EAF-LF(VD)-CC工艺生产石油管线钢39Mn2V纯净度的分析
An Analysis on Cleanliness of Pipe Line Steel 39Mn2V for Oil Field Produced by EAF-LF(VD)-CC Process
【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A l2O3、MnS、球形铝酸钙,尺寸≤20μm。铸坯存在一些80~300μm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 of EAF-LF(VD)-CC process have been analyzed and studied.The results indicated that the(T[O]) was 28×10-6 after LF(VD) refining and the(T[O]) of cast billet was(810) ×10-6;and the inclusions in steel were mainly Al2O3,MnS,spherical calciumaluminate with size ≤20 μm.there were some inclusions with size 80300 μm which originated from secondary oxidation,refractory material erosion and slag entrapment in mold.
