die für das Induktionsglühen üblicherweise verwendeten Systeme leisten 1 bis 20 kW, je nach Werkstoff und Anwendungsanforderungen.

Annealing a copper wire connector (crimp)

The client wanted to be able to heat parts of various sizes, which was achieved with a concentrator coil. This is a new process for the client, and Ambrell's lab expertise proved very valuable when creating the process...

Annealing steel wire for a medical application

The wire achieved the targeted temperature within three seconds. By bringing their process in-house, the client will have better control over the end product. Ambrell was able to perform a free laboratory test and design a process that could enable the client to bring the process in-house in a cost efficient manner, and even connect them with an automation partner to maximize productivity

Annealing stainless steel caps for a dental application

Requirement to anneal large quantities of work-hardened crowns suggests induction for precise, controllable heating. Since oxidation is unacceptable in the finished product, Induction is the appropriate choice for heating in an inert atmosphere... 

Annealing brass and bronze tubing prior to bending to form handrails

A twelve-turn helical coil is used to heat an 8 (20.3cm) area 3 (7.6cm) above the end of the tube. Each of the four tubes require a different heat cycle and time to reach the required temperature...

Annealing a zinc wire prior to forming pellets for air rifles

A fourteen-turn coil is used to heat 3.9 (100mm) of zinc wire. The wire is placed in the coil for 5 seconds to reach the desired condition just prior to the forming process...

Annealing the end of a hydraulic motor shaft prior to machining

A three-turn helical coil is used for annealing the motor shaft. The end of the motor shaft is placed in the coil and power is applied for 20 seconds to reach 1350 °F (732 °C) and turn the steel red hot...

Annealing aluminum fuel tank fill neck for bending

An eight turn helical is used to heat the tube for annealing. To anneal the full length of the tube, the tube is placed in the coil and heated...

Annealing of stellite tips on saw blades

A split four turn helical coil is used so the blade can move evenly though the coil. Each tip of the blade is heated for 5 seconds as it passes through the coil to anneal the affected area...

Continuous annealing of copper wire

A twelve turn helical coil is used. A ceramic tube is placed inside the coil to isolate the copper wire from the copper coil and to allow the copper wire to flow smoothly through the coil. Power runs continuously to anneal at a rate of 16.4 yds (15m) per minute....

Annealing lip on cryogenic dewar

A two turn helical coil is used to heat the lip on the cryogenic dewar. The dewar is placed in the coil and power is applied for 2 minutes to anneal the required 1 heat zone...

Anneal an oval cut-out on a stainless steel tube prior to extrusion

A single turn helical coil is used on the 4 (101.6mm) diameter tubes and a two turn helical coil is used on the smaller diameters.

Über Induktionserwärmung

Induktionserwärmung

Induktionserwärmung ist eine schnelle, effiziente, genaue, wiederholbare und kontaktlose Methode, um Metalle oder andere Stromleiter-Materialien zu erwärmen. Das Material kann ein Metall wie Stahl, Kupfer, Aluminium oder Messing sein oder auch ein Halbleiter wie Karbon, Graphit oder Silikon-Karbid. Um nichtleitende Materialien wie Kunststoffe oder Glas zu erwärmen, wird die Induktion verwendet, um einen Stromleiter-Suszeptor wie Graphit zu erwärmen, der dann seinerseits die Wärme auf das nichtleitende Material überträgt.
