Abstract EN
In this paper, factors influencing the inclusion removal in high-manganese and high-aluminum steel in RH refining process were studied by numerical simulations, production practice, and metallographic experiments.
A mathematical model for inclusion removal was established, and the phenomenon of inclusions mixing in RH up-leg region was verified due to fluid circulation.
Removal efficiency of RH circulation time 120 s is much better than 600 s, and it was the lowest efficiency after 600 s.
After 600 s circulation time, it shall not apply in production practice.
The mass concentration of inclusions in practical steel was 11.64% probability error than values obtained by numerical simulation, because the numerical simulation did not consider the problem of inclusions adsorbing to the walls of refractory materials and corrosion of refractories.
This work lays the foundation for the optimization and upgrading of process technology and establishes big data for full automation of RH out of furnace refining.
