| 摘 要： | 在Φ１００ｍｍ自动轧管机组上，通过改变穿孔轧辊辊型参数和穿孔顶头尺寸，调整穿孔工艺，实现大角度、低转速穿孔速度制度，以及重新设计厚壁管专用定径孔型等技术措施，成功地开发了汽车轴头用Φ９８ｍｍ×２２ｍｍ３０Ｍｎ２热轧厚壁钢管。该产品各项质量指标符合有关标准要求，目前已投入批量生产。

| Abstract: | The Φ98mm×22mm 30Mn2 hot-rolled heavy-walled steel tube for auto-spindle nose has been developed with the Φ100mm plug pipe mill line,via such technical measures as changing parameters for the piercer roll groove and dimensions of the piercing plug,adjusting the piercing process,using large angle-low RPM piercing speed schedule as well as redesigning the special pass for sizing of the heavy-walled tube.Massive production of the said tube which has all of its quality indexes up to relevant standard has been started. |
