摘　　要：采用商业软件Fluent对软熔带焦炭熔损反应进行了数值模拟,阐明了影响焦炭反应速率的主要因素,分析得到以下结论:焦炭反应速率随着焦炭粒度的增大而减小,随着入口气体速度的增大而减小;焦炭反应速率随着温度的增加而增加,随着CO2体积分数的增加呈线性关系增加。The carbon loss reaction of coke in cohesive zone of blast furnace under different conditions is studied using commercial software Fluent in this paper.The following conclusions are drawn：the rate of carbon loss reaction decreases with increase of coke size and the velocity of inlet gas,and it increases with increase of temperature and volume fraction of CO2,and there is a linear relationship between the rate and volume fraction of CO2.
