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。

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

-6

afer 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.
