小口径精密钢管一般以冷轧和冷拔的方式生产,随着小口径高速冷轧机和高速多线冷拔机的应用,实施小口径钢管在线矫直成为可能。其难点在于如何解决经高速冷轧、冷拔并经退火之后的弯曲钢管的无人工干预下的准确上料和主机高速矫直过程中的稳定性问题。中国重型机械研究院有限公司为江苏某厂的30mm无缝钢管生产线提供的精密高速钢管矫直机很好的解决了上述问题,可以作为类似生产线设备的参考。
Small-diameter precision steel tubes are usually produced by cold rolling and cold drawing. With the application of small-diameter high-speed cold rolling mills and high-speed multi-line cold drawing machines, it is possible to implement online straightening of small-diameter steel tubes. The difficulty lies in how to solve the problem of stability in the process of high-speed cold-rolling, cold-drawing and bending steel tube after annealing without human intervention and host high-speed straightening process. China Heavy Machinery Research Institute Co., Ltd. for a factory in Jiangsu 30mm seamless steel pipe production line to provide precision high-speed steel tube straightening machine to solve the above problems, can be used as a reference for similar production line equipment.
