干磊, 何平. Study of Water Model on Mixing Characteristics of Flow Field in CAS Ladle with Deep Inserting Snorkel[J]. Special Steel, 2008, 29(1): 28-30.DOI:
The effect of inserting depth (0 - 20% depth of bath to surface) and diameter (0. 4 ~0. 7 of ladle bottom diameter) of snorkel on mixing time of bath has been studied by water model of 1/6 of 110 t CAS ladle. Results showed that with increasing depth and diameter of snorkel the circulated flow in snorkel increased and with deep inserting snorkel (20% depth of bath to surface) the flow field in ladle varied distinctly and the circulated flow in snorkel fbimed obviously. The experimental formula for expressing the effect of bottom gas amount Q and depth of inserting snorkel H on mixing time(T-T
