After the intermediate frequency furnace has been used for a long time, spare parts need to be replaced in case of failure and damage. The intermediate frequency power supply cabinet mainly includes electronic components such as main control board, pulse board, thyristor, etc. The intermediate frequency furnace part mainly includes induction coils, water-cooled cables, etc. The long-term operation of the intermediate frequency furnace also requires sufficient consumables, such as crucibles, furnace lining materials, glass cloth (mica paper), water glass, etc.
