Analysis and optimization of system dynamic operation at iron-making and steel-making interface under"one ladle from BF to BOF"mode
The"One-ladle-from-BF-to-BOF"mode at the iron-making and steel-making interface is conducive to im-proving the operation turnover efficiency of the ladle and reducing the temperature drop during transportation and carbon emission.To give full play to the advantages of this technology,the system dynamics method for optimiza-tion of iron-making and steel-making interface operation in BF-BOF long process was studied based on the theory of metallurgical process engineering.Focusing on the influence of ladle turnover number,transportation time and iron temperature drop,the dynamic variation characteristics of ladle operation in the region under the action of"push"in BF process and"pull"in BOF process,as well as the relationship between the reasonable number of ladle and the change of inlet and outlet rate in the interface interval,were analyzed.The simulation model based on Flexsim was established to optimize and analyze the influencing factors,and the optimal configuration scheme of ladle was ob-tained.The research method provides the optimal means and basis for promoting the balance of supply and demand of ferric material flow and improving the efficiency of interface operation.
