Product Description:


Application Scope

Steel Bar for Pre-stressed Concrete

Production and processing of PC steel bar (Steel Bar for Pre-stressed Concrete), quenching and tempering heat treatment of metal wire.


Function Structure

      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 inverters driving the mechanism.

     There are totally four sets of heating power supply of PC steel bar production line, the power and frequency of which are designed to be: 600kW/8kHz, 200kW/30kHz, 200kW/50kHz, 300kW/8kHz. The power supply adopts parallel IGBT induction heating power supply. It is just because of online heating that there’re strict requirements concerning working status and synchronization control of the power supply.

      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 diode and IGBT chopper mode. The inverter adopts high voltage large power IGBT module and large power fast recovery diode to form inverter power unit. The resonant tank circuit adopts parallel resonance.

      The whole unit of equipment is composed of four sets of induction heating equipment, water cooling system, console, automatic control system and mechanism system.

 Technical features

Excellent heating power supply design

1.   Power supply cabinet and heating tank circuit adopt independent design with compact structure and small size which is convenient for site layout.

2.  The heating inductor is characterized by high heating efficiency of whole line and stable heating technics by optimization design.

           3.The power supply selects DC chopper mode to ensure the grid side      power coefficient≥0.92 and a relative lower harmonic content.

           4.Adopt      CPLD full digital control system, automatic fixed angle, high precision of      phase-lock and wide scope of phase-lock. Perfect protection function, reliable      working and low failure rate.

           5.High      standard power supply electromagnetism compatibility design and closed      cabinet design to meet the strict requirements at site.


Ø   perfect automatic control of whole line

1. Adopt Siemens S7-300 PLC and colorful touch screen to form whole line automatic control center, which is flexible and high cost performance.

2. Having speed-power automatic matching function, which can realize full scope automatic control to different PC steel bar specification and heating speed.

3. Adopt Siemens for transducer (or specified by the user) and US Raytek for pyrometer.

4. Friendly HMI and fault diagnosis system, which is convenient for operation and maintenance.
