Quenching and tempering production line

The quenching and tempering production line is mainly composed of an intermediate frequency power supply, a heating sensor, an automatic feeding device, a quick roll discharge device, an infrared temperature measuring device, and a central console. By supporting different inductors, the workpiece can be heated, and the heating temperature and the radial and axial temperature difference can meet the process requirements, and the heat preservation can be realized, and the temperature of each steel pipe can be automatically recorded because the steel rod specification is φ7~12mm< Material 30MnSi> quenching temperature 950℃, so the heating equipment adopts intermediate frequency and super audio multi-frequency mixed heating, and its power and frequency are respectively configured as follows: 250kw/6kHZ (SCR intermediate frequency), 100~200kw/20kHZ, 160kw/50kHZ ( IGBT super audio frequency power supply) tempering temperature of 425℃, 160kw/6 kHZ intermediate frequency power supply, production and operation speed of 50~60m/min (φ9), heating power consumption 300 degrees/ton, all power supplies have internal and external control functions using current medium voltage The double closed loop feature ensures that the quenching and tempering temperature does not change with external factors. Since the production line is in continuous and uninterrupted working mode, the entire production line is controlled by PLC and touch screen, and the actual transmission adopts frequency conversion to schedule and adjust the entire production line. Compared with the traditional slip motor and DC speed control, the control accuracy is high and the adjustment range is Wider and more stable operation.
