Water Model Experiments on Mechanical Agitation for Hot Metal Pretreatment Process

抄録

We propose two kinds of mechanical agitation methods to replace the conventional centric agitation method: offset agitation and centric agitation with an immersion cylinder. Particle Image Velocimetry (PIV) measurements are carried out to investigate the flow patterns in the bath agitated by these methods with an impeller often used in hot metal pretreatment processes. Low-density particles are most widely dispersed into the bath by centric agitation with an immersion cylinder.
