摘要: 

木文叙述对电解分离低碳鋼非金属夾杂物进行系统试验的结果,并针对现有电解分离夾杂物方法提供了某些改进的意见. 对分离稳定夹杂物而论,试验结果指出用硫酸亚鉄法(一种溶液)进行电解再用过硫酸铵法或硝酸法破坏碳化物是较为适当的;对分离不稳定夾杂物则以用亚硫酸钠法(两种溶液)较为满意. 应用上述方法并结合金相检查对某种低碳结构鋼材进行试验,得到了有意义的结果.

Abstract

Different methods of electrolytic separation of non-metallic inclusions in low carbon steels have been investigated, and certain suggestions for improvement in this connection are proposed.It is shown that for the separation of stable inclusions the more satisfactory procedure is to separate the inclusions and the carbides by the ferrous-sulfate method followed by the dissolution of the carbides either by ammonium-persulfide method or by nitric-acid method, whereas for the separation of unstable inclusions, the sodium-sulfite method gives better results.The modified method supplemented by microscopic examinations has been applied to the study of inclusions in a certain kind of constructional steel with favourable results.
