摘要
通过研究高炉炉缸活性的概念及影响因素,提出合理的鼓风动能不仅是炉缸活性状态良好的前提条件,更是高炉操作者可控的重要的调节手段。通过分析鼓风动能的理论依据和计算方法,得到鼓风动能是随着高炉容积的增大而增大的,合理的鼓风动能需要有合理的风量和风口面积。对高炉在不同鼓风动能条件下所产生的各种直观现象和仪表变化进行了说明,针对这些现象就可以判断出鼓风动能是否在合理范围内,并进行相应的调节。综上,合理的鼓风动能需要适应高炉生产的各方面条件的变化,才能达到长期维护炉缸活性的目的,这就需要对合理鼓风动能进行不断的探索和实践,形成应变的合理的送风制度,确保高炉生产的长期稳定顺行。
By researching the concept and influencing factors of blast furnace hearth activity,the blast kinetic energy that is not only the premise of good hearth activity,but also the controllable and important means to operate the blast furnace for the operator have been proposed.Analyzing the theoretical basis and calculation method of the blast kinetic energy found that blast kinetic energy should be increased with the increase of blast furnace volume,air quantity and tuyere area should meet the satisfaction of reasonable blast kinetic energy.What's more,the various phenomena of blast furnace with different blast kinetic energies were also clearly shown,which could help the operator to judge the blast kinetic energy whether in a reasonable range or not,and adjust accordingly.In conclusion,the reasonable blast kinetic energy must adapt to the change of the various conditions of blast furnace production in order to protect the long-term good hearth activity,which requires constant exploration to form the on-demand and reasonable blast system that could ensure the long-term stability of the blast furnace production.
