Maintenance methods after the intermediate frequency furnace is shut down
In actual production, affected by the production cycle, the furnace does not shut down. It is basically a state of stopping, starting, starting, and stopping, so be prepared to shut down the furnace. Maintenance is very important. When the intermediate frequency furnace is cooled rapidly, it is easy to cause the furnace wall to crack, so the intermediate frequency furnace should be cooled slowly. During the cooling process of the intermediate frequency furnace, the molten iron in the furnace is in a close state with the lining in the furnace. Due to the effect of thermal expansion and contraction, the lining plate is cracked. If it is not repaired in time, a second damage will occur when the machine is turned on for heating next time. causing the fault to expand.
Unused molten iron in the furnace should be stored outside to avoid cooling in the furnace. At the same time, the cooling water supply volume of the intermediate frequency furnace is reduced, the cooling speed is delayed, and the occurrence of cracks is avoided. Therefore, the key points of stopping the intermediate frequency furnace are: avoid rapid cooling and rapid heating, remove the molten iron in the furnace before cooling, and avoid cooling of the molten iron.
