【摘要】 开发了差热抽取测定钢中氧化物夹杂的新方法。考察了一些纯氧化物和钢中不同类型氧化物的分解释氧特征，利用其差异进行分别定量。探讨了精炼过程中夹杂量的下降和改型、钢水二次氧化引起夹杂数量和类型的变化以及分析方法的精度。更多还原

【Abstract】 A new heat extraction method for determining oxide inclusion in steel was developed. The oxygen release feature of some pure oxides and many kinds of oxides in steel were examined, by which differential measurement was completed. The changes of inclusion amount and/or type were studied concerned with refining process as well as reoxidation of liquid steel. The precision of analytical methods was also discussed.更多还原
