中直径ERW机组单卷和连续生产工艺的优缺点分析比较(下)

Analysis and Comparison Concerning Advantages and Disadvantages of Single-forming Process and Continuous Forming Process for Medium-sized ERW Pipe Mill(PartⅡ)

对中直径ERW机组是采用单卷生产工艺还是连续生产工艺,在国内焊管界存在较大的意见分歧。从产品规格、技术先进性、年生产能力、金属收得率、产品质量、能源消耗、投资等多个方面对单卷生产工艺和连续生产工艺进行分析比较,认为中直径ERW机组采用单卷生产工艺比连续生产工艺更具有优势,建议在建设中直径ERW机组时多采用单卷生产工艺。

In domestic weld-pipe industrial circles, there exists a debate concerning a proper choice for the ERW pipe mill to be made between the single-forming process and the continuous forming process. Analysis and comparison respecting to these two processes are made in terms of product lines, technological advancement, annual capacity, yield, product quality, energy consumption and investment scale, etc. As a result, it is concluded that the single-forming process will enable the ERW mill to be more technologically superior than it would be in case of the continuous forming process, and accordingly it is proposed for future ERW mill line builders to adopt the single-forming process as the most possibly alternative.
