- •
The fluid flow and mixing behavior in the RH degasser without and with simultaneous bottom injection of gas (one porous plug, and three porous plugs, respectively) were investigated and compared based on a numerical method.
- •
The locations of plug were optimized to improve the mixing efficiency in the RH degasser.
- •
Industrial trials were preliminarily conducted to study the effect of bottom injection on decarburization rate during the RH degassing.
