摘　　要：钢样表面质量对直读光谱仪的分析结果有较大影响,但钢样表面粗糙度对分析精密度的影响鲜有探讨。通过选取不同含量范围的中低合金钢标样、改变钢样表面粗糙度,对直读光谱仪分析C、Si、Mn、P、S五大元素的精密度行了探讨。试验结果表明:中低合金钢表面粗糙度对C、Si、Mn、P、S分析精密度有显著影响,且粗糙度在2~4μm左右能获得更好的分析精密度。The surface quality of steel sample has a great influence on the analysis results of direct reading spectrometer,but the influence of steel sample surface roughness on the analysis precision is rarely discussed.The precision of direct reading spectrometer for the analysis of carbon,silicon,manganese,phosphorus and sulfur is discussed by selecting standard samples of medium and low alloy steel in different content ranges and changing the surface roughness of steel samples.The test results show that the surface roughness of medium and low alloy steel has a significant effect on the analytical precision of carbon,silicon,manganese,phosphorus and sulfur,and the roughness from 2μm to 4μm can obtain better analytical precision.
