Medium frequency Steel-shell furnace It has a wide range of applications and is used frequently, so proper maintenance is essential. Let’s take a look at the key points below:

1. Regularly remove accumulated dust from inside the power cabinet, paying special attention to cleaning the exterior of the thyristor chips thoroughly with alcohol. Frequency converters in operation generally have dedicated control rooms; however, the actual working environment is often less than ideal. In the melting and forging processes, there is significant dust and intense vibration. In the induction heating and quenching processes, the equipment room is located near operations such as acid pickling and phosphating, where corrosive gases are abundant. All these factors can adversely affect medium-frequency inverters. Steel-shell furnace The components of equipment-related devices can cause damage. When dust accumulates heavily, the insulation strength of the device may be reduced, often leading to surface discharge phenomena on component surfaces. Therefore, it is essential to pay close attention to regular cleaning to prevent malfunctions.

2. Regularly inspect the bolts on all components of the equipment as well as the contacts of contactors and relays. If any looseness or poor contact is detected, promptly repair or replace the affected parts—do not continue to use them under such conditions. To prevent serious accidents, regularly replace or clean the critical components of energy-saving medium-frequency steel-shell furnaces.

3. Use tap water or well water as an energy-saving medium-frequency power supply. Steel-shell furnace When using cooling water sources, scale tends to accumulate, which can impair the cooling efficiency. If plastic water pipes become aged and develop cracks, the equipment should be replaced promptly. During summer operation, using tap water from wells for cooling often leads to condensation. Therefore, it is advisable to consider adopting a recirculating water system; if condensation becomes severe, the system should be immediately shut down.

4. The scale accumulated inside the heating induction coil of the Luoyang medium-frequency furnace should be cleaned promptly; any cracks in the thermal insulation lining must be replaced without delay. After replacing the lining of the melting furnace, careful inspection is essential. The loads connected to the variable-frequency insulation devices are all located at the work site, where failures tend to occur more frequently yet often go unnoticed. Therefore, strengthening maintenance of the loads on energy-saving Luoyang medium-frequency furnaces and preventing faults from affecting the variable-frequency power supply are crucial steps to ensure the proper operation of the entire system.
