| Abstract: | For further research on the control model of multifunctional hot metal ladles between the ironmaking and steelmaking interface,the hot metal ladles of K steel plant were taken as the obj ect to analyze the operation process. The factors of blast furnace supply and basic oxygen furnace demand were proposed.According to the principle of supply and demand balance,the control model of hot metal was researched under the following factor conditions:equal to,greater than,and less than 1 ,respectively.The distribution model of the blast furnace,steelmaking works,and online buffering was proposed.When the supply and demand factor is equal to 1 ,the turnover number of hot metal ladles equals 1 6 and the turnover cycle of hot metal ladles equals 5 1 2 min.When the factor is greater than 1 ,the total number of hot metal ladles is equal to the normal turnover number plus the turnover number of the cast iron machine.When the factor is less than 1 ,the total number of hot metal ladles is equal to the normal turnover number plus the accumulating number.Satisfactory effects were obtained by applying the control model in produc-tion.The numbers of turnover ladles and accumulating ladles were reduced. |
