The use of simulation to validate a new objective of steelmaking production

This paper discusses the application of Discrete Event Simulation (DES) for modeling the process of steelmaking continuous casting industry (SCC). The model was developed to validate the increase of steel production to 40%. It was used also to detect possible bottlenecks for the complex system which is characterized by various production rhythms, complexe crane movements, etc. A simulation model from blast furnaces, to continuous casting continues was developed and analyzed with the similator Witness. The results of this case study show that we can reach our objective by increasing the steel production to 3.5 millions tons, and detect, that the bottleneck of the system is Moved from the continuous casting (in the old configuration) towards the converters (in the new configuration).
