摘　　要：针对27SiMn热轧无缝管生产液压缸缸体各种工艺路线的不足,开发出XYQ420热轧无缝管。对比分析XYQ420的化学成分、热轧管及冷拔管的力学性能,结果表明XYQ420冷拔管的抗拉强度与27SiMn冷拔管相当,但XYQ420冷拔管的塑性韧性指标大大优于27Si Mn冷拔管。采用XYQ420高强韧性冷拔管生产高压油缸缸体可有效减少缸体爆裂发生的概率,拓展冷拔管在液压缸行业的应用范围,有效提高液压缸的整体质量水平。To the questions of 27 Si Mn seamless tube in making hydraulic cylinder casing technologies, the XYQ420 seamless tube was developed. The chemical composition/mechanical property of XYQ420 tube was researched contrastively. It shows that the tensile strength of XYQ420 cold-drawn tube and 27 Si Mn cold-drawn tube are comparatively, but the toughness of XYQ420 cold-drawn tube is much better.The application of XYQ420 cold-drawn tube in cylinder casing will reduce the probability of casing crack, promote the application filed of cold-drawn tube in hydraulic cylinder, so as to the quality level of hydraulic cylinder.
