A new type online hardening equipment for quenching has been developed by University of Science and Technology Beijing and Dongbei Special Steel Group in Dalian Special Steel Co., LTD., which consists of strong water jet, medium water jet, weak water jet, air-water spray and side water jet and has flexible cooling and control ability. Based on the equipment, the online quenching process of 718 mould steel is performed by numerical simulation and field experiment. The result of temperature field by numerical simulation agrees well with that of experiment, which can prove that numerical simulation can be very good guidance for field experiment. Experimental tempering hardness difference of 718 mould steel can be controlled within 2 HRC in the whole plate according to numerical simulation. Prediction technology can meet the different cooling rate control and make quenching process comply with preset quenching route to guarantee material microstructure and performance.
