III. Fetures:
The all-solid-state all-digital IGBT induction heating equipment is mainly used for heating galvanized steel wire. After induction heating, it reaches the heating temperature requirement. The complete induction heating equipment includes induction heating power supply (including resonant capacitor, feeding copper bar, pouring inductor, frequency conversion drive, rectifier bridge, inverter bridge and inverter drive part, whole machine). A set of circulating soft water cooling system, heating console, trolly moving system, thermometer, etc.
The efficiency of the power supply is high and the energy saving effect is obvious.
The components are versatile and the whole machine is easy to maintain.
The bridge structure has good flow uniformity.
Full digital circuit, fixed angle control.
