低镍高锰铜铝合金轴瓦新材料的研究

Low Ni High Mn Cu-Al Alloy Bush for Hot Plate Mill

从分析热轧薄板机轴瓦的工作特点和失效形式出发 ,论证了采用低镍高锰铜铝合金铸造轴瓦的可行性。采用正交设计方法 ,确定了合金最佳成分。该合金经 82 0℃× 1h淬火 ,其综合力学性能可大幅度提高 ,使用寿命由原来的 36h提高到

The feasibility of casting bush with low Ni high Mn Cu-Al alloy was demonstrated through analysis of the working performance and failure of bush for hot plate mill. The optimized composition of the alloy was determined by orthogonal method. The comprehensive mechanical properties can be improved significantly by quenching at 820 ℃×1 h and the bush service life increased from 36 h to over 72 h.
