How to choose the 1T medium frequency induction furnace transformer capacity?

  In order to reduce the interference of harmonics , the transformer of 1000KVA is selected as far as possible for special plane. One medium frequency induction furnace is equipped with a dedicated rectifier transformer.

How to choose the 1T intermediate frequency induction furnace incoming line voltage? 
1T frequency induction furnace using 800kw-1000KW generally an SCR frequency power supply 6 with 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 1T intermediate frequency induction furnace incoming line voltage?

1 ,   The input voltage of 1T medium frequency induction furnace is 660v , 575v , double rectification 380v ;

2 , do not blindly pursue high voltage (some   1T medium frequency induction furnace 1000KW uses 900V line voltage). Since low current, it achieves the purpose of energy saving. High voltage is easy to shorten the life of electrical components, copper bars and cables are tired, which makes the life of electric furnace greatly reduced.

How to calculate the cable of 1T medium frequency induction furnace ?

For example: The maximum power of the intermediate frequency power supply of 1T medium frequency induction furnace is 1000kw , the intermediate frequency power supply cable of 1000KW is 1000000/660/1.732/2=437mm 2 , and the 6mm × 80mm copper plate should be selected instead of the cable.

How large is the closed cooling tower calculation method for 1T medium frequency induction furnace ?

Select a mixed water tower to calculate a closed loop cooling tower with a formula of 1000kw × 0.5 × 860 ÷ 5000 = 86T .

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: 1000kw × 0.12 × 860 ÷ 5000=20T , and the cooling tower tonnage selection formula of the furnace induction coil is: 000kw × 0.45 × 860 ÷ 5000=60T , the integrated layered closed-loop cooling tower is selected as 20T + 60T=80T should be selected as 80T cooling tower, the corresponding model is: ZXZ-80T ( 20/60)

Determination of energy consumption of 1T medium frequency induction furnace

The higher the intermediate frequency power supply of the medium frequency induction furnace, the more power is saved, the energy consumption of the molten iron furnace: 60 0KW.h/t temperature 1550 ° C , energy consumption of molten steel furnace 650 KW.h/t temperature 1550 ° C.

What information does the customer need to provide to the supplier before purchasing the 1T IF 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.

What are the technical requirements for cooling water in the cooling parts of 1T medium frequency 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 1T medium frequency induction furnace using a reservoir?

The 1T medium frequency 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 30 cubic meters : the cooling effect is poor, and it is easy to block. The investment is minimal and the cooling effect is average.
