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. Wood article describes the results of systematic experiments on the electrolytic separation of non-metallic inclusions in low-carbon steel, and provides some suggestions for the improvement of existing methods for the separation of inclusions by electrolysis.For the separation of stable inclusions, the experimental results indicate that Sulfate method (a solution) for electrolysis and then ammonium sulfate method or nitric acid destruction of carbide is more appropriate for the separation of unstable inclusions with sodium sulphite method (two solutions) are more satisfied with the application of the above Method and combined with metallographic examination of a certain type of low-carbon structural steel test, get a meaningful result.
