摘　　要：铬渣是社会公认的有害工业废渣,青钢通过烧结技术改造,以铬渣代替部分熔剂,完成了青岛市存贮数十年,总量达20余万t铬渣消化任务。介绍了铬渣处理的依据、技术方案存在的问题及解决措施,并对应用效果进行了分析。铬渣消化过程中代替部分白云石和生石灰,其固有的黏性改善了混合料的制粒效果,促进了烧结生产的顺利进行。同时周边居民生活环境得到显著改善,逐步降低地下水污染的危害,具有明显的经济效益和社会效益。The chromium slag is a kind of acknowledged harmful industrial waste slag. The chromium slag over 200 thousand tons, accumulated in Qingdao for decades, is digested in Qing Steel by sintering technical reformation and using the slag to substitute part of flux. It is introduced the reliance, problems in technical plan and the solving measures in treating procedure, analyzed the application effect. The chromium slag is used to substitute part of dolomite and quick lime, its inherent viscidity improves the grain - making effect of mixing materials and promotes steady sintering production. At the same time the living environment round gets obviously improved, the harm of pollution of underground water is gradually weakened, great economic and social profit got.
