How to Repair Induction Melting Furnace Trouble with Various Sounds of Induction Melting Furnace

The sound of the induction melting furnace is also a basic condition for judging the normal operation of the induction melting furnace. The cheerful and harsh whistling sound is also called the whistling of the induction melting furnace. This whistling sound represents the normal operation of the induction melting furnace. The sound that maintenance crews love. So, how to judge the working state of the induction melting furnace from the sound of the induction melting furnace? Let’s introduce them below.

1. Normal whistling sound of induction melting furnace: When the induction melting furnace is working, the frequency of the variable frequency power supply will vibrate naturally, resulting in whistling. This is the sound that the front-line workers of the induction melting furnace like to hear. The induction melting furnace is in good working condition and operates normally.

2. Abnormal noise of induction melting furnace reactor: The reactor in the power supply of the induction melting furnace will make a dull sound due to installation problems or loose coil fixing bolts during use. This induction melting furnace muffled sound is caused by the reactance. When the inverter coil is running, the phenomenon is that the inverter silicon is often burned.

3. The creaking sound of the induction coil of the induction melting furnace: This kind of sound is often the sound of inter-turn firing caused by the short circuit between the turns of the induction coil of the induction melting furnace. The existence of the long-term creaking sound will make the coil copper tube break down, causing It is very dangerous to leak through the furnace, so the insulation between the turns of the induction melting furnace coil must be done well.

4. The crackling sound at the bottom of the induction melting furnace: This sound is generally emitted by the quartz layer at the bottom of the furnace and accompanied by white smoke, indicating that the quality of the quartz sand material, the refractory material at the bottom of the furnace, has problems, the purity is not enough and the moisture content is too large. of.

5. The crackling sound of the induction melting furnace melting scrap metal: This is the sound of metal electromagnetic induction, the discharge sound between metal and metal accompanied by steel flowers, indicating that the melting power of the induction melting furnace is high and the operation is normal.

Through the sound analysis of various induction melting furnaces above, the whistling sound from the resonance of the induction melting furnace is a normal sound, and the low and dull sound is abnormal. Through continuous learning and improvement, we can master the habits of induction melting furnaces and make better use of induction melting furnaces.
