Detailed configuration list of KGPS-5T induction melting furnace

1. Electric cabinet:

1. Phase voltage: 1250V, DC output voltage 1600V, intermediate frequency voltage: 2300V

　 DC current: 2200A, power: 3500KW

　 Intelligent control system

2. KK Thyristor 1000A/2500V 24 pcs

3. KP SCR 2500A/3500V 6 pcs

4. Air switch 4000A

5. Installed copper bar 120 mm X 6 mm

2. Capacitor cabinet:

　 Capacitor 4000KF/2500V 10 units

Three, induction furnace

　 1.85 meters in diameter, 2.1 meters in height, double-layer furnace body, inner layer of high-strength aluminum alloy, outer layer of high-quality stainless steel

　 2 531A reducers, 4 water cables

　 Total machine: 360,000 yuan (single furnace); 510,000 yuan (double furnace)

Features:

1. The phase-in voltage is as high as 1250v, and the DC voltage is high, which significantly reduces the loss of electrical cabinets, transmission lines and power transformers.

2. The intermediate frequency voltage is as high as 2300V, and the booster circuit is adopted, and the voltage at both ends of 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 groups 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 4 KK2500A/2500V controllable (Silicon costs about 3,600 yuan, and three sets of KK SCRs are connected in parallel. Under the same circumstances, only one of them will be damaged. 4 KK1000A/2500V SCRs only cost about 1,200 yuan, which greatly reduces the maintenance cost) .

4. Increase the induction furnace, the new furnace can produce 6.5 tons, and the furnace will be used later to produce more.

5. Intelligent system, fast protection speed, simple structure, convenient operation and easy maintenance.
