Research on Cost Control Expert System for Converter Steelmaking Process
The long smelting process of converter steelmaking process is complicated,and it is difficult to update the smelting cost of each process in time,which brings difficulties to real-time cost calculation.In this study,the cost control expert system of integrated converter steelmaking process is established based on C/S software architecture through the integration research of the BOF-LF-VD production process,combined with the cost control model and the actual operation of process optimization.The expert system establishes the main interface of steelmaking cost control and process optimization,optimizes the process in real time by adjusting production parameters,establishes the control module of the end temperature of converter,LF and VD furnaces,forecasts and controls the end point of steelmaking in real time,establishes the optimized dosage control system of LF furnace alloys,and records the yield of alloying elements in the smelting process of LF furnace in real time.Establish cost control and optimization module to forecast and monitor production cost in real time.The online operation results show that the cost of converter process and LF process is reduced by 15.6 yuan/t and 12.4 yuan/t respectively,and the total average cost is reduced by 28.0 yuan/t,which effectively solves the cost control problem of converter steelmaking process and improves economic benefits.
