Spring wire water tempering production line with induction heating
I. Whole Work Flow:
Pay off → Pinch rolls set No. 1 → HV-Straightener → Pinch rolls set No. 2 → Cleaning unit → Induction Quenching No.1 → Induction Quenching No.2 → Induction Quenching No.3 →Heat holding → Jet-cooling for Quenching → Induction Tempering →Heat holding → Jet-cooling for Tempering → Flaw detector → Pinch rolls set No. 3 → Oiler → Shearing → Wire separating → Wire take-up
II. Main Technical Parameters:
||steel grades SiCr and SiCrV classes FD, TD, VD
||φ8,0 - φ16,0 mm
||Induction quenching temp.
||≤1000ºC constant and adjustable (920-1000ºC)
||Induction tempering temp.
||≤650ºC constant and adjustable (450-650ºC)
||Temp. control accuracy
||Take-up coil dimension
||Max. Take-up coil weight
||1) Spring wires produced by this production line would keep uniform and straight;
2) Products keep consistence with EN10270-2:2011, tensile strength fluctuation of the same coil of spring wire would be ≤50MPa
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.
