Abstract

Abstract: The total oxygen content(T[O]),nitrogen content([N])and non-metallic inclusion in steel 39Mn2V at each phase&n of EAF-LF(VD)-CC process have been analyzed and studied. The results indicated that the T[O] was 28×10^-6afer LF(VD)refining and the T[O] of cast billet was(8~10)×10^-6;and the inclusions in steel were mainly Al₂O₃,MnS,spherical calciumaluminate with size ≤20 μm. there were some inclusions with size 80~ 300 pm which originated from secondary oxidation,refractory material erosion and slag entrapment in mold.

摘要： 分析和研究了EAF-LF(VD)-CC各工序39Mn2V钢的T[O] 和[N] 以及钢中非金属夹杂物。结果表明，LF(VD) 后T[O] 为28×10^-6,铸坯T[O] 为(8~10)×10^-6 ;钢中夹杂物主要为Al₂O₃、MnS、球形铝酸钙，尺寸≤20 μm。铸坯存在一些80~300 μm 夹杂物，主要来源于二次氧化、耐火材料侵蚀和结晶器卷渣。
