What are the performance and differences between intermediate frequency furnace and industrial frequency furnace?

The most frequent use of relau frekuensi pertengahan is heat treatment, the frequency is 800～10000Hz. Fast speed, high efficiency and low pollution. One type of power frequency electric furnace is resistance heating furnace, and the other is induction heating. Structurally, the intermediate frequency electric furnace is generally a coreless induction coil, and the industrial frequency electric furnace is an induction coil with a magnetic core.
