摘要
转炉渣、精炼渣试样经自动破碎、磁选、研磨和压片后制成钢环样片,采用X射线荧光光谱仪分析试样中Si O2、Ca O、Mg O、Al2O3、Mn O、TFe、Ti O2、P2O5和S的含量,全过程不需人工操作;通过实验确定了试样制备、分析和设备自清洁的最佳参数。该方法测得各元素分析结果的相对标准偏差(n=10)均小于3%,且分析数据与化学分析法比对误差很小,总用时仅需10 min,适用于炼钢生产过程炉渣试样的快速分析。
It is introduced the fast complete automatic determination of nine components in converter slag and refining slag： Si O2,Ca O,Mg O,Al2O3,Mn O,TFe,Ti O2,P2O5 and S： the two kinds of slag are automatically broken,magnetically separated,grinded,pressed to be made into steel sample ring piece,and then analyzed with X- ray fluorescent spectrometer,without manual operation. The best parameters for sample making,analysis and equipment self- clean are settled. In this method the relative standard deviation（ n =10） of analysis result for various elements is all smaller than 3 percent,and the alignment error between analysis data and chemical analysis method is very small,the total determination time is only 10 minutes. This method is suited to the fast analysis of slag sample in steel making.
