1. The intermediate frequency smelting furnace should be used frequently and should not be left for a long time. It should be used for the first time after a long time of storage. It should be blown with a fan for 1 hour to eliminate moisture and clean the dust in the machine. .
2. Always pay attention to the water temperature and water pressure, and all water channels (especially the SCR cooling water channels) must be unblocked, and there must be no water leakage or water blocking.
3. Pay close attention to the indicated value of each instrument of the intermediate frequency melting furnace. The indicated value should be kept stable and there should be no mixing phenomenon. If the instrument is damaged, it should be replaced in time. A fan is installed in the main control box, which has a good cooling effect and eliminates moisture in the main control box. Please always pay attention to the operation of the fan. If it is damaged, it should be replaced in time.
4. Always pay attention to the suction and closing conditions of the main AC contactor and air switch, the temperature and color of the main contact, if the contact is ablated or loosened, deal with it or replace it in time.
5. When running during the yellow mold season and the rainy season, care must be taken to exclude the condensation on the SCR and the main control board.
6. The ground wire connecting the cathode of the oscilloscope to the power supply should be removed to avoid burning electrical components due to the series connection of the grounding point when observing the waveform of the main circuit. Please pay special attention to safety. The housing of the oscilloscope is live.
