管坯斜轧穿孔是热轧无缝钢管生产第一道轧制工序,它对整个机组生产有着重要的影响。在国际上从60年代以来由于对斜轧穿孔方法的生产效率、毛管质量、可穿钢种范围等不断提高要求以及大量使用连铸坯和节能方面的原因,对旧的曼乃斯曼穿孔机不断更新,相继出现了工业应用的三辊穿孔机和带双导盘斜轧穿孔机。单主动导盘斜轧穿孔机是第三个新式穿孔机。
Cross-piercing perforation of hot rolled seamless steel pipe production is the first rolling process, which has an important impact on the entire unit production. In the world since the 1960s due to the production of cross-piercing perforation method, the quality of the capillary, the scope of the steel can be continuously increased requirements and the large use of slab and energy saving reasons, the old manusman punch Constantly updated, have emerged in the industrial application of three-roll piercing machine and with a double-disk cross-piercing piercing machine. Single-lead plate oblique piercing punch is the third new piercing machine.
