一、引言为了研究钢质量与钢中夹杂物形态和含量的关系,我们对含钛低合金钢中钛的夹杂物形态进行了鉴定和相分离与分析方法的研究。根据文献介绍,钢中钛的夹杂物形态有TiC;TiN;TiO和FeO·TiO_2;TiO_2等,但它们的测定方法,文献中报导不多。有用高硫酸铵-高锰酸钾溶液处理碳化物,在溶液中测定碳化钛,在沉淀中测定氮化钛及氧化钛,较近的文献多数
I. INTRODUCTION In order to study the relationship between the quality of steel and the morphology and content of inclusions in steel, we have studied the methods of phase separation and analysis of titanium inclusions in titanium-containing low alloy steels. According to the literature, the inclusions of titanium in the steel are TiC, TiN, TiO, FeO, TiO 2, TiO 2, etc. However, their determination methods are not widely reported in the literature. Ammonium sulfate - potassium permanganate solution treatment of carbides, determination of titanium carbides in solution, determination of titanium nitride and titanium oxide precipitation, the more recent literature
