摘要
对大型渗碳钢齿轮轴锻件表面出现的磁粉检测质量问题进行分析,发现缺陷为Al、Ca、Mg、O等主要成分形成的复杂氧化夹杂物,通过采取降低产品全氧含量和防止外来夹杂物等措施,成功解决了大型齿轮轴锻件的磁粉检测质量问题。
The magnetic particle testing quality issue appeared on the surface of heavy carburizing steel gear shaft forgings has been analyzed. It shows that the defect was a kind of complicated oxide inclusion which was mainly composed of Al, Ca, Mg and O. By adopting the measurements of reducing the total oxygen content of product and preventing the foreign inclusion, the magnetic particle testing quality issue of heavy carburizing steel gear shaft forgings has been solved successfully.
