Second, the steel bar quenching and tempering production line process plan

The heat treatment production line is a pipeline type system. The system block diagram is shown in Figure (1). The system can be divided into four parts: electric drive, induction heating, console, data acquisition and other ancillary equipment. The electric drive part consists of 4 motors (1 press machine, 1 tractor, 2 wire take-up machines) and steel bar straightening rollers. Each motor is driven by ABB's inverter; The heating part consists of 4 induction heating machines (2 sets of intermediate frequency power supply, wherein the power of 1# intermediate frequency power supply is P1=500KW, the power of 4# intermediate frequency power supply is P4=250KW. 2#, 3# power supply super audio power supply, power is respectively Composition of P2=320KW and P3=250KW). The 1# thermometer is used to measure the quenching temperature, the 2# thermometer is used to measure the tempering temperature, and finally the shear and line of the PC steel bar. The console is the main control station of the entire production line. The Simens series PLC and touch screen (TP270) jointly monitor the production line.
