首发时间:2020-03-24
摘要:建立了转底炉中含碳球团直接还原耦合多相反应动力学的数学模型,采用计算流体力学软件并定义球团比表面积δ作为不同形状球团的关键特征参数,分析了形状对球团直接还原过程的影响,最后对球团还原的DOM和ZRR结果进行了拟合。结果表明,在还原时间0 s For information in English, please click here Effects of carbon containing pellet shape on its direct reduction process in rotary hearth furnace: a numerical study Abstract:A mathematical model for the kinetics of coupled reduction of carbon-containing pellets in a rotary hearth furnace was established. Computational fluid dynamics software was used, and the specific surface of unit volume δ of the pellet was defined as the key characteristic parameter of the different shapes. The influence of the shape on the direct reduction process of the pellet was analyzed, and finally the DOM and ZRR results of the pellet reduction were fitted. The results show that in the range of reduction time 0 s Keywords:
