　　The whole set Casting electric furnace The production equipment mainly includes a medium-frequency power supply cabinet, compensation and capacitors, two furnace bodies, water-cooled cables, and a gearbox. Each furnace body consists of four components: the furnace shell, the induction coil, the furnace lining, and an inclined reduction furnace. The furnace shell is made of non-magnetic material, while the induction coil is a rectangular hollow tubular helix through which cooling water flows during melting. The coil is connected via copper busbars to the cables of the water-cooling system. The furnace lining, which closely surrounds the induction coil, is developed by compacting and sintering quartz sand. The tilting of the furnace body is directly driven by the tilting gearbox. The discharging gearbox is a two-stage turbine-type speed-reducing device with excellent self-locking performance, ensuring smooth and reliable rotation. At the end of the gearbox, there is an emergency power-off mechanism for discharging, which helps prevent potential hazards. Simultaneously, the tilting gearbox motors of two furnace bodies can be analyzed and selected via a furnace-selection switch. The switch box, equipped with a four-core rubber cable, allows operators to stand in their most convenient working position and control the tilting and resetting of the furnace bodies electrically.

　　Casting Electric Furnace Operating Procedure

　　1. Operators must understand the following points:

　　A. Casting electric furnace The structure and performance of the equipment and its auxiliary devices.

　　B. Layout of the power distribution system, layout of the control system, layout of safety facilities, etc.

　　C. Operating Procedures and Safe Operation Guidelines.

　　2. Check the preparatory work before operating the casting furnace.

　　A. Can the equipment be powered normally by the utility company? Are there any phenomena such as phase failure, open circuits, or exposed wires?

　　B. Check whether the grounding device connections are secure.

　　C. Check whether the heating element is damaged, whether the connections at each joint are in good contact, and whether there is any contact with the furnace body or the cover shell.

　　D. Check whether the temperature control system is functioning normally.

　　E. Check whether the furnace door lift and carriage are functioning abnormally.

　　3. It is strictly prohibited to introduce workpieces containing corrosive, volatile, or explosive gases into the furnace for analysis and processing, as this could impair performance, shorten the service life of heating elements and refractory materials, and even lead to accidents such as information explosions.

　　4. Casting electric furnace Do not operate under ultra-high temperatures; otherwise, the equipment's service life will be shortened.

　　5. The workpieces should be stacked evenly, with a distance of approximately 100–150 mm from the heat-generating reaction components.

　　6. Before loading the workpiece into the furnace, remove any excessive scale using a wire brush.

　　7. It is strictly prohibited to handle workpieces carelessly to avoid impacts.

　　8. Operators must not leave their posts without permission when using the casting electric furnace, and must constantly monitor whether the furnace is operating normally.

　　9. When装卸 the working components of a casting electric furnace, first disconnect the power supply to the heating elements to ensure the safety of personnel during operation.

　　10. The oxidation furnace (including the electric heating element) should be cleaned regularly—at least once a week or after every five uses. Compressed air can be used to blow underneath the furnace’s bottom plate.

　　11. After use, the resistance wire must not be subjected to impacts or bends, as this could cause it to break.

　　12. Regularly inspect the electrical circuits and motors of the casting furnace, add lubricating oil, and pay attention to safety.

　　13. Regularly inspect the condition of the heating elements. After short-term use, the heating elements must not be bent or subjected to impacts. If there is no severe corrosion or damage, electrodes can be made from the same material as the heating element itself (or from the heating element wire itself) and welded using acetylene gas. The electrodes should contain a 50% mixture of dolomite powder. If the heating elements are severely corroded and thus unusable, they should be replaced.

　　14. Regularly check the deviation of casting electric furnace analytical instruments and thermocouples to prevent inaccurate temperature measurements caused by instrument and thermocouple errors, which could affect the quality of the company’s products and services.
