摘　要: 通过试验确定氮气分析流量为9 L/min,静态流量为3 L/min,,冲洗时间为4 s,预燃时间为6 s,积分时间为4 s的激发条件,采用火花源原子发射光谱法测定硅钢中Si、Mn、P、S、Al。采用干扰系数法进行了校正,精密度考察结果表明,相对标准偏差0.50%~4.5%之间。对两块取向硅钢生产样品进行分析,并与其他检测单位进行比对分析,结果一致,且偏差均在允许范围内。

Abstract: Silicon,manganese,phosphorus,sulfur and aluminum in silicon steel were determined by spark source atomic emission spectrometry. The selected excitation conditions were as follows: the analytical flow rate of argon was 9 L / min,the static flow rate was 3 L / min,the flush time was 4 s,the pre- combustion time was 6 s and the integration time was 4 s. After correction by interference coefficient method,precision test was performed,and the relative standard deviations( RSD) were between 0. 50% and 4. 5%. Two silicon steel production samples were analyzed by proposed method and other detection unit,and the found results were consistent. Moreover,the deviation was within the allowance range.
Keywords: silicon steel; spark source atomic emission spectrometry; content
