| Abstract Scope |
There are many different metallurgical processes, like ladle and converter in the steelmaking as well as many processes in non-ferrous metallurgy, where gas is injected into a vessel. Typically, inert gases are used for homogenization and refining, but there are also oxidizing and reducing gas species used in some of the processes. In all cases small bubbles well distributed in the vessel are preferred to maximize the gas-metal-interface.
In this work different injector systems like open lance, 3-hole-nozzle, Laval-nozzle and impeller are compared concerning their degassing efficiency. Therefore, a cylindrical water model is filled with water. While degassing with pure nitrogen the oxygen concentration of the water is measured continuously.
The measurements show huge differences concerning the degassing rate as well as the residual oxygen content in the water for the different injectors. |
