| 摘 要： | 根据钻杆焊缝局部喷雾淬火的特点，设计了新型的喷雾冷 装置。生产试验表明，该装置能完全适应生产需要，处理后焊缝区的冲击韧度值可达４００Ｊ／ｃｍ＾２建立了合理的数学模型，用有限元方法计算了喷雾淬火过程中温度场随时间的变化规律，计算结果与试验结果吻合。

| Abstract: | In order to improve the shock toughness of friction welding joint of oil drilling pipe,spray quenching is used as the measure of heat treatment after friction welding.A new type of equipment has been designed for the heat treatment process,which has been successfully examined on manufacturing line.With this equipment,the shock toughness was about 400J/cm 2 after heat treatment in the welding area A reasonable mathematical model is established to calculate the temperature field with time during quenching,and the change of microstructure is considered The calculation results agree well with the experiment |
