How to choose 3T induction furnace transformer capacity?

        The relationship between the capacity of the intermediate frequency induction furnace transformer and the power of the SCR intermediate frequency power supply is: the value of the transformer capacity = the value of the intermediate frequency power supply , and the transformer of 2000KVA is selected . In order to reduce the interference of harmonics, the special purpose machine is dedicated to one medium frequency induction furnace. Configure a dedicated rectifier transformer.


How to choose the 3T induction furnace incoming line voltage? 
3T induction furnace using an SCR 2000KW frequency power supply 6 is generally a three-phase or six-phase clock pulse wire 12 60V, 50Hz industrial use, arranged pulse rectifier 6-pulse or 12.


Configure 12- pulse double rectification   How to choose the 3T induction furnace incoming line voltage?

1 ,   3T induction furnace incoming line voltage selection is 660v , 575v , double rectification 380v ;

2 , do not blindly pursue high voltage (some   3T induction furnace 2000KW uses 900V line voltage), energy saving has been achieved since low current, high voltage is easy to cause shortened life of electrical components, copper bars, cables are tired, and the life of electric furnace is greatly reduced.


How to calculate the cable of 3T induction furnace ?

For example: The maximum power of the 3T induction furnace's intermediate frequency power supply is 2000kw , and the 2000KW incoming line voltage of 660V is the intermediate frequency power supply cable = 2000000/660/1.732/2=874mm 2 . The 10mm × 80mm copper plate should be selected instead of the cable.


How large is the closed cooling tower calculation method for the 3T induction furnace medium frequency induction furnace ?

Select a mixed water tower to calculate a closed loop cooling tower with a formula of 2000kw × 0.5 × 860 ÷ 5000 = 200T .

Select an integrated layered cooling tower to separately cool the intermediate frequency power supply and the furnace body. The cooling tower tonnage selection formula of the intermediate frequency frequency power supply is: 2000kw × 0.12 × 860 ÷ 5000=40T . The cooling tower tonnage selection formula of the furnace induction coil is: 2000kw × 0.45 × 860 ÷ 5000=160T , the integrated layered closed-loop cooling tower is selected as 40T +1 60T=200T should be selected as a 200T cooling tower, the corresponding model is: ZXZ-200T ( 40/160)


What are the technical requirements for cooling water in each cooling part of 3T induction furnace ?

Different frequency induction furnace cooling portion cooling requirements different from water, an induction coil, a capacitor of the cooling water system using industrial cooling water pressure, the pressure is maintained at 0.15-0.2mpa, water temperature maintained at 20-35 ° C inlet water temperature temperature below 55 ° C.

How large is the 3T induction furnace using a reservoir?

The 3T induction furnace consists of two parts, which are divided into intermediate frequency power supply and furnace body. The same reservoir can be used to cool the outlet water temperature to be controlled within 55 ° C. The reservoir is 50 cubic meters : the cooling effect is poor, it is easy to block, and the general investment The minimum, the cooling effect is general.


Determination of energy consumption of 3T induction furnace

The higher the power of the medium frequency induction furnace, the more power is saved, the energy consumption of the molten iron furnace: 5 2 0KW.h/t temperature 1550 ° C , energy consumption of molten steel furnace 6 0 0 KW.h/t temperature 1550 ° C.

What information does the customer need to provide to the supplier before purchasing the 3T induction furnace ?

1. The medium frequency induction furnace must have room for layout, and it is necessary to provide the area and layout of the plant.

2. The customer needs to provide the capacity of the transformer, the magnitude of the incoming line voltage, and the frequency of the incoming line voltage.

3. The medium frequency induction furnace needs water cooling equipment, and the configuration of the medium frequency induction furnace contains water cooling equipment.

4. The structure of the medium frequency induction furnace has a steel shell body and an aluminum shell body, which requires the customer to specify the furnace structure.

5. The power supply of the medium frequency induction furnace is the intermediate frequency power supply. The line structure of the intermediate frequency power supply is divided into the inverter parallel and the inverter series structure. The inverter series structure is energy-saving, the power factor is 0.98, and the line is stable. The inverter parallel structure is of the common type with a power factor of 0.92, which requires the customer to specify the line structure.
