Development and Prospect of Prediction Model Technology of End-point of Converter
As a complex part of the traditional steelmaking process,most of the intelligent control models of converter are developed by foreign countries,and often return to artificial control because the model is not suitable for plant.Independent development of steel making models in line with the situation of iron and steel industry,the development trend and the demand of intelligent iron and steel industry.The development and its applications of converter model at home and abroad in recent years are introduced,including the modeling ideas,characteristics of BP empirical statistical model.The modeling ideas,characteristics of BP empirical statistical model and its application are reviewed,the modeling process of mechanism models are clarified,and the main difficulties and simplification methods of thermodynamics,dynamics and heat transfer model in the modeling process of mechanism model are analyzed.The modeling,simplified mode and calculation results of the SimuSage and CONSIM which are two existing commercial software models of converter are introduced.The developing trend and prospect of Chinese convert-er steelmaking model are foreclosed.The model development of converter should be pay more attention in the study of thermodynamic mecha-nism,multiphase flow mechanism,implementation monitoring and development,and the intelligent model of converter should be developt in-dependently.
