中小口径钢管穿孔减径生产工艺

Manufacturing Technique of Punching Reducing of Middle and Small-sized Caliber Steel Tube

介绍了中小口径无缝钢管穿孔后直接减径的生产工艺及该工艺的设备组成,生产工艺的难点及相应的控制措施。该工艺解决了冷拔管生产成本高,效率低,污染大的难题,在低端中小口径无缝钢管中与冷拔管相比极具竞争优势。

The paper was introduced manufacturing technique, equipment composition, difficulties of production process and corresponding control measures of punching reducing of middle and small-sized caliber steel tube. The technology was solved difficulties of high cost, low efficiency and serious pollution of cold drawn pipe production, which had strong competitiveness compared with cold drawn pipe in low-end middle and small-sized caliber seamless steel tube.
