摘要
建立基于多相热流耦合的高炉瞬态过程数学模型,解析多相态在高炉中流场及热传递情况,并通过模拟得到炉料瞬态温度分布结果,由此可方便地判断高炉内软熔带等重要区域的形状及位置。充分解析了各个相态之间的耦合作用,并对高炉中存在的主要化学反应做了适当处理。所建立数学模型和数值计算方法形成了较完整的、适用于国内高炉的过程分析及预测模式。最后,通过对某中型高炉的生产实例分析讨论了该模型的仿真性能。
The blast furnace （BF） transient mathematical model based on multiphase coupling was built, in which the motion and heat transfer of muhiphase in BF was solved. Through computational visualization, the model simulated transient results of per-phase could be got, which made it easy to estimate the profile and position of cohesive zone. The model considered the simple chemical reactions and analyzed the coupled relationships of phases. The BF mathematical model, the computational visualization formed a process analysis and prediction system, which was a guidance on actual BF operation. Finally, the performance of transient model was verified through simulating one BF process.
