| 摘 要： | 通过在模拟高炉温度和煤气成分变化的条下,对我国重点钢铁厂铁矿石还原及焦炭气化的藕合反应研究,阐明了焦炭气化与铁矿石还原与反应历程有关。分析预测高炉冶炼效果除考虑恒定温度和恒定煤气成分下焦炭与铁矿石冶金性能外,还应考虑焦炭与铁矿石藕合反应过程CO过剩量。研究表明宝钢、首钢、本钢、鞍钢CO过剩系数ηc较小,煤气利用好;包钢、重钢和梅山冶金公司ηco较大,煤气利用较差。

| Abstract: | This paper studies on the coupled reaction of coke gasification-iron ore reduction in majors of iron and steel corporation in China, simulating the behaviour of blast furnace dependenting on gas composition and gas temperature. It was found that the reaction charateristics of the coke gasification-iron ore reduction were markly affected by its history. The efficiency of blast furnace should consider the imbalance between CO produced by coke gasification and CO consumed by iron ore reduction. |
