摘要
通过对非焦煤与铁矿粉"干馏"特征的试验调查分析,提出了"非炼焦煤与铁矿粉"共处理的低碳炼铁预处理技术路线。研究表明:干馏温度800℃,铁矿粉还原度可达到约78%,其中部分金属铁为氢元素所还原,可降低铁氧化物还原过程CO2排放量。
The low-carbon ironmaking technology on co-treatment of non-coking coal and iron-ore fines was proposed through investigating the characteristics of carbonization of non-coking coal and iron ore.The results showed that the percent metallization of the iron ore fines was up to 78% at 800 ℃ of carbonization temperature.Some metallic iron was already reduced by hydrogen,and the amount of CO2 release would be reduced.
