In the paper, it is introduced the detection analysis on non-metallic inclusions in rail head. In order to scientifically characterize the quantity, size and distribution of inclusions, the new method for detecting inclusions is explored. A new vertical detection surface is added by taking the sample position with the K method for cleanliness of oxide in the EN 10247—2017 standard, that is, such two sampling methods as vertical plane and inclined plane are adopted separately. The quantity, size and distribution of inclusions in rail head are statistically analyzed with fully automatic optical microscope as well as the compositions of typical inclusions are analyzed with scanning electron microscope and energy disperse spectroscopy. The distribution and sources of inclusions in the rails of Baotou Steel are comprehensively analyzed, which provide technical support for further improving and controlling the cleanliness of rail steel.

文章对钢轨轨头内部的非金属夹杂物进行了检测分析。为科学表征夹杂物的数量、尺寸及分布,探索了夹杂物检测的新方法,参考EN 10247—2017标准中的氧化物洁净度K法取样位置的同时,新增加了一个垂直方向的检测面,即分别采用了垂面和斜面两种取样方法,通过全自动光学显微镜统计分析了轨头内部夹杂物的数量、尺寸及分布,并利用扫描电镜及能谱仪对典型夹杂物进行了成分分析,较为全面地分析了包钢钢轨中夹杂物的分布状况及来源,对进一步提高和控制钢轨钢的洁净度起到技术支撑作用。
