典型流程区段炼铁炼钢界面的比较优势研究

运用系统科学还原论和整体论的研究方法,从时间、温度、流量、生产组织、铁水预处理效果、能耗、环境污染等方面分析了六种典型流程区段炼铁炼钢界面技术特点.可以看出六种不同流程区段炼铁炼钢界面各自的比较优势,铁水预处理"三脱"只适合大高炉-大转炉流程区段,其中含转炉脱磷技术的流程更具有优势.指出取消混铁炉、采用铁水包功能多样化和"一包到底"是高炉-转炉界面发展的方向.

Relative superiority research on the ironmaking/steelmaking interface of the typical process section

With the research methods of the holism and reductionism of system science, the ironmaking/steelmaking interface characteristics of the six typical processes were analyzed from time, temperature, mass flow quantity, production plan, the effect of hot metal pretreatment, energy consume, environment pollution and so on. A relative superiority of the ironmaking/steelmaking interface of the six different processes was pointed out. The process ofdesiliconization, desulphurization and dephosphorization is only suitable for the process section of the large-scale blast furnace and the large-scale converter, and the process of dephosphorization in BOF is superior. Canceling the mixer and using the same ladle from BF to BOF are the developing direction of the ironmaking/steelmaking interface.
