　　 Intermediate-frequency induction furnace price What are the disadvantages of medium-frequency induction furnaces?

　　The medium-frequency induction furnace is equipped with a comprehensive protection system that includes overcurrent, overvoltage, undervoltage, phase failure, water shortage, and voltage/current limiting features, ensuring the equipment’s reliability and operational stability. It adopts a highly integrated circuit design, making commissioning and operation exceptionally simple and quick. So, what is the price of a medium-frequency induction furnace? What are the drawbacks of a medium-frequency induction furnace?

　　Medium-frequency induction furnace price: What are the drawbacks of medium-frequency induction furnaces?

　　1. High power consumption and high costs.

　　2. The moisture content of the furnace charge must be strictly controlled (no higher than 3%).

　　3. Low desulfurization rate (16%–20%). When processing materials with high sulfur content, necessary desulfurization measures should be taken before smelting.

　　1. The central control circuit board is optimized through computer-aided design and an optimized combination of large-scale integrated circuits. This device features stable performance, reliable quality, and strong anti-interference capability. The components of the medium-frequency induction furnace are arranged reasonably, making maintenance convenient.

　　2. Building on the zero-voltage start-up capability, the medium-frequency induction furnace has been enhanced with automatic frequency sweeping and repeated start-up functions, and its voltage and current loops closely track each other. The device’s start-up and stop operations are both temperature-based, completely independent of current fluctuations. The inverter signal employs a single-signal, high-sensitivity trigger circuit, further improving the device’s start-up performance and ensuring a 100% success rate for start-ups.

　　3. The medium-frequency induction furnace employs a constant-power circuit control system. During the production process, as the charge material changes, the voltage and current can be quickly and automatically adjusted to the set values without manual adjustment or inversion.

　　4. The medium-frequency induction furnace is equipped with a comprehensive protection system that includes overcurrent, overvoltage, undervoltage, phase failure, water shortage, and voltage/current limiting functions, ensuring the equipment’s reliability and operational stability. It adopts a highly integrated circuit design, making commissioning and operation exceptionally simple and quick.

　　Emergency Handling of Cooling Water

　　1. The dual-power switch in the distribution cabinet of the electric furnace control room should be kept in the auto-transfer position. When the main power supply is cut off, the emergency power supply will automatically engage and immediately restart the furnace water pump.

　　2. When both the main power supply and the emergency power supply simultaneously go out, you must take action immediately. Notify the on-duty electrician to prepare to start the emergency generator and ensure that, once the furnace small water pump has power, it can operate the furnace cooling water system. Therefore, the diesel generator must always have a sufficient supply of diesel fuel, and it should be run once every month along with the equipment.

　　3. When the diesel generator fails to start, Ma will connect tap water to the furnace body.

　　4. Due to the power outage, the water supply to the induction coil was cut off, and the heat conducted from the molten iron was extremely intense. If the coil remains without water for an extended period, the water inside the induction coil could turn into steam, disrupting the coil’s cooling system. As a result, the rubber hoses connected to the induction coil and the insulation of the coil itself could be burned out.

　　Emergency Handling of Molten Iron in the Furnace

　　1. A power failure will occur once the cold charge begins to melt. If the charge hasn't fully melted, there's no need to tilt the furnace. Just leave it as it is and keep circulating water; wait until the next power-on cycle to resume melting.

　　2. Due to a fault in the intermediate-frequency power supply, the molten iron has already been melted, but the amount of iron is relatively small and insufficient for pouring (e.g., the temperature hasn't reached the required level or the composition doesn't meet specifications). In this case, you could consider tilting the furnace to a certain angle and allowing the iron to solidify naturally. If the quantity is large, you might want to consider pouring the molten iron out instead.

　　3. Due to a sudden power outage, the molten iron has already melted. Try to insert the pipe before the molten iron solidifies, so that gases can be vented when the molten iron melts again, preventing gas expansion from causing an explosion.

　　4. When the solidified charge is melted for the second time by reapplying power, the furnace body should be tilted forward at a certain angle so that the molten iron at the bottom flows out from the lower, inclined section, thereby preventing an explosion.
