摘要为了提高钢的洁净度，实现夹杂物无害化控制，研究了稀土铈对新型超级双相不锈钢2707HD中夹杂物变性行为的影响。通过热力学计算，初步判定了加入铈后钢液中可能生成夹杂物的类型。利用金相显微镜（OM）、扫描电镜（SEM）、能谱仪（EDS）和Image-Pro6.0软件对钢中夹杂物的尺寸、形貌和类型进行表征和分析。结果表明，当铈的质量分数为0.03%时，钢中尺寸小于1和1～2 μm夹杂物的比例均增加，而大于2 μm夹杂物的比例下降；当铈的质量分数为0.06%时，小于2 μm夹杂物的比例下降，并且有大于5 μm的夹杂物生成。铈使不规则的Al2O3夹杂物变性为规则的Ce2O3和Ce2O2S稀土夹杂物，并伴有Ce2O3-Ce2O2S和CeAlO3-Ce2O2S复合夹杂物的生成，有效减少了钢中不规则夹杂物的数量。

Abstract：In order to improve the cleanliness of the steel and realize the harmlessness control of the inclusions, the effect of Ce on inclusion modification behavior of a new type super duplex stainless steel 2707HD was researched. The possible inclusions generate type in super duplex stainless steel with Ce was preliminary determined by thermodynamics calculation. The sizes，morphology and type of inclusions were characterized and analyzed by metallographic microscope，scanning electron microscope，energy dispersive spectrometer and Image-Pro6.0. The results showed that the tiny inclusions （less than 1 μm） and 1-2 μm inclusions increase，while the proportion of inclusions larger than 2 μm decrease in the super duplex stainless steel with mass percent of 0.03% Ce. The proportion of inclusions smaller than 2 μm decreased，and inclusions larger than 5 μm were formed with mass percent of 0.06% Ce. Ce can transform irregular Al2O3 inclusions into regular Ce2O3 and Ce2O2S rare earth inclusions and accompanied by the formation of Ce2O3-Ce2O2S and CeAlO3-Ce2O2S composite inclusions. Moreover Ce element can effectively decrease the amount of irregular inclusions.
