Water Jet Quenching Machine Slit Flow Field Simulation and Structure Optimization
Heat treatment quenching machine is one of the key equipments for steel quenching and tempering treatment,whereas water spraying system is an important part of the quenching machine.High pressure outlet is designed to be a slit nozzle,also known as water jet.The water flow distribution uniformity for plate flatness is very critical.In this paper,by simulating analysis based on FLUENT software,the internal flow field distribution was obtained inside the quenching machine.By changing the internal structure of the slit jet,including the exit slit gap,outlet spray angle,flow hole quantity,nozzle length and web,the impact on outlet flow distribution was obtained.Results shows that slit gap,outlet spray angle and nozzle length don”t affect the outlet water flow distribution uniformity significantly,however,flow hole quantity have some degree of impact,whereas web has significant effect.The analysis of the result provides the theoretical reference for the design and optimization of the structure of the water jet.
