Abstract:The RH is one of the most important technologies in refining process. In the current study,a three-dimensional mathematical model for simulating the molten steel flow based on the parameters of 180 t RH has been established.Through application process test and numerical simulation method, the factors of inclusion distribution and inclusion removal were discussed. The experimental result shows that the inclusion removal rate is the greatest in the first 300 s,but most of the inclusions can not be removed in 850 s of RH reining. Through the numerical simulation, the removal behavior of the inclusions at 60 μm,40 μm, and 20 μm in RH was analyzed. The difference of the inclusion mass percent comparing the methods of numerical simulation and metallographic experiment is 15.8%. The numerical simulation method can be employed to predict the critical technological parameters during RH refining process.
