中频炉有哪些常见故障?

中频炉最常见的就是可控硅击穿，电热电容击穿，开机只有直流电流，声音像拖拉机一样，没有中频的啸叫声。现在的中频炉控制系统简单，故障率比较低的。特别要注意水冷条件。一般启动失败的话都是直流电压表指针刚一动作就会回落。直流电流迅速增大，电流瞬间上升到极限，很可能会烧穿可控硅元件。

What are the common faults of induction melting furnace?

The most common type of induction melting furnace 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.
