A)PC Steel Bar Production Line

PC steel bar production line, also known as pre-stressed concrete steel bar production line, 30 MnSi steel material is on the production line for bending derusting drawing notch, straightening, hardening, tempering, and a series of processing, each index to make it fully meet the requirements of GB/T 5223.3-2005 pipe pile reinforcement.

Currently, our company PC steel bar production line equipment has reached the domestic leading level, four kinds of commonly used specifications linear velocity have been reached:


Φ 7.1 mm 110 m/min

Φ 9.0 mm 100 m/min

Φ 10.7 mm 70 m/min

Φ 12.6 mm 45 m/min

PC steel bar production line is complete automatic control: several sets of medium frequency/super audio frequency power supply accomplish pre-heating, heating, quenching and tempering of steel bar online. Realize synchronization control of production line by several sets of frequency converter driving the mechanism.Power supply all adopt parallel IGBT induction heating power supply. Because it is online heating, the working state of power supply and strict synchronization control.

The parallel IGBT induction heating power supply adopts AC-DC-AC variable frequency power supply structure. The rectifier of the power supply adopts 3-phase thyristor rectifying or SCR and IGBT chopper mode. The inverter adopts high voltage large power IGBT module and l
