摘要: 详细介绍了我国无缝钢管技术装备的发展情况。我国自1953年建成投产Φ140mm自动轧管机组以来,通过开发、研制以及引进,目前已是世界上拥有热轧管机组种类和规格最齐全,冷拔、冷轧管机的种类、规格也较齐全的国家,但装备水平参差不齐,设备设计、制造力量分散。提出了我国应充分发挥现有先进装备的特长,加速开发小型先进装备,改造部分现有的一般轧管机组,调整其分布,提高企业集中度,组建大型无缝钢管集团公司,使我国从无缝钢管大国向无缝钢管强国发展的建议。Abstract: The technical equipment development of domestic seamless steel tube-making industry is detailed. Since 1953 when the first domestic mm plug mill was put into operation, thanks to continual research, development and import, the seamless steel tube-making industry of the country has been equipped with the most complete hot-rolling mills in the world in terms of type and product size range, and also equipped with cold-rolling(drawing)mills with consi-derable type variety and tube size range. However, the technical equipment level so varies geographically, and the equip-ment engineering and manufacturing firms are so scattered. To speed up the domestic seamless steel tube-making indus-try and turn the country from a big seamless steel tube consumer and producer into a world power in this regard, proposals have been put forward, including fully tapping the capacities of the existing advanced equipment, gearing up develop-ment of small modern mills, making distribution of the conventional pipe mills more geogr aphically logical and impr-oving the centralization of the manufacturers as well as building up large-scale corporations.
