感應熔煉爐故障排除技巧

1.之後 感應熔煉爐 fails, the situation of the failure type should be fully understood.

（1）詳細詢問感應熔煉爐操作人員；

(2) By looking, listening, smelling, touching, etc., find out whether the components in the power supply system of the induction melting furnace have special phenomena such as cracking, noise, odor, overheating, etc.;

(3) The induction melting furnace can be powered on for commissioning only when it is determined that the induction melting furnace is not dangerous. Through the above understanding of the induction melting furnace, the fault of the induction melting furnace can be accurately determined. This is the basis for analyzing the failure of the induction melting furnace. If the failure phenomenon is not clear, it will cause a deviation in the failure analysis.

2、對感應熔煉爐的故障進行分析，確定感應熔煉爐的故障範圍。 根據感應熔煉爐的故障現象，結合感應熔煉爐的原理和控制特點，分析確定感應熔煉爐的故障範圍。 是電氣故障還是機械故障？ 是直流電路還是交流電路？ 是主電路還是控制電路？ 還是輔助電路？ 是電源部分還是負載部分？ 還是控制線部分？ 還是參數調整不當造成的？ 還有可能嗎？

3、通過對感應熔煉爐的檢測、分析和判斷，縮小感應熔煉爐的故障範圍。 故障排除的過程往往是分析、檢測和判斷的過程，逐步縮小感應熔煉爐的故障範圍。

綜上所述，靈活運用上述“中頻爐故障維修技巧”，逐步縮小中頻爐故障範圍，直至發現並解決中頻爐故障點。
