How is the quenching of crankshaft induction heating furnace developed?

The German induction heating equipment manufacturer developed induction hardening technology for rotating crankshafts earlier, from immersion quenching to spray quenching, from semi-automatic induction heating furnace quenching to fully automatic induction heating furnace quenching, from heating one journal to multiple journals at a time , From a fixed crankshaft size to flexible and variable sizes, from manual sensor change to automatic sensor change, from one immersion tank to multiple immersion tanks, many improvements have been made. Figure 8.15 shows the development process from semi-automatic crankshaft induction hardening machine tool to fully automatic flexible crankshaft induction heating furnace hardening.
