Numerical Simulation of Multiphase Flow in Steelmaking Process

Abstract

In steel industry, multiphase flows are observed in many processes. It is important to understand an internal state to optimize the process. However, it is difficult to measure the internal state due to high temperature and high pressure in the furnace. Therefore, it is useful to estimate these phenomena by numerical simulation. In this report, the following three contents are mainly investigated, (1) Mechanical stirring in a KR process, (2) Supersonic jets in a converter, (3) Inclusion behavior in a continuous casting. Moreover, desirable analytical methods for the converters, which will be made practical in the near future are described.
