s2, identifying the number of heavy cans on the way transported to each steel-making area can pouring station and the number of heavy cans in stock corresponding to the can pouring station;
s3, carrying out heavy tank transportation planning on the heavy tank filled with molten iron;

s5, carrying out molten iron pouring operation on the heavy cans transported to the can pouring station;
and S6, executing empty tank transportation planning on empty tanks after pouring molten iron, and turning to S1.
In step S1, during charging molten iron, the computer device in the blast furnace area recognizes the temperature and type of the molten iron currently charged, and combines the temperature and type of the molten iron with the number of the empty can recognized by the RFID recognition device at the tap hole of the blast furnace, and at this time, molten iron information corresponding to the number of the can is formed.
And step S2, identifying the current heavy ladle in the transportation process and the inventory molten iron amount of a ladle pouring station in the steelmaking area, and determining the requirement condition of each steelmaking area for molten iron, and providing data support for the heavy ladle transportation plan in step S3, wherein when the RFID equipment at the outlet of the blast furnace area detects that the heavy ladle is driven away from the blast furnace area, the data processing unit marks the heavy ladle as a heavy ladle in the way, and simultaneously identifies the destination of the heavy ladle, and the total number of the inventory molten iron tanks and the molten iron in the way of the ladle pouring station in each steelmaking area can be calculated at the moment, so that the requirement degree of the current steelmaking area for molten iron can be judged through the total number.
