介绍了连续铸造Φ５０×３７６０ｍｍ细长铸铁冷却管的研制过程，重点介绍了这种细长铸铁管的技术要求及相应的研制设备、拉管工艺和控制铸铁冷却管的变形措施及弯曲变形的矫正方法，实施后不但降低了铸铁冷却管的废品率，而且提高了经济效益。
The development process of continuous casting Φ50 × 3760mm slender cast iron cooling pipe is introduced, and the technical requirements of the slender cast iron pipe and the corresponding research and development equipment, the process of drawing pipe and the control of deformation of cast iron cooling pipe and the correction of bending deformation are introduced Method, not only reduces the rejection rate of cast iron cooling pipe, but also improves the economic benefits.
