2 tons one to two induction melting furnace : is my company developed energy-efficient induction melting furnace type is the future mainstream fashion one with two induction melting furnaces . Each set of two- ton, one-to-two induction melting furnaces consists of a 12- pulse rectifier power transformer, a 12- pulse intermediate frequency power supply, and two two- ton electric furnace furnaces. A set of intermediate frequency power supplies power to the two electric furnaces. Inverter series resonance design of 2 tons one to two induction melting furnace , full open rectification angle 0 , high power factor, small high harmonics. Digital electronic control, open-type induction melting furnace structure design, easy equipment maintenance, in line with international and domestic standards for electrical safety design standards.

One to two induction melting furnace working mode :

Smelting of two furnaces at the same time

One set of furnace body for smelting production, the other set of furnace body insulation

One set of furnace body is smelted and the other set is used

First, one for two induction melting furnace main equipment function, configuration and technical description:

. 1 , 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-cooling rectifier transformer. S11 type high-performance three-phase oil-immersed distribution transformer 1500KVA

    This rectifier transformer generally adopts the Y / d11 , Y0 connection group mode. The secondary output is two sets, one of which is a Y -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.

Parameters of 12- pulse rectifier power transformer:

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 %, 0 , + 5 %, + 10 %.

3 , 2 tons one to two induction melting furnace main technical parameter configuration 

Features: 2 tons one to two induction melting furnace has significant energy saving effect

1. The rectifier is powered by a 12- pulse SCR intermediate frequency power supply, which does not include 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% . 

2. The series inverter uses a half-bridge circuit, the number of main circuit components is relatively reduced, and it has a high power factor, so it has higher power. 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. Note: The average power factor of the inverter electric furnace with parallel inverter technology is 0.85 . 

3. Compared with other circuits, the load circuit current is 10-12 times smaller, which can save operating power consumption by 3%.  

4. No large-capacity filter reactor is needed, which can save power consumption by 1% 

5 , each induction furnace powered by a separate set of the inverter without having to install large-current switching converter furnace can save power consumption of 1%  

6. The series inverter has no power concave corners, that is, the power loss , in the operating power characteristic curve, which significantly reduces the melting time, which not only increases production and saves power consumption, but also saves energy by 7%.     

Two, two ton, one to two induction melting furnace water cooling equipment:

(Optional) According to your own situation, you can also buy it yourself or build your own cooling pool to eliminate the HRBL-100T closed circulation cooling tower.

Pool in the production site can be built, for circulating water through the pump 2 tons, one dragging two induction melting furnace cooling, it can also be used in combination package type cooling apparatus. It is recommended to use HRBL-100T closed circulation cooling tower, which can save a lot of production area. The technical parameters of the 2 ton, one tow, two induction melting furnace with circulating water cooling are as follows:
