What are the precautions for medium-frequency furnaces?
1. Before turning on the medium-frequency furnace, check whether the electrical equipment, water-cooling system, sensor copper tubes, and other components are in good condition. If not, do not start the furnace.
2. If the medium-frequency furnace overheats beyond the specified limit, repair it promptly. It is strictly prohibited to smelt in crucibles that have already been overloaded during melting.
3. Power transmission must be handled by a dedicated person. After transmission begins, it is strictly prohibited to touch the sensors or cables. Staff members must not leave their posts without permission and should remain vigilant about both the sensors and the surrounding environment.
4. When charging, check whether the furnace contains flammable, explosive, or other hazardous materials—and remove them promptly if necessary. Never directly add cold materials or moisture into the molten steel. Also, avoid introducing large pieces of material if the melt already fills the upper portion, as this could cause the lid to close unexpectedly.
5. When producing furnaces and tungsten, mixing iron or iron oxide is strictly prohibited; silver must be handled with care to ensure tightness.
6. The injection point and the furnace pit should be free of obstructions and standing water, ensuring that any leaked liquid does not fall onto the ground.
7. The central column generator room must be kept clean. Flammable, explosive materials and any other debris are strictly prohibited inside, and smoking is not allowed in the room.
What are the operating conditions for medium-frequency furnaces?
The ambient temperature ranges from 3 to 40°C. The monthly average relative humidity in the area does not exceed 90%. Additionally, there is no conductive dust, explosive gases, or corrosive gases present that could severely damage metals and insulation materials.
What are the installation requirements for medium-frequency furnaces?
First, provide an on-site schematic diagram along with specific site requirements or technical specifications, and then request experts to design a detailed installation layout for the site. Equipment foundation requirements: A flat, cement floor is sufficient—no permanent fixing is needed, though light anchoring may be optional. The equipment should be placed outdoors in a well-ventilated, brightly lit, and shaded area whenever possible. The user is responsible for providing all installation materials, as well as any necessary civil engineering work and essential tools. Additionally, the user will oversee the on-site installation and commissioning process, and conduct hands-on operational training for the staff. If the user has specific requirements, the supplier and customer can reach a mutually agreed-upon arrangement at the time of order placement. Quenching is one of the primary application areas for induction heating.
