5T induction melting furnace configuration detailed list
The 5T induction melting furnace includes: intermediate frequency power cabinet , capacitor cabinet , aluminum shell furnace , and 531A reducer .
A, IF power cabinet:
1, the phase voltage: 1250V, DC output voltage 1600V, IF voltage: 2300V
DC current: 2200A, power: 3500KW
Intelligent control system
2, KK thyristor 1000A/2500V 24
3, KP thyristor 2500A/3500V 6
4, air switch 4000A
5, installed copper row 120 mm X 6 mm
B, capacitor cabinet:
Capacitor 4000KF/2500V 10 sets
1.85 meters in diameter, 2.1 meters high strength aluminum alloy, 531A reducer 2 sets, water cable 4
Features:
1, the phase voltage is as high as 1250v, and the DC voltage is high, which significantly reduces the loss of electric cabinets, transmission lines and power transformers.
2, the intermediate frequency voltage is up to 2300V, and the booster circuit is adopted. The voltage across the induction furnace is as high as 4600V, which greatly reduces the loss of the induction coil and the water cable.
3,24 1000A/2500V KK thyristors, three sets of KK thyristors in parallel, low power consumption, and the cost of purchasing KK thyristors during maintenance can be reduced by three times (such as damage to four KK2500A/2500V controllable Silicon needs about 3600 yuan, and three sets of KK thyristors are connected in parallel. In the same situation, only one of them will be damaged. The four KK1000A/2500V thyristors only need about 1200 yuan, which greatly reduces the maintenance cost. .
4, increase the furnace body , the new furnace can produce 6.5 tons, the furnace used more late.
5, intelligent system, fast protection, simple structure, easy operation, easy maintenance and repair.
