How to maintain the intermediate frequency furnace charge

Continuous opening of the furnace is more important to prolong the life of the intermediate frequency furnace charge. If the intermediate frequency furnace cannot be used in succession, then in order to reduce the cracking of the intermediate frequency furnace charge caused by repeated rapid cooling and rapid heating, we can use it after one use. , Add refractory metal charge in the furnace and cover the furnace cover, which can not only preheat the metal charge, but also avoid cracks in the intermediate frequency furnace charge due to rapid cooling.

After the charge of the intermediate frequency furnace is used for a period of time, all the furnace mouths should be removed. The purpose is to check whether the charge is drilled and whether the dry material of the charge is loose and there is a gap. When refinishing the furnace mouth, special attention should be paid to the new and old interfaces. Clean it up and remove it to the bottom of the previous furnace repair interface during the next furnace repair operation, and so on; another point to note is that the furnace mouth and furnace mouth are often slag, corroded and impacted by the charge. Locally, frequent maintenance and repairs are required to ensure the normal maintenance of the intermediate frequency furnace.
