| Abstract Scope |
In the steelmaking process, molten slag is foamed through gas injection and gas generation reactions, and molten iron droplets get mixed and trapped in the slag. When the slag is disposed of, the droplet iron flows away along with the slag, resulting in iron losses. A settling velocity of iron droplets in the foaming slag is required to reduce the iron losses. The settling velocity is expected to be slower than in regular nonfoaming slag. However, it has yet to be quantitatively clarified. This study measured the settling velocities of particles through a foaming liquid of glycerin-water solution. A dimensionless correlation equation for particle settling velocity in the formed liquid was proposed by conducting a dimensional analysis of the experimental data. Using the obtained equation, we have predicted the settling velocity of iron particles in the foaming slag. |
