摘要
海绵钛产品中的杂质含量是反映海绵钛质量和还原蒸馏水平的一项重要指标,杂质的分布是影响海绵钛等级划分的一个重要因素。采用电感耦合等离子体原子发射光谱法(ICP-AES)测定样品中Fe、Mn杂质的含量。根据已测得的数据,做出了Fe、Mn含量(质量分数)在钛坨中的分布规律图,对钛坨中Fe、Mn杂质的分布进行了研究。结果表明,Fe杂质含量在海绵钛坨中心部分最低,其次是在中心部位的上部和下部,越接近器壁和底部含量越高,底皮和靠近底部的边皮是含铁量最高的部位。Mn杂质含量在海绵钛坨中上部分最低,其次是中上部分的上部和下部,越朝向底部含量越高,底皮是Mn含量最高的部位。
The impurity content in titanium sponge is an important index reflecting the quality of titanium sponge and the level of reduction distillation,the distribution of impurities is an important factor affecting the grade division of titanium sponge.The contents of Fe and Mn impurities in samples were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).According to the measured data,the distribution of Fe and Mn content(mass fraction)in titanium sponge was obtained,and the distribution of Fe and Mn impurities in titanium lump was studied.The results show that content of Fe is the lowest in the central part of titanium sponge,followed by the upper and lower parts of the central part.The closer to the wall and bottom of titanium sponge,the higher the content of Fe.The bottom skin and the side skin near the bottom are the parts with the highest iron content.The content of Mn is the lowest in the middle and upper part of titanium sponge,followed by the upper and lower parts of the middle and upper part.The farther towards the bottom,the higher the content of Mn.The bottom skin is the part with the highest Mn content.
