Operation method of medium frequency electric furnace
1. Check before starting the mediumfrequency electric furnace : Check the waterway and circuit before starting each time. Make sure that all water pipes are unblocked, and check the circuit for any abnormalities such as loose screws. 2. Turn on the medium frequency electric furnace: turn on the medium frequency electric furnace cabinet power supply, press the control power supply, the control power indicator light is on, close the main circuit switch, and then control the power supply, so that the DC voltmeter should display negative voltage. Then slowly set the power, turn the potentiometer to a large value, and observe the electric meter, the DC voltmeter indicates whether it increases. When the DC voltage crosses zero, the three meters of medium frequency voltage, DC voltage, and active power increase at the same time, and an medium frequency sound is heard, indicating a successful start. The active power can be rotated to the positioner to the required power. Wh...
