摘要
对石油钻杆接头水淬热处理技术进行了研究分析。介绍了水基淬火和油基淬火后石油钻杆接头的硬度、硬度均匀性的对比试验;不同条件下的淬火液对钻杆接头冷却速度的影响。研究表明,水基淬火方式能更好地提高钻杆接头马氏体化程度,从而提高淬火质量。
Research analysis was made on the water-quench heat treatment for petroleum drill pipe joint.The paper introduced the comparative test of hardness and hardness uniformity by water-quench and oil-quench processes;and also introduced the effect of quenching liquid to the cooling rate of drill pipe joints under different conditions.The research result shows that the water-quench process can improve the degree of martensite of drill pipe joints with the quality of quench enhancing.
