大型铝合金环形件轧制过程中爬辊扭曲问题研究

Study on Creeping and Distortion Problems in Large-Size Aluminum Alloy Ring Rolling Process

分析了大型铝合金环形件轧制过程中出现爬辊、扭曲问题的主要原因,根据试验研究提出了解决爬辊、扭曲问题的方法和措施。在国产首台5m 径-轴向数控轧环机上的生产实践证明,所提出的解决方法是切实可行的。

The causes of creeping and distortion in the large- size aluminum alloy dng rolling process are analyzed, and the methods and measures to resolve these problems are proposed based on the experimental investigation. The practical production on the first homemade 5 m NC radial- axial ring- rolling mill shows that the proposed methods are practical and effective.
