Optimization of Continuous Casting Using Simulation

This paper describes the development and use of an integrated system of metamodels and simulation experiments for managing quality in a continuous casting system. A systematic procedure was developed to satisfy the necessary process conditions connected to one or more process parameters. The values of these parameters are to be determined such that all the process conditions are satisfied simultaneously to ensure that the product will have the desired quality. This procedure utilizes a set of metamodels, simulation experiments, and an index called the “undesirability index” for quality, which establishes a functional relationship between the input variables or process parameters and the quality criteria. This system, when applied to the data pertaining to a case, demonstrated that the methodology developed could be used to effectively manage product quality.
