在研究顶吹转炉内气体流动、燃烧和传热的基础上，提出了一个通用的、耦合的数学模型。利用该模型对180 t转炉不同氧枪设计下的二次燃烧率和传热效率进行了计算。所得结果对于了解二次燃烧机理、改进二次燃烧设备以及提高二次燃烧热的利用率具有重要意义。该模型也可推广应用于低泡沫渣层转炉内任意时刻的二次燃烧研究。
Based on the studies of the gas-flow, combustion and heat transfer in the top-blown converter, a general and coupling mathematical model has been proposed. The post-combustion ratio and heat-transfer efficiency in a 180t basic oxygen furnace (BOF) for the different design of oxygen lance were calculated by using this model. The obtained results are very important for understanding the post-combustion mechanism and improving the equipment of the post-combustion as well as raising the utilizing ratio of post-combustion heat. This model can be also extended to study the post-combustion at any time in the converter with a low foam slag layer.
