建立了一个特殊情况下死焦堆在炉缸中的受力模型,推导出了最小死铁层深度的计算公式,并用某高炉解剖数据进行了验证,结果表明该模型可靠.在此基础上提出了一般条件下的死料柱受力模型,推出了一个用于估算一般情况下死焦堆浮起高度的公式,并讨论了死焦堆浮起高度与炉渣液面高度的关系.
A stress model of dead coke piled up in a hearth under special circumstances was established, and the formula for calculating the minimum depth of the dead iron layer was derived and verified with the data from a blast furnace. The results show that the model is reliable Under the general conditions of the dead-column stress model, a formula for estimating the height of the dead-coke pile under normal circumstances is introduced. The relationship between the height of the dead coke pile and the height of the slag liquid surface is discussed.
