本文对半浸式和全浸式钢管热镀锌的工艺和设备进行了分析比较,认为全浸式具有自动化程度高、双根镀管等优点,但致命的问题是星轮轴使用寿命短,耗损量大。因此,半浸式工艺在我国仍然具有继续使用和推广的实际意义,但应向自动化程度高的方向发展。 In this paper, the technology and equipment of semi-immersion and full-immersed steel hot-dip galvanizing are analyzed and compared. It is considered that full immersion has the advantages of high degree of automation and double-root galvanizing, but the deadly problem is the short service life and wear large. Therefore, the semi-immersion process in our country still has the practical significance of continued use and promotion, but should be to a high degree of automation direction.
