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