IGBT Induction Heating Machine

Share:

Power: 100--1000KW

Work Frequency: 0.5-10Khz

Application: For billet partial and total hot forging

Turnkey induction heating system, including the induction power supply, heating furnace, water cooling system, automatic steel bar feeding, infrared sensor, bar sorting system, easy to put into hot forging production line.


Technical information

1. Good start up performance: IGBT MF induction power supply apply series resonance technology so it can be starts up 100% under any condition.

2. Less indterface to power grid: Less harmonic current and high power factor, Power factoer remaining 0.95 above during machine running.

3. Low energy consumption: in series resonant circuit,voltage at inductor high and current low so energy loss is very low; Soft switch technology applied then switch loss is very low.

4. Water cooled by heat exchanger: Using distilled water as circulating water to avoid sediment and clog of hose.

5. Good reliability: IGBT is a self turn-off transistor that ensures incersion with suvvess and takes protection instantly; IGBT used form Infineon world-renowned manufacturer.

6. High conversion efficiency more than 97.5%: IGBT(Insulated Gate Bipolar Transistor)inversion technology.

7. Energy saving up to 15%-30% compared with SCR technology induction machine: LC series resonance circuit and voltage feedback design, low energy comsumption.

8. Cooper &stainless steel fasteners and radiator, better cooling and anti-electrolysis.
