A Note on the Determination of Mixing Times in Gas Stirred Ladle Systems.

Abstract: IntroductionThe study of mixing phenomena in gas stirred ladle systems has received considerable attention over the years. In a series of recent contributions,1~3) Krishnamurthy and coworkers have investigated mixing phenomena in gas stirred liquid baths and have proposed a modelbased on the concept of a "circulation time."I'4,5) Their modell) in its updated form2) was used to assess our experimental studies of mixing, which reported on 10cation effects of tracer addition and monitoring poipts on mixing times.… Show more

“…On the other hand, various authors conclude that not only the location of the sensors 22) affects the mixing time measurements but also the location of the tracer addition [23][24][25] is a variable that considerably affects the time required to reach a homogeneity degree of 95%. The discrepancies between authors have given rise to discussions and communications 26) between authors with reference to the relevance of the influence that a location of the addition of the tracer has on the experimental measurements of mixing time. The last, supports the pursued objective of the present research that is to elucidate the effect that the tracer addition location has on the measurement of mixing time on a ladle furnace, four cases of study were proposed.…”

“…Thus, physical modelling and mathematical simulation are necessary to better understand the formation and evolution mechanism of inclusions during the ladle mixing process. It was regretful that chemical composition of inclusions can hardly be well predicted in the previous investigations [28][29][30][31][32][33][34][35][36][37][38] due to complicated calculations and lack of thermodynamic data in the multicomponent system.…”
