摘要
本文研究了火花光源-原子发射光谱法测定碳素结构钢化学成份的最佳条件,根据单道扫描型光谱仪自身的特点,选择预燃时间和积分时间,并研究了钢坯及轧制成材化学成份的均匀性。将建立的校准曲线应用于进口及国产标样的测定,获得准确结果,将本方法应用于几种实际样品的测定,结果与国家标准方法吻合。对三个含量织样品的精密度实验中,连续重复精密度RSD≤5.24％;断续重复精密度基本上RSD≤5.78％;再现精密度RSD≤7.82％。
The method dealt with in this paper studied the most suitable analysis condition for carbonic structural steel analysis by spark-atomic emission spectrum method. According to the characteristic of sequentinl spectrometer, selected pre-spark and spark time, and studied the elemental uniformity in steel billet and rolled products. Applying this method to the analysis of standard and steel sample,results are satisfactary, and to samples which include 3 levels of carbon content.accuracy result are also satisfying.
