What are the common faults of induction melting furnace?

가장 일반적인 유형 유도 용해로 is thyristor breakdown, electrothermal capacitor breakdown, and only DC current is used when starting up, and the sound is like a tractor, without the whistling sound of intermediate frequency. The current induction melting furnace control system is simple and the failure rate is relatively low. Pay special attention to water cooling conditions. Generally, if the start fails, the pointer of the DC voltmeter will fall back as soon as it moves. The direct current increases rapidly, and the current rises to the limit instantaneously, which may burn through the silicon controlled element.
