e2O3in chromiumcontaining residue, which can replace limestone anddolomite for industrial production, so the resources are saved and the energy expenditure is reduced. Chromiumcontaining residues are dangerous waste that seriously pollute the ecological environment and harm the humanhealth due to the big output and fierce toxicity. The present processing situation of chromiumcontaining residuesby sintering and ironmaking in our steel enterprises is introduced, and disintoxicating mechanism, technologicalprocess and application practice are analyzed. The way and prospect of prehensive utilization of chromiumcontaining residues in the ferrous metallurgy process are elaborated, and the proposal is put forward.。鉻渣中含有十富的Ca0 .M g0 .Fe2O3等成分,在工業(yè)生產(chǎn)中能代替石灰石、自云石等原料使用,可達(dá)到節(jié)約資源、降低能耗的日的。選課課號: (200920102)BG111916000261 課程類別: 公選課 《冶金工程概論》課程考核(課程論文)題目:冶金過程中產(chǎn)生的鉻渣的危害及無害處理和綜合利用學(xué)生姓名:程曉睿學(xué) 號:2008441148授課教師:張明遠(yuǎn)班 級:應(yīng)化普0802重慶科技學(xué)院冶金與材料工程學(xué)院2010年5月 中國 重慶冶金過程中產(chǎn)生的鉻渣的危害及無害處理和綜合利用程曉睿 應(yīng)化普0802 2008441148摘 要:摘要:在金屬鉻和鉻鹽產(chǎn)品的生產(chǎn)過程中,會產(chǎn)生人量鉻渣,鉻渣毒性劇烈,是嚴(yán)重污染生態(tài)環(huán)境和危害人類健康的危險廢物。介紹了中國鋼鐵企業(yè)利用燒結(jié)、高爐處理鉻渣的現(xiàn)狀,分析解毒機(jī)理、工藝過程和應(yīng)用實(shí)踐,闡述了鉻渣在鋼鐵冶金過程中進(jìn)行綜合利用的途徑和
