摘　　要：对典型规格的精密轧制无缝钢管的力学性能、加工工艺性及推广经济性同传统热轧无缝钢管、冷拔精密无缝钢管进行对比分析。试验结果表明,3种无缝钢管规格相同时,精密轧制无缝钢管具有最佳的综合力学性能,与传统热轧无缝钢管相比可大幅缩短加工时间,同时成本可降低约2%;与冷拔精密无缝钢管相比,其加工效率相同,成本可降低约13.6%,具有在矿用油缸制造中推广应用的广阔前景。A comparative analysis was conducted on the mechanical properties,processability,and economic viability of precision rolled seamless steel tubes of typical specifications versus conventionally hot-rolled seamless steel tubes and cold-drawn precision seamless steel tubes.Experimental results show that when the three types of seamless steel tubes have the same specifications,the precision rolled seamless steel tube exhibits superior comprehensive mechanical properties.Compared with traditionally hot-rolled seamless steel tube,it significantly reduces processing time while also decreasing costs by approximately 2%.When compared with cold-drawn precision seamless steel tube,they have the same processing efficiency but cost about 13.6%less,indicating good prospects for promotion and application in the manufacture of mining hydraulic cylinder.
