Title:
BLAST FURNACE INJECTION POSITION DETERMINATION METHOD AND TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/060290
Kind Code:
A1
Abstract:
The present invention relates to a blast furnace injection position determination method and terminal device, and a storage medium. The method comprises: adjusting a coke ratio or a coal ratio on the basis of whole-furnace material balance and heat balance; adjusting the injection volume or the oxygen enrichment rate of a hearth on the basis of a degree of direct reduction and stack efficiency; adding injection positions on the basis of the heat balance of a solid furnace charge zone; adjusting the injection volume or the oxygen enrichment rate of the hearth on the basis of the errors between a combustion temperature and blast kinetic energy and initial values; and inputting all the injection positions after adjustment and corresponding injection volumes. According to the present invention, by means of multi-objective optimization, fluctuation of the blast furnace condition caused by a new process is overcome, and the smooth operation and the stack efficiency of a blast furnace are ensured.
