Abstract

Beyond metallurgical aspects to yield clean steels, purging plugs in the ladle and beams in the tundish play a key role in generating bubble curtains to maximize the nonmetallic inclusion removal in a short time. However, technical challenges might be noted on how to control the bubble size through the design of the purging device and how to predict the kinetics of induced flotation for each bubble plume. Therefore, this work investigated two bubble size distributions and their effect on the kinetics of particle removal in a water model, providing insights into the design of purging devices for clean steelmaking.
