KGPS-3T-3 type induction melting furnace detailed configuration list
KGPS-3T-3 induction melting furnace, compared with other types of 3T electric furnaces, can save 80-100 degrees of electricity per ton of steel (melting power consumption can be as low as 500 degrees per ton of molten steel).
1. Electric cabinet:
1. Rated phase-in voltage: 1250V, intermediate frequency output voltage 1900V, DC current: (maximum) 2000A, power (maximum): 2000KW
2. KK Thyristor 1000A/2500V 24 pcs
3. KP SCR 2000A/3500V 6 pcs
4. Air switch 3500A
5. Installed copper bar 100mm X 6mm
6. Reactor (copper tube 20mmX20mm, wall thickness 2mm coil, 12 pieces), a balanced reactor
6. Intelligent system
2. Capacitor cabinet:
Capacitor 2000KF /1900V 18 sets
Reducer: 531 (double)
Furnace shell: diameter 1500 mm high 1700 mm.
Induction coil copper tube 30 mm X 60 mm X 4 mm inner diameter 950 mm 19 coils.
1. Intelligent system, fast protection speed, durable thyristor, good starting performance, stable work and convenient operation.
2. Using large copper busbars to save electricity.
3. Special cooling ring for furnace bottom, durable for furnace bottom, not easy to wear, low furnace bottom loss; using booster circuit, the voltage at both ends of the electric furnace can reach 3200V (2 times the output voltage of the electric cabinet), water cable, induction coil loss Small; 1000V phase-in voltage, reactor, equipment
The machine copper bar and the incoming phase cable loss are small; 24 1000A/2500V KK SCRs, three sets of KK SCRs are connected in parallel, low power consumption, and the cost of purchasing KK SCRs during maintenance can be reduced by three times (if damaged Four KK2500A/2500V thyristors cost about 3600 yuan, and three sets of KK thyristors in parallel will only damage one of them under the same circumstances, and four KK1000A/2500V thyristors only cost about 1200 yuan , Greatly reducing maintenance costs)
