The Converter Intelligent Steelmaking Model Project was formally launched in March 2022, and it is a practical project of intelligent model application in the "14th Five-Year Plan of Informationization and Intelligent Manufacturing of Jingtang Company" led by the Operation Department of Jingtang Digital Intelligence, jointly developed by the Steel Rolling Operation Department, the Institute of Intelligent Manufacturing, and the technical staff of Shouxin Company. The project team of 30 core personnel took 20 months to complete the research and development and online task of the six modules of "automatic steel discharge from the converter, automatic slag sputtering, automatic slag discharge, flue gas analysis, oxygen gun linkage, and ladle quality grading".

The model is a converter intelligent smelting expert system composed of the oxygen lance linkage system, flue gas analysis system, and sub-lance system. The automatic steel discharge module is deeply integrated with the steelmaking post, and the angle of the converter can be automatically tilted according to the position of the steel car and the weight of the steel during the steel discharge process. The automatic slag sputtering module of the converter further standardizes the operation of slag sputtering and furnace protection through intelligent control, realizes the uniformity of the slag sputtering effect, and provides the guarantee for the stability of the furnace age and the smoothness of bottom blowing. The automatic slag discharge module of the converter controls the linkage between the converter and the slag truck by adopting mechanical vision instead of human eyes, which ensures the safety and efficiency of slag discharge and reduces the labor intensity of personnel.

At present, all six modules of the Smart Steelmaking Project are in operation in the Jingtang No. 8 converter.
