The working process of the mechanical system of the heat treatment quenching and tempering line:

The mechanical action of this complete heat treatment quenching and tempering line adopts PLC control, only need to manually place the bar in the storage rack, and the rest of the actions are automatically completed by the system under the PLC control.

Crane crane material → storage platform → automatic rotating feeding mechanism → feeding roller table → quenching induction heating → infrared temperature measurement → discharge roller table → spraying → quenching completion → tempering induction heating → infrared temperature measurement → discharge Roller table → spray → automatic feeding mechanism → feeding platform → crane hoisting

Selection of power supply frequency for intermediate frequency quenching and tempering heat treatment equipment:

The selection of power frequency follows the principle of better heating efficiency and temperature uniformity (temperature difference between core and surface). The higher the frequency, the higher the heating efficiency, but too high a frequency is likely to cause overburning on the surface of the workpiece. According to theoretical data and our Experience Ø60mm—Ø90mm Choose the quenching frequency 1500HZ-2500HZ to get better heating effect, and will not cause overburning of the workpiece. The tempering frequency of 1000HZ can ensure the uniformity of tempering. Of course, the equipment is designed to match the power and frequency of the power supply for you according to your specific parameters.
