　　 Energy-saving medium-frequency induction furnace It is a power supply device that converts 50-Hz alternating current into medium-frequency current (ranging from 300 Hz to over 10,000 Hz). It consists of an inverter, a furnace body, and a pre-furnace controller. The heating unit of the energy-saving medium-frequency induction furnace boasts advantages such as compact size, light weight, high efficiency, excellent heat treatment quality, and superior environmental performance. It is rapidly replacing coal-fired furnaces, gas furnaces, oil-fired furnaces, and conventional resistance furnaces. The energy-saving medium-frequency induction furnace represents a new generation of metal heating equipment. Below, we’ll introduce some important operational precautions for its use.

　　1. Before starting the energy-saving medium-frequency induction furnace, please check whether the electrical equipment, water cooling system, and copper tubes of the inductor are in good condition. If not, do not turn on the furnace.

　　2. If the furnace lining wear exceeds the specified limit, it should be repaired promptly. Melting in crucibles that are too deep is strictly prohibited.

　　3. Power transmission and furnace startup should be handled by another person. It is strictly prohibited to touch the sensors or cables after the power has been turned on. On-duty personnel must not leave their posts without authorization and should pay close attention to the external conditions of the sensors and crucibles.

　　4. When charging, please check whether the charge contains flammable, explosive, or other hazardous substances. If it does, remove them promptly. It is strictly prohibited to add cold or wet materials directly into the molten steel in the energy-saving medium-frequency induction furnace. After the molten liquid has been filled into the upper part, it is strictly forbidden to add bulk materials. Prevent covering.

　　5. Repair Energy-saving medium-frequency induction furnace When tamping the crucible, it is strictly forbidden to mix in iron filings or iron oxide. The tamped crucible must be densely packed.

　　6. The pouring area and the pit in front of the furnace shall be free of obstructions and must not accumulate water, to prevent molten iron (or steel) from falling onto the ground and causing an explosion.

　　7. The molten iron (steel) must not be overfilled. When pouring from a ladle, the two components should be properly matched. Walking should be steady, and emergency stops are not permitted. Any residual material left after pouring must be disposed of in the designated area.

　　8. The medium-frequency generator room must be kept clean. It is strictly prohibited to bring flammable, explosive materials or any other debris into the energy-saving medium-frequency induction furnace. Smoking is also forbidden in the room.
