摘　　要：铁水样品经特制取样器取样,再经过白口化处理,使用杯形砂轮磨样机磨削制样,在荧光分析仪上建立分析曲线,用X射线荧光光谱法测定铁水中Si、Mn、P、S、Cr、Ni、Ti、As等元素。通过对磨削深度、方法精密度、方法准确度的讨论,发现该方法具有分析速度快,少化学废物的产生,生产成本低,降低能耗及分析人员的工作强度等优点,分析结果的精密度、准确度完全能够满足连续生产要求。Taken from hot metal with special sampler,the sample is subject to white treatment and is ground by annular wheel sample grinder to be prepared into specimen.Analysis curve is established on fluorescence analyzer and elements of Si,Mn,P,S,Cr,Ni,Ti,As and others are measured and determined with X-ray fluorescence spectrometry.Discussion on grinding depth and the precision and accuracy of the method finds that this method,with advantages of fast analysis speed,less chemical waste generation,low production cost,less energy consumption and reduced labor strength,meets the continuous production requirements with precise and accurate analysis results.
