Abstract

Cold model experiments are carried out to determine the number, size, and surface area of slag droplets generated at a slag-metal interface in a cylindrical bath agitated by bottom gas injection. Acrylic monomer is used to represent slag, and water containing salt and gelatin is chosen to represent metal. Since the slag droplets become solid particles after a while due to polymerization, the quantities mentioned above are readily determined by taking them out of the bath and measuring their diameters with screens. As the average power input per unit mass, ε, and the density of the metal increased, the total number of slag droplets, S_p,t, was in proportion to ε, whereas the Sauter mean diameter, d_p32, was inversely proportional to ε. Empirical equations were derived for S_p,t and d_p32. The minimum diameter of slag droplets almost agreed with the diameter of the Kolmogorov micro scale of turbulence.
