【 摘 要 】

Modelling complex behaviour of steelmaking processes, affected by the dynamic environment and subjective actions of human interaction is a challenging task. Using modelling techniques, based on first principle, to describe the dynamics of the process, comes with inherent limitations when trying to fit experience into equations. The UK based branch of TataSteel RD&T has successfully developed an application of Case Based Reasoning technology for predictive modelling in the steel industry. The model predicts final chemical composition and advises on safe tapping operations. This paper describes the approach and structure of the model and share experience gained during model development and exploitation. The model evaluation is based on 10 years of continuous monitoring and shows consistent accuracy of 80%-90% under changing manufacturing conditions and material quality. The benefits of using recent experience for effective tracking of changes in manufacturing practices, material quality and qualitative fluctuations are discussed.
