摘　　要：依据喷水冷却装置的结构建立数学模型,对冷却装置的水流场和温度场进行了数值模拟;研究了大型轴类件喷水淬火过程中水流的冲击距离和喷嘴内径对工件表面换热系数的影响,获得了一些关键的特性参数。The mathematical model was established on the basis of the structure of spray quenching unit,and then the water flowing field and the temperature field in the cooling unit were numerically simulated. The effect of impingement distance of water flow and inside diameter of nozzles on heat transfer coefficient of part surface during spray quenching was investigated. As a result,certain important heat characteristic parameters were obtained.
