Kako to induction heating furnace quenching of disk-shaped thin parts raditi?

Figure 8-37 shows a hardening machine bed for thin disc-shaped parts. The induction heating furnace uses high-frequency power supply and disc-type sensor for quenching. The workpiece can be rotated or not. The quenching mechanism is pneumatically lifted. After heating, the workpiece is removed and immersed in the quenching cooling medium for quenching. In order to improve productivity, the power supply has dual output alternate working function
