Stirring generated by low gas flowrates helps improving steel quality and minimize oxidation. The soft bubbling phenomenon has been studied using a combination of multiple microphones and image sensors, in both physical modeling and industrial trials. In the cold model, stirring was monitored accurately under a range of conditions including closed-eye situations. In addition, ladle eye sizes measured at thicker oil heights indicated different trends than previous studies. Overall, the study suggested that a combined acoustic-optical approach will provide robust information of ladle eye dynamics at low gas flowrates compared to individual sensors in an industrial environment.
