无缝钢管三辊斜连轧生产方法及其设备
摘要：
本发明涉及一种无缝钢管三辊斜连轧生产方法及其设备。本发明主要是解决现有无缝钢管的制造方法及设备存在着工艺流程长、生产成本高和占地面积大的技术问题。本发明的技术方案是：一种无缝钢管三辊斜连轧生产方法，其将热轧无缝钢管生产中的穿孔、轧管工序组合成在一个机架上，并采用两组轧辊系统和一套顶头—芯棒—顶杆系统实现穿孔和轧管的连轧工作；所述穿孔和轧管均采用斜轧方法轧制，实现无缝钢管的斜轧连轧生产。一种实现无缝钢管三辊斜连轧生产方法的设备，其包括斜连轧前台、斜连轧主机、斜连轧后台和传动系统，斜连轧前台设在斜连轧主机的前面，斜连轧后台设在斜连轧主机的后面，传动系统与斜连轧主机的穿孔轧辊和轧管轧辊连接。
摘要（英）：

The invention relates to a seamless steel pipe three-roller skew tandem rolling production apparatus. The invention mainly aims to solve the technical problems of high production cost and large floor area of the existing seamless steel pipe manufacturing apparatus. The technical scheme in the invention is that: an apparatus realizing the seamless steel pipe three-roller skew tandem rolling production method comprises a skew tandem rolling foreground, a skew tandem rolling host, a skew tandem rolling background and a transmission system, wherein the skew tandem rolling foreground is arranged in front of the skew tandem rolling host; the skew tandem rolling background is arranged behind the skew tandem rolling host; and the transmission system is connected with a perforation roller and a rolled pipe roller of the skew tandem rolling host.
