摘要
电弧炉短流程作为钢铁行业典型生产流程之一,具有节能减排优势.当前,对碳排放研究主要集中在高炉—转炉长流程,对电弧炉短流程研究较少,而全废钢连续加料电弧炉短流程作为近年来被大力推广的短流程炼钢工艺,其碳排放研究更少.对此,本文以典型全废钢连续加料电弧炉短流程为研究对象,采用碳排放因子法,计算其碳排放情况,并与长流程及短流程不同工艺碳排放量进行对比分析.结果表明:在本研究工艺条件下,全废钢连续加料电弧炉短流程吨钢碳排放量为0.911 t,相比于长流程及其他短流程工艺具有良好减排效果,是钢铁工业实现“脱碳化”的重要途径.通过发展高效化冶炼技术、绿色化生产技术和智能化控制技术等,全废钢连续加料电弧炉短流程还可进一步减少碳排放.
As one of typical steelmaking processes in the industry,the steelmaking process of electric arc furnace(EAF)has the advantage of energy conservation and CO 2 emissions reduction.Recently,the research on CO 2 emissions mainly focuses on the steelmaking process of BF-BOF,and there is little research on the EAF process,let the EAF process with continuous feeding of only scrap has been promoted vigorously in recent years.In this research with the emission factor method,CO 2 emissions in EAF process with continuous feeding of only scrap was calculated,and comparison between BF-BOF and EAF processes was done.The results show that,the CO 2 emission of per ton steel in EAF process with continuous feeding of only scrap is 0.911 t.Compared with the BF-BOF process and other EAF processes,the EAF process with continuous feeding of only scrap has low CO 2 emission,and is an important way to reduce total CO 2 emissions of steel industry.With the development of high-efficiency smelting technology,green production technology and intelligent control technology,CO 2 emissions per ton of steel in EAF process with continuous feeding of only scrap will become lower and lower.
