Causes of nip in the bud of intermediate frequency furnace fault

Our application in medium frequency furnace quenching has been very mature, but the intermediate frequency furnace equipment or some place is prone to failure, in the processwhere the use and operation must pay attention to, so as to avoid accidents.

The first is to wear furnace, liquid steel lining out isfrom, should often detect lining, repairs, or re build furnace, observed on the instrument, usually direct currenthigher than usual, doing little, an unusual sound, can be prevented; followed by the capacitor breakdown, filtering andcompensation capacitor easy breakdown, main due to a bad cooling heating, oil spills, or quality is not good,according to the voltage value using the megger measurementcan detect simple; then is to design a quick may explode,intermediate frequency furnace sound wrong or cannot be established to check; the last is the thyristor maybreakdown, multimeter can be judged, soft breakdown is time-consuming, sometimes not feeding power, each to protect or trip to a certain value, of course, this phenomenon is not necessarily a silicon tube thing, other original bad willcause this phenomenon.

Intermediate frequency furnace and failure to stop the operation, inspection and repair of the, in order to ensure the normal work of the medium frequency furnace.
