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] ......
