摘　　要：介绍了我国斜轧管机组包括圆盘轧管机组、精密轧管机组和三辊轧管机组的引进和国内自主设计制造情况;分析了斜轧管机组在迭代发展过程中的改进和创新以及存在的不足;探讨了斜轧管机组装备及工艺技术未来的发展趋势。指出斜轧管机组具有产品壁厚精度高、生产组织灵活、产量适中、投资少,适合于小批量多品种生产的优点,特别是三辊轧管机组在生产中厚壁管品种方面的优势是其他的机组所不可替代的。建议未来要结合轧管新技术、新工艺以及采用智能建造技术,对现有斜轧管机组进行升级改造,并结合自身的优势在专业化品种研发上下功夫。Described here in the paper are the statuses concerning the imported and domestically and independently designed and manufactured rotary-rolling pipe mills like the disc rolling mill,the precision rolling mill and the 3-roll rolling mill in the country.Also analyzed here are the improvement and innovation during the iterative development of the rotary rolling mill,and relevant existing shortcomings.Moreover the future development trend of the equipment and process technology of the rotary rolling pipe mill are discussed.Accordingly it is pointed out that the rotary-rolling mill is in possession of a number of advantages,including high wall accuracy of the product,flexible production organization,proper production output,economical investment and suitability for small batch and multi type production,etc.particularly,the superiority of the 3-roll rotary rolling mill in production of heavy and medium wall pipes,which can not be substituted by any other type of the pipe mill.It is suggested to upgrade the exiting rotary-rolling pipe mills in the future on the basis of the new pipe-rolling technologies,processes and the intelligent construction technology,and to concentrate efforts in R&D of professionalized pipe types based on the pipe-maker’s superiority.
