High frequency induction heating theory
WebTwo high frequency induction furnaces as schematized in figure 1 are used in our lab. As susceptor as well as carbon source for fullerene or CNT synthesis, highly pure isostatically pressed graphite in the shape of hollow cylinders is used. The graphite susceptor is surrounded by an outer pyrolytic boron nitride (PBN) and an inner carbon shield. WebFrequency. Induction heating systems for hardening are available in a variety of different operating frequencies typically from 1 kHz to 400 kHz. Higher ... High wear and fatigue resistance; Applications. The process is applicable for electrically conductive magnetic materials such as steel.
