摘要
介绍了利用光谱仪分析钢中夹杂物技术的原理.通过对光谱仪原始脉冲强度的研究,建立了Al2O3光谱强度与化学分析含量的工作曲线,确定了光谱强度与夹杂物粒径的关系,实现了Al2O3含量和粒径分布的快速分析.与化学分析相比,分析误差平均为3×10-6,夹杂物含量和粒径的分析时间由2～5d缩短到5min,为炼钢及精炼过程夹杂物控制提供了有效技术手段.
The principle of analyzing inclusions in steel by spectrum instrument was presented. The curve of AlzO3 pulse intensity by spectrum with its content by chemical analysis was established based on studying original Al2O3 pulse intensity from spectrum instrument, the relationship between the spectrum intensity and the inclusion size was determined, at last A12O3 content and size distribution analysis on-line was realized. In comparison of chemical methods, the average error of the spectrum method is 3 × 10^-6. The time of analyzing the inclusion content and size was shortened to 5 min from 2 - 5 d, which can offer a effective inclusion analysis technique for inclusion on-line control in steel-making and refinement processes.
