　　1. Maintenance Medium-frequency furnace To ensure that all product performance of the machinery is checked during a weekly or biweekly shutdown, enabling us to promptly understand the equipment’s condition, the following are the specific details for the medium-frequency furnace maintenance.

　　2. To ensure the medium-frequency furnace is used more effectively during operation, you should:

　　(1) Use a temperature-measuring gun to monitor the thymus temperature, resistance temperature, and operating temperature of the resistor. The temperature-measuring process is divided into three stages; naturally, the above-mentioned three temperature readings must be recorded to promptly detect and address any issues that may arise.

　　(2) Check daily whether the cable screws are loose.

　　(3) Before starting the medium-frequency furnace, make sure to turn on the power pump and the furnace water pump every day. The water pressure in the power supply box should be 1.5–1.7 kg, while the water pressure in the furnace should be 1.5–2 kg.

　　(4) Keep the furnace water cables and their surrounding areas clean, free of iron filings and metallic objects.

　　3. Before starting the equipment, we need to start the pump 10 minutes in advance to check for any leaks. If we detect a leak, we should address it immediately to avoid serious disruptions to production.

　　4. If Medium-frequency furnace Anomalies have been detected in the temperature data of the thyristor. The primary cause should be promptly investigated—whether the water pipe is kinked, leading to insufficient water flow and inadequate heating, or whether there’s a blockage caused by dirt buildup inside the thyristor’s sleeve.

　　5. If we find that the operating temperature of a resistor-capacitor combination differs significantly from that of other resistors, and there’s no evidence of capacitor failure or resistor damage, we should immediately perform a thorough inspection. This will become particularly evident when the reactor emits a noticeable buzzing sound and feels slightly shaky upon being powered on.

　　6. Inspect and maintain weekly or biweekly. Medium-frequency furnace At the time, note:

　　(1) Check whether the wire channels above the inverter’s resistor and capacitor protection have any loose components, to prevent short circuits caused by unshielded resistors and damage to the KK tube. If you find anything loose, secure it with a rope.

　　(2) Tighten the screws and water clamps of the system equipment once a week to prevent damage and equipment failure caused by drops or loosening.

　　(3) Observe the hydraulic oil once a week to check whether it is unscientific. Generally, at least 80% of the oil should be present.

　　(4) Regarding the site conditions, some manufacturers have poor water quality—please take appropriate measures. Medium-frequency furnace Is there nozzle corrosion in the channel power channel?

　　7. Clean the tubing assembly with 20% dilute hydrochloric acid in a circulating loop for 10–15 minutes. After general cleaning, flush once with 100% water and then dry thoroughly using compressed air to prevent the sleeves from being corroded by the hydrochloric acid.

　　8. Key points for hydraulic maintenance: When using hydraulic oil, pay attention to both cleanliness and oil level. Generally, hydraulic oil should be replaced every six months, and the filter screen should be cleaned monthly. Please note that there are two filters in the hydraulic station. Do not allow them to operate at the bottom of the hydraulic station. Be sure to place them on a shelf inside the hydraulic station to prevent iron filings from the medium-frequency furnace hydraulic station from entering the hydraulic pump and damaging it.
