The intelligent distribution model of hot metal based on the mixing process of large and small tanks was established and applied in production practice.The iron and steel balance forecasting model was established through the demand planning of hot metal and the output forecasting of blast furnace.Based on iron and steel balance,the primary and secondary distribution of hot metal is realized by intelligent tank allocation and intelligent scheduling of heavy tank in blast furnace,and the concrete implementation of intelligent distribution of molten metal is completed by intelligent scheduling of locomotives.It has been proved that the comprehensive success rate of the intelligent distribution of hot metal based on the mixing of large and small tanks has exceeded 80%,and the recommended success rate of large tanks has reached 90%.The model successfully addresses the problem of intelligent scheduling of molten metal in the mixing process of large and small tanks,thereby promoting the development of iron-steel interface technology.In the future,through iterative optimization of scheduling algorithms and models,the intelligent level of hot metal scheduling can be further improved.This will promote the green and low-carbon operation of the iron and steel interface,and contribute to the development of intelligent logistics for the national steel industry.
