| 摘 要： | 介绍了南钢在3500炉卷轧机上研制开发的X65管线钢板的生产工艺与产品性能.研究结果表明:将管线钢的碳的质量分数控制在0.07%以内,适当加入Nb、Ti和Mo等微合金元素,并控制P和S的质量分数分别低于0.013%和0.002%,在3500炉卷轧机上采用TMCP工艺,可以获得高强韧的针状铁素体型管线钢板,各项力学性能指标甚至可以达到X70的水平.此外,所研制的X65管线钢管具有良好的力学性能和焊接性能.

| Abstract: | The production technology and mechanical properties of X65 pipeline steel plate produced by 3500 steckel mill at Nanjing Iron & Steel United Co.are introduced.The results show that using TMCP technology,the X65 pipeline steel plate produced can obtain an acicular ferrite microstructure and strength and toughness equal to that of X70 steel.In X65 steel the content of Nb,Ti and Mo should be reasonable,C content must be less than 0.07%,P and S less than 0.013% and 0.002% respectively.In addition,X65 steel has good weld-ability. |
