科学技术的发展,对冷轧管的品种、数量、质量都提出了愈来愈高的要求。作为轧制工具的轧槽块亦日益为人们所重视。多年来,国内仅对LG-80以下各类小型冷轧管机的轧槽块进行了研制,并取得了显著成效。但是,对于像LG-120、150、200大型冷轧管机的轧槽块则研究甚少,至今质量仍不过关,从而直接影响了大口径无缝管、特别是不锈钢管的生产。因此,研究大型冷轧管机的轧槽块的制造及有关问题,无疑是有重要意义的。本文想以LG-200型冷轧管机轧槽块为例,谈谈当前轧槽块制造中值得注意的几个问题。
The development of science and technology, the cold rolled tube varieties, quantity, quality have put forward higher and higher requirements. Rolling block as a rolling tool is also increasingly valued by people. Over the years, only the domestic LG-80 following various types of small cold rolling mill rolling block has been developed and achieved remarkable results. However, for large cold rolling mill machines such as the LG-120,150,200, few studies have been conducted on the quality of the groove block, which has a direct impact on the production of large-diameter seamless pipes, especially stainless steel pipes. Therefore, the study of large cold rolling mill block production and related issues, no doubt is of great significance. In this paper, LG-200 type cold rolling machine rolling block as an example, talk about the current rolling block manufacturing worth noting several issues.
