KGPS-1.5T-3 type intermediate frequency furnace detailed configuration list
KGPS-1.5T-3 type induction melting furnace, compared with other types of 1T electric furnaces, can save 80-100 degrees per ton of steel melting
(The power consumption for smelting can be as low as 520 degrees per ton of molten steel).
1. Electric cabinet:
1. Rated phase-in voltage: 700V, intermediate frequency output voltage 1300V, DC current: (maximum) 2000A, power (maximum): 1500KW
2. KK Thyristor 1000A/2000V 16 pcs
3. KP SCR 2000A/2500V 6 pcs
4. Air switch 2500A
5. Installed copper bar 80mm X 6mm
6. Reactor (copper pipe 16mmX15mm, wall thickness 1.5mm coil, 12 pieces), a balanced reactor
6. Intelligent system
2. Capacitor cabinet:
Capacitor 2000KF /1200V 9 sets
Three, stove
Reducer: 531A
Furnace shell: diameter 1330 mm high 1390 mm.
Induction coil (weight: 290 kg): Copper tube 25 mm X 40 mm X 3 mm, inner diameter 760 mm 20 circles.
Features:
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 the bottom of the furnace, the bottom is durable, not easy to wear, and the bottom loss of the furnace is small; using a booster circuit, the voltage at both ends of the electric furnace can reach 2600V (2 times the output voltage of the electric cabinet), water cable, induction coil loss Small; 700V phase-in voltage, reactor, equipment
The machine copper bar and the incoming phase cable loss are small; 16 1000A/2500V KK SCRs, two sets of KK SCRs are connected in parallel, low power consumption, and the cost of purchasing KK SCRs during maintenance can be reduced by two times (if damaged Four KK2000A/2500V thyristors cost about 2900 yuan, and two sets of KK thyristors in parallel will only damage one of them under the same circumstances, and two KK1000A/2500V thyristors only cost about 1200 yuan. , Greatly reducing maintenance costs).
