Über Induktionserwärmung

Über 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.
