How many aspects of energy saving can the crankshaft be heated and tempered?

①The sensor has high efficiency;

②The heating time is short, and the heat transferred from the journal to the heart and the side is small;

③From quenching to tempering station, the crankshaft must be cooled to the loading and unloading temperature. Since the residual heat on the crankshaft is small, the amount of cooling required is also small;

④ Induction tempering is an energy-saving process. Its tempering electric efficiency reaches 96%~98%, and the energy is limited to the shaft neck, not the entire crankshaft is heated and tempered.
