摘要
对S135钻杆同种钢材36CrNiMo4A的摩擦焊接、热处理工艺参数及其强韧性进行了试验分析和研究,分析了原有摩擦焊接和热处理工艺造成接头韧性偏低的原因,优化了摩擦焊接和热处理工艺参数,改善和提高了S135钻杆的组织和性能,达到甚至超过了同类产品NKKS135钻杆的组织和性能。
Analysis of the friction welding and heat treatment parameters of compatible steel 36CrNiMo4A, as well as strength and ductility for the drill rod S135 are presented, and the reason of lower ductility of joint welded by original friction welding and heat treatment parameters is described. It was found that microstructure and ductility could be improved by the optimization friction welding and heat treatment parameters for the drill rod S135. The microstructure and property of the drill rod S135 reached and/or exceeded that of the NKK drill rod S135.
