Shutdown operation of the metal melting furnace

1. When stopping, first turn the power adjustment button to a smaller position, and then press the “inverter stop” button.

2. If you need to stop for a long time, press the “Inverter stop” first, then press the main current disconnect button, and finally press the “Control power disconnect” button. (The above steps cannot be inverted!) At this time, you can turn off the internal circulating cooling water of the intermediate frequency power supply and the electric heating capacitor (referring to stop the operation of the circulating water pump of the system), and the internal and external circulation system of the furnace body should wait until the surface temperature of the furnace lining is reduced to 100°C The following time (generally 72 hours should be passed), the pump can be stopped and the water operation can be stopped.

3. If cooling water is stopped in winter, it must be considered that the water in the pipeline will freeze and crack the water pipe (the method of heat preservation, draining water, adding water glycol, etc. can be used).
