Abstract:   One-Ladle-Mode iron-making/steel-making interface technology, which means that hot metal ladles run through the iron-making/steel-making process, is the development direction of iron-making/steel-making interface. To ensure production long-term good running, some problems have to be solved, such as production operation, scheduling, operating preparation, and etc. With the help of logistical simulator, the characters of One-Ladle-Mode iron-making/steel-making interface have been analyzed. A lot of strategies could be provided, such as reasonable hot metal ladles transferring strategies below the iron notch of blast furnace, economic num of hot metal ladles circulating online, optimizing buffer region of hot metal ladles, adequate capacity of casting pig equipment. Because of knowing these strategies in advance, it is help for reach the aim of reducing production costs and keeping the production good running when the One-Ladle-Mode iron-making/steel-making process is put into practice.

Key words: One-Ladle-Mode, Iron-making/steel-making interface, logistic simulation
