3 T medium frequency induction furnace transformer capacity how to choose?
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 intermediate frequency induction furnace incoming line voltage?
3T frequency induction furnace with the 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 intermediate frequency induction furnace incoming line voltage?
1 , The input voltage of 3T medium frequency induction furnace is 660v , 575v , double rectification 380v ;
2 , do not blindly pursue high voltage (some 3T medium frequency induction furnace 2000KW uses 900V line voltage). Since low current, it has achieved 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 3T medium frequency induction furnace ?
For example: The maximum power of the intermediate frequency power supply of the 3T medium frequency induction furnace is 2000kw , and the intermediate frequency power supply cable of the 2000KW incoming line voltage of 660V = 2000000/660/1.732/2=874mm 2 , and the 10mm × 80mm copper plate should be selected instead of the cable.
How large is the closed cooling tower calculation method for the 3T medium frequency 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 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 3T medium frequency induction furnace using a reservoir?
The 3T 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 50 cubic meters : the cooling effect is poor, and it is easy to block. The investment is minimal and the cooling effect is average.
Determination of energy consumption of 3T medium frequency 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.
