Modeling simulation and optimization study of the mode of “route with one open ladle from BF to BOF” in BF - BOF region based on WITNESS

The paper introduces the application of software Witness, and discusses the cumulative effect of ladle caused by waiting time and the methods of using the software Witness in the simulative interface mode of “route with one open ladle from BF to BOF” in BF -BOF region. The author studies the factors to “bottlenecks” phenomenon in the modeling simulation and the factors to cumulative effect by waiting time of the ladle. Based on the results of model simulation, the author not only points out the measures to resolve this problem, but also proposes the ways to alleviate the cumulative effect through improvements by setting the parameter on the modeling simulative system.
