摘要
介绍了一种高炉炼铁新技术即高炉使用热压含碳球团技术,并利用多流体数学模型模拟该操作,对炉内现象和操作性能的变化进行了充分解析。数学模拟结果表明:热压含碳球团的使用将使得炉内温度水平降低,软熔带位置下降,但同时高炉产量增加,焦比显著降低。在一定范围内使用热压含碳球团,高炉热利用效率明显提高,操作性能将有效改善。
In this study, multi fluid model is usea tu ~ operation with charging carbon composite iron ore hot briquette, giving a detailed analysis on in-furnace phenomena and an exact prediction on the operation performance of blast furnace. According to model simulations, with charging carbon composite iron ore hot briquette into blast furnace, the temperature level will decrease in the furnace and the location of cohesive zone shifts downward. On the other hand, the productivity tends to increase while coke rate and total reducing agent rate show decrease. Under charging carbon composite briquette, the heat efficiency of blast furnace improves con siderably and the operation performance of blast furnace is effectively enhanced.
