| 摘 要： | 通过对非焦煤与铁矿粉“干馏”特征的实验调查分析，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℃，铁矿粉金属化率可达到约85%以上，其中金属铁约60%为氢元素所还原，铁氧化物还原过程约减少CO2排放量可达0.67 t，经济和环境效益显著。 |
| 关 键 词： | 炼铁 非焦煤 氢还原 低碳 |

| Abstract: | 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. |
| Keywords: | ironmaking non-coking coal hydrogen reduction low carbon |
