关于环境保护的论文：Effect of refining slag containing Ce2O3 on steel cleanliness
Abstract：The effect of pre-melting refining slag containing different contents of Ce2O3 on the absorption and modification of Al2O3 inclusion in an Al-killed steel was investigated through the slag/steel reaction experiment at 1600 ℃.It was found that the replacement of 10 wt.％Al2O3 with Ce2O3 for 50 wt.％CaO-33 wt.％Al2O3-7 wt.％MgO-10 wt.％SiO2 refining slag promoted the slag absorption ability of alumina inclusion,which made the total oxygen content determined by infrared absorption method decrease from 100 to 25 ppm in 15 min.The Mg-Al-Ce-O type inclusion was also detected in the as-solidified samples by scanning electron microscopy (SEM).Thermodynamic analysis indicated that the Ce2O3·Al2O3 type inclusions would be formed with the cerium content in the range of 6.9 ppb to 3.6 ppm when the content of aluminum was 0.01 wt.％. 作者： Author： YANG Xiaohong LONG Hu CHENG Guoguang WU Chengchuan WU Bin 作者单位： State Key Laboratory of Advanced Metallurgy, University of Science and Technology Beijing, Beijing 100083, China 期 刊： 稀土学报（英文版） ISTICEISCI Journal： Journal of Rare Earths 年，卷(期)： 2011, 29(11) 分类号： X757 Keywords： Ce2O3 slag inclusion cleanliness rare earths 机标分类号： TF4 TU5 机标关键词： steel cleanliness scanning electron microscopy refining slag total oxygen content Al2O3 absorption method experiment different type range of analysis ppm would found SiO2 made SEM 基金项目： the National Natural Science Foundation of China Effect of refining slag containing Ce2O3 on steel cleanliness[期刊论文] 稀土学报（英文版） --2011, 29(11)The effect of pre-melting refining slag containing different contents of Ce2O3 on the absorption and modification of Al2O3 inclusion in an Al-killed steel was investigated through the slag/steel reacti...【环境保护的论文：Effect of refining】相关文章：
