Slag Forming Coefficient and System Engineering in L.D. Converter Steelmaking

摘要

The paper discusses the system optimization of L.D. converter steelmaking process. From the process practice of the plant, the method of system engineering has been used to analyze various objects and parameters, therefore a mathematical model of multiple-objective optimization is found. From data processing, the control parameter that decides mini-amount of slag forming material in steelmaking, which authors called the slag forming coefficient a, and the slag calculation formula are searched. The practice over two years shows, by scientific management and optimal operation based on mathematical optimization, the plant has obtained better technical and economical effects.
