Effect of Immersion Cylinder on the Dispersion of Low Density Particles by Mechanical Agitation

Water model experiments were carried out to promote the dispersion of fine particle into a molten steel bath agitated by an impeller. The dispersion was significantly promoted by immersing a circular cylinder at a radial position between the center of the bath and side wall of the vessel. This is because the liquid flow on the bath surface becomes asymmetrical with respect to the center line of the bath in the presence of the cylinder and, as a result, a large scale vortex is formed in the bath.
