　　With the development and promotion of induction furnaces for casting, the demand in the field of metal hot working is steadily increasing. Casting electric furnace During operation, it utilizes the principle of electromagnetic induction, making it more energy-efficient and environmentally friendly compared to traditional coal-fired furnaces. In the later stages of using the induction casting furnace, it is essential to perform basic maintenance and management tasks to prevent issues such as failure to start up normally, unusual noises, and thyristor burnout.

　　(1) Inspect and clean the radiator to maintain efficient cooling performance; if necessary, perform acid cleaning.

　　(2) Check whether the water-cooling system has any blockages or leaks, and verify that the water-pressure relay is sensitive. The temperature difference between the inlet and outlet water should generally not exceed 35℃.

　　(3) Check the insulation of the induction coil for any signs of water leakage.

　　(4) Check whether the wires and switches are damaged.

　　(5) Inspect the cleaning water tank, check the drain valve, and remove some wastewater to prevent scaling.

　　(6) Clean oil stains and dust from various electrical components and other equipment; use a fan or air blower to remove dust.

　　(7) Check whether the wiring screws are tightened to ensure good contact.

　　(8) Check whether the thyristors, circuit busbars, transformers, and various cable segments are overheating.

　　The widespread application of medium-frequency induction furnaces in real life is closely linked to their effective maintenance practices.

　　First, it’s essential to perform thorough pre-startup inspections, especially of the furnace lining. Check whether the lining is intact and look for cracks, furnace openings, corrosion, and other defects to ensure a smooth startup.

　　Second, before adding the pig iron, the amount of scrap steel should be determined based on the impact of the pig iron on the furnace bottom. Carbon additives and scrap steel can be added, and after the iron has melted, it can be returned to the furnace.

　　When discharging the material, avoid impacting the liner and reduce the power to prevent the material from being lifted up and covered.

　　We recommend that you use the induction furnace appropriately and strictly follow the operating guidelines when handling it. Avoid... Casting electric furnace Causing unnecessary damage. The maintenance methods for electrical equipment are closely related to the type of equipment, its technical requirements, operating conditions, and available tools. Generally, there are six common methods used in the daily maintenance of electrical equipment. 1. **Visual Inspection**: Observe any changes in the appearance of electrical equipment components. For example, check whether fuses have blown, fasteners are loose, or insulators have become carbonized and turned black. Also, observe the readings displayed on monitoring instruments or the status indicated by signaling devices. 2. **Auditory Inspection**: Listen carefully to any changes in the sounds produced by electrical equipment during operation to assess its working condition. For instance, an asynchronous motor that cannot start on its own will typically emit a “buzzing” sound; when a motor bearing is damaged, it may produce a “rustling” noise. 3. **Olfactory Inspection**: Smell any odors emitted by electrical equipment during operation. For example, if the temperature of electrical equipment rises above the limit due to faults such as short circuits or overloads, you might detect a pungent burning smell. 4. **Tactile Inspection**: Roughly determine whether the operating conditions of low-insulation or general equipment are normal by touching the surface of the equipment’s enclosure to feel its temperature. 5. **Testing**: Use commonly available measuring instruments to test various operational parameters and insulation resistance values of the electrical equipment. 6. **Performing Maintenance Tasks**: Carry out regular cleaning, inspection, and maintenance according to the scheduled maintenance plan for electrical equipment.
