="ChDivSummary" name="ChDivSummary"><正>A copper converter slag was examined chemically and mineralogically to determine its existing phases, in particular those containing Co and Cu. The slag consists predominantly of fayalite and magnetite, together with some glass, chalcocite, and metallic copper. Copper is entrapped in the slag mostly as chalcocite and metallic copper, as well as trace copper......

利用铬渣制备耐火材料 谢静1,孙加林1,薛文东1,李勇1 (1.北京科技大学,北京,100083) 摘要:从铁合金生产中排出的是一种有害废渣,而且排放量日益增加,对环境造成极大危害.本研究采用铁合金厂排放的含铬废渣,将废渣与镁砂以不同比例混合,测试了试样的体积密度,气孔率,常温耐压强度等常温性能,并用电镜对部分试样进行显微结构观察和矿物成分分析.结果表明:铬渣镁砂复合耐火材料的生产是可行的,在经过烧成后材料中生成大量的尖晶石和镁橄榄石相,试样的性能良好,完全可满足耐火材料使用的要求.当铬渣的加入量超过40%(质量分数, 下同)时,复合材料的性能下降较大,综合各项指标来看,为保证使用性能,铬渣的加入量应小于40%. 关键词:铬渣; 耐火材料; 制备; chromium slag; refractory; preparation; [全文内容正在添加中] ......
