    2 ton series induction melting furnace

    Energy 2 tons series induction melting furnace 2 tons series inverter induction melting furnace was developed by our company's energy induction melting furnace type: according to need can choose a single series inverter induction melting furnace , or a two stage (i.e., one for two Induction melting furnace ).

    The 2 ton series inverter inverter induction melting furnace rectifier is divided into single IF power supply ( 6- pulse IF power supply), and double rectifier power supply ( 12- pulse IF power supply) for series inverter operation. It is a series inverter thyristor intermediate frequency power supply technology, and the inverter resonance circuit is series resonance. The rectifier is powered by a 12- pulse SCR intermediate frequency power supply, which does not contain the 5th and 7th harmonic components. According to the harmonic analysis, the harmonic impact of the 12- pulse rectifier power supply is much smaller than that of a 6- pulse ordinary KGPS intermediate frequency power supply. The control system is fully digital, and the start-up success rate reaches 100% . High power factor operating characteristics, power factor is higher than 0.95 . efficient. The load is always full power output, effectively reducing the melting time.

    2. The function, configuration and technical description of the main equipment of the 2- ton series induction melting furnace :

    KYN28-12 type high-voltage cabinet (optional)

    High-voltage cabinet is a hand-mounted switchgear

    The high voltage cabinet is composed of VS1-12 vacuum circuit breaker, lightning arrester, high voltage isolating switch, voltage transformer, current transformer, transformer temperature display, and gas protection.

    Equipped with time-sharing meters, power factor meters, voltmeters, and ammeters on the high voltage cabinet

    2. Rectifier transformer (optional)

    Rectifier transformer is used to reduce the primary high voltage to the input voltage suitable for intermediate frequency power supply. It uses a special high-impedance oil-immersed self-cooled rectifier transformer. S11 type high-performance three-phase oil-immersed distribution transformer 2000KVA

        This rectifier transformer generally adopts the Y / d11 Y0 connection group mode. The secondary output is two sets, one of which is a -type connection, and the other output is a d11 -type connection, so that the phase of the two sets of outputs will The difference of 30 ° from each other forms a 12- pulse rectification method. Compared with the six-pulse rectification, this rectification method can effectively suppress the 5th and 7th harmonics and reduce the interference of harmonic components on the power grid. Therefore, this rectifier transformer is used in large electric furnaces.

    Note: There should be no-load voltage regulating switch on the high voltage side of the transformer. The voltage can be adjusted in five steps: -10 %, -5 %, + 5 %, + 10 %.

    3. ton water-cooling equipment for induction melting furnace in series : (optional)

    HRBL-120T closed circulation cooling tower can also be purchased or built by yourself according to the situation .

    A pool can be built at the production site, and the water can be circulated by a pump to cool a 2- ton series induction melting furnace , or a complete set of combined cooling equipment can be selected. It is recommended to use HRBL-120T closed circulation cooling tower, which can save a lot of production area. The technical parameters of the circulating water cooling ton series induction melting furnace are as follows:
