The sound of the medium frequency electric furnace judges the working status of the machine
The sound of the medium frequency furnace is a basic condition for judging whether the medium frequency electric furnace is working properly. The cheerful and harsh whistling sound is also called the whistling of the medium frequency furnace. This whistling sound represents the normal operation of the medium frequency furnace, and is also a favorite of the medium frequency furnace debuggers and maintenance personnel. sound. So, how to judge the working status of the medium frequency furnace from the sound of the medium frequency furnace?
- The normal whistling sound of the medium frequency furnace: When the medium frequency furnace is working, the frequency of the frequency conversion power supply will naturally cause vibration and produce a whistling. This is the sound that the frontline personnel of medium frequency furnace production like to hear. This sound indicates that the medium frequency furnace is working. In good condition, everything is running normally.
- Abnormal medium frequency furnace reactor noise: The reactor in the medium frequency furnace power supply will make a dull sound due to installation problems or loose coil fixing bolts during use. This muffled sound of medium frequency furnace is operated by the reactor coil. The phenomenon is that inverter silicon is often burned.
- Puff sound of induction coil of medium frequency furnace: Induction coil of medium frequency furnace is short-circuited, and the inter-turn ignition will make this sound. The existence of long-term puff sound will cause the copper tube of the coil to be broken down, causing water leakage and causing the furnace. It is very dangerous to wear the furnace, so the inter-turn insulation of the medium frequency furnace must be done well.
- The crackling sound at the bottom of the medium frequency furnace: this sound is usually emitted by the quartz layer at the bottom of the furnace and accompanied by white smoke, indicating that the quality of the refractory quartz sand at the bottom of the furnace is defective, and the purity is not enough and the moisture content is too large. .
- The crackling sound of the medium frequency furnace melting scrap metal: This positive sound is the sound of electric discharge between the metal and the metal in the metal electromagnetic induction, accompanied by steel flowers, indicating that the medium frequency furnace has a large melting power and is operating normally.
Through the above sound analysis of various medium frequency furnaces, the whistling sound of the resonance of the medium frequency furnace is normal, and the low and dull sound is abnormal. Through continuous learning and continuous improvement, can we master the habit of the medium frequency furnace and use the medium frequency furnace better.
