冷辗扩技术在新时期的发展

Development of Cold Ring Rolling Technology in New Stage

随着现代工业技术水平的不断提高,对无缝环件的性能要求越来越高,特别是满足各种使用要求的高性能轴承的需求,其中冷辗扩技术就是制造高质量无缝环件的先进制造技术之一,但还存在许多问题,文章对国内外冷辗扩技术的研究开发情况作了总体概述。

With the improvement of technical level of modern industry, the requirement for the performance of seamless rings is higher than ever. Especially, there is a great demand for high-performance bearings. Cold ring rolling is among the advanced manufacturing technologies to produce seamless ring parts, though there still exist some problems. The research and development of cold ring rolling technology at home and aboard are summarized in the paper.
