低铬铸球的失效分析及改进前景

Failure Analysis of Low Chromium Cast Iron Balls for Pulverizers and Their Improving Prospect

对实际工况条件下的低铬铸球进行了金相、机械性能及磨面扫描电镜的分析,提出了此种磨球在实际工况条件下的失效机制及改进前景。

In this paper, the property of low chromium cast-iorn balls under actual working condition was analyzed by means of metallurgy, mechanical property and electric scanning microscope observation over ground surfaces. The failure mechanism of mill balls under this kind of working condition and improving prospect were proposed.
