Second, the structure analysis of medium frequency copper melting furnace

The intermediate frequency copper melting furnace is composed of a furnace body, a tilting furnace controller, a thyristor intermediate frequency power supply device and a cooling water distributor.

1. The medium frequency copper melting furnace body consists of the furnace shell, induction coil and furnace lining (the furnace lining is prepared by the user according to the formula provided by this manual), and the RZS type gearbox is mainly composed. Induction coil water-cooled cable, capacitor cabinet, thyristor intermediate frequency power supply cabinet must be cooled by water, the furnace lining is close to the induction coil, and it is made of quartz sand. The tilting of the furnace body is directly driven by the tilting gearbox. The deceleration is a two-stage worm gear shifting, which has good self-locking property and is stable and reliable when rotating. In case of emergency power failure, the furnace can be manually tilted to avoid danger.

2. Medium frequency copper melting furnace tilting controller

   The tilting furnace controller can select the control of the electric motor on the tilting gearbox of the two furnaces by selecting the furnace switch, and the tilting furnace controller can be appropriately moved according to the needs of the operator, and the tilting and resetting of the furnace body is performed. Jog control.

3. Medium frequency power supply unit

  The thyristor intermediate frequency power supply is a device that converts the three-phase power frequency into a single-phase intermediate frequency to supply the power required by the furnace. The circuit principle and use and maintenance are detailed in the instruction manual.

4, medium frequency copper melting furnace water distributor

The induction heating cooling water distributor is a device for supplying cooling water for the induction coil, water-cooled cable and capacitor cabinet of the furnace. (The sensor of the unused melting furnace and the cooling water of the water-cooled cable can be closed by the valve, and the water supply of the intermediate frequency device is directly connected by the water pipe. Does not pass moisture configuration).
