Product name: complete set of wire heating equipment

1.PC steel bar production line

PC steel bar production line, also known as prestressed concrete reinforcement production line, is a series of processing such as bending, derusting, drawing, nicking, straightening, quenching and tempering of 30MnSi material reinforcement on the production line, so that all its indexes fully meet the requirements of GB/T5223.3-2005 pipe pile reinforcement.

The PC steel bar production line equipment produced by our company has reached the domestic leading level at present, and the linear speed of four commonly used specifications has reached:

       Φ7.1mm specifications 110m/min

       Φ9.0mm specifications 110m/min

       Φ10.7mm specifications 110m/min

       Φ12.6mm specifications  45m/min

Functional structure

PC steel bar production line equipment has multiple intermediate frequency/ultra-audio power supplies to complete the preheating, heating, quenching and tempering process of steel bars online; Synchronous control of production line process is realized by driving machinery with multiple frequency converters. All the power supplies are IGBT induction heating power supplies in parallel. Because of on-line heating, the working state and synchronous control requirements of the power supplies are strict.

Parallel IGBT induction heating power supply adopts AC-DC-AC variable frequency power supply structure. The rectifier of power supply adopts three-phase thyristor rectification or thyristor +IGBT chopping mode; Inverter adopts high-voltage and high-power IGBT module and high-power fast recovery diode to form inverter power unit; The resonant tank circuit adopts parallel resonance.
