Numerical simulation of fluid flow and alloy melting in RH process for electrical steels
文献摘要：
Based on the Eulerian-Lagrangian approach,a mathematical model was established to describe the gas-liquid flow behavior in the Ruhrstahl-Heraeus(RH)degasser.The momentum source and the turbulent kinetic energy source due to the motion of gas bubbles were considered for the liquid flow.The effect of the expansion of gas bubbles on the liquid velocity,recirculation rate,and mixing time was quantitatively evaluated.After the fluid flow reached the steady state,the melting and mixing processes of aluminum alloys in the RH degasser were also investigated.The results indicate that the expansion of gas bubbles has a significant influence on the recirculation rate and the mixing time in the RH process.Increasing the superheat of liquid steel and decreasing the initial diameter of alloy particles are beneficial to promote the melting and mixing of alloy particles.Due to the existence of solidified steel shells,the maximum diameter of the alloy particle is about 1.5 times its initial diameter.
