Spout formation in a gas-stirred ladle: Experimental results

Model experiments simulating the spout formation in a gas-stirred ladle were performed with and without a slag-simulating phase (oil) above the bulk liquid (water). The height and width of the spout region were obtained by means of a digital video technique over a wide range of operating conditions. A dimensional analysis of the experimental data was employed to correlate the characteristic dimensions of the spout region to the operating …
