Cold model experiment on entrapment of inclusions in steel by inert gas bubbles

Abstract

Cold model experiments have been carried out done on entrapment of inclusions in steel by inert gas bubbles. A water air system has been adopted and the teflon, polystyrene, polyethylene, polypropylene and polycarbonate particles were used in the experiments. The collision trapping rates of various particles with bubbles were measured, and the effects of water particle contact angle, the particle diameter, the bubble's diameter, the particle density, and the frequency of bubbles passing through a unit volume of water have been investigated.
