摘要
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 model to analyze forces on deadman in a hearth under a special condition was constructed and a method to calculate the minimum depth of salamander was put forward. Proved by data from a dissected blast furnace （BF）, the calculation method was perfect. On the base of the former model, a new model for deadman force analysis on the general condition was built, a reliable for- mula to estimate the height of deadman floating was deduced, and the relationship between deadman floating height and liquid slag surface was discussed.
