ժҪ Abstract: Three dimensional finite element flow field model of spraying pipe of roller-type quenching machine is built. The flow field under different structural parameters is computed. After grouping the nozzles, the spraying uniformity is analyzed under different water inlet pipe diameter, different water inlet pipe distance, nozzle diameter, nozzle distance. And the spraying intensity absolute deviation and relative deviation are computed under different conditions. The effect rule of different structural parameters to cooling uniformity is obtained. The results provide theoretical support for improving production quality and optimizing cooling device design.
