Application of expert systems to automate basic oxygen steelmaking operations
Project ID: 7210-CB/808Funded under: ECSC-STEELRES 7C
In recent years, many BOS plants have fitted additional equipment to improve end point control and reduce operating costs. Clearly such equipment must be maintained to a high level of operating efficiency and the metallurgical performance monitored to avoid any deterioration in product quality. This necessitates the capture and analysis of large quantities of data on computer systems. To achieve continuous surveillance and to diagnose problems as they occur, the systematic analysis which a qualified expert would apply has to be converted to a computer-based system. The aim of this research was to develop an automated system to diagnose problems and warn of potential failure, employing an expert systems approach. The main elements in the development programme were: - to analyse the variability in metallurgical performance and advise on the necessary corrections to achieve optimum performance; - to identify the engineering components critical to the reliability of the plant; - to determine the optimum maintenance requirements for each component, and - to evaluate the benefits of an expert systems approach. It is concluded that the expert systems approach is valuable in structuring the development of the final product. As the reasoning is clear and relatively easy to modify, it will be possible to apply the same schemes to other BOS plants.
