The exploration of carbonation routine utilizing BOFs, CRW and CO₂ has a significant effect on terminated treatment of metallurgical wastes resourceful disposal at a low cost. This paper investigated the collaborative effect of CRW composition on slag carbonation degree and CRW decalcification rate in CO₂ sequestration system, furthermore, the effect of reaction time etc. on both were also discussed under optimal composition. Moreover, the carbonation process was simulated by Aspen software for comparing with the experimental results. The results showed that slag carbonation degree and CRW decalcification rate increased as CRW hardness increased, and kept stable. The optimal calcium conversion was 50.4%, corresponding to 15.9g CO₂/100g slag, and the decalcification rate was 87.1%, respectively, at 80 °C and 10 L/kg for 60 min. The Aspen simulation results showed the correlation degrees were 0.94 for calcium conversion and 0.98 for decalcification rate.

利用BOF，CRW和CO ₂进行碳化程序的探索对冶金废物的终止处理具有显着效果，而该废物可低成本地进行资源丰富的处置。本文研究了CRW组成对CO ₂固存系统中炉渣碳化度和CRW脱钙率的协同作用，并在最佳组成下讨论了反应时间等对两者的影响。此外，用Aspen软件模拟了碳化过程，并与实验结果进行了比较。结果表明，随着CRW硬度的增加，矿渣的碳化程度和CRW的脱钙率均保持稳定。最佳钙转化率为50.4％，相当于15.9g CO ₂/ 100 g炉渣，在80°C和10 L / kg的条件下60分钟的脱钙率分别为87.1％。Aspen模拟结果表明，钙转化的相关度为0.94，脱钙率的相关度为0.98。
