New IGBT intermediate frequency bar heating furnace
Technical characteristics of the new IGBT intermediate frequency bar heating furnace:
1. Global procurement of IGBT devices and components
2. Adopt high-efficiency combined resonance technology
3. Use low inductance circuit arrangement
4. Using large-scale digital circuits
5. Adopt comprehensive and mature protection technology
Three advantages of the new IGBT intermediate frequency bar heating furnace:
1. Significantly save electricity, each ton of steel heated consumes 320 degrees of electricity. Compared with thyristor intermediate frequency, it can save power by 20%-30%.
2. It will not cause grid-side pollution, the power supply transformer does not generate heat, the substation compensation capacitor does not generate heat, and does not interfere with the operation of other equipment.
3. Reduce the capacity of the power supply transformer.
Energy saving effect of new IGBT intermediate frequency bar heating furnace
300kw IGBT intermediate frequency bar heating furnace: 10 tons of forgings can be produced in shifts, 80-100 kWh per ton, 800-1000 kWh per shift, 560-700 yuan per shift, and more than 20,000 yuan per month; double shifts Or three-shift production, saving more than 40,000-60,000 yuan in electricity bills per month. The equipment investment can be recovered within a few months.
