“…These streak lines are similar to the main stream lines reported in the previous paper. 6) The streak lines of top dross model particles for d pR ¼ 40 mm and 100 mm were approximately the same as those shown in Fig. 3.…”

“…The origin of the Cartesian coordinate system (x,y,z) was placed at one of the corners of the vessel. The flow field in the bath was divided into three regions as mentioned in the previous paper; 6) the entry region, the exit region, and the region enclosed with the belt. The belt velocity, v sM , was set at 1.5 m/s.…”

“…Unfortunately, information on the motions of the dross is very limited, [2][3][4][5] as mentioned in a previous paper. 6) Fundamental fluid flow phenomena in a real hot dip plating bath and the effects of the strip velocity on the dynamic behavior of the two types of dross have so far been investigated using a one-fifth and one-tenth scale cold model. 6,7) Some typical streak lines of model particles for the two types of dross were nearly the same as the main stream lines in the bath.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] There are two types of dross; top dross and bottom dross. The adhesions of these dross to the strip lower the quality of the hot dip plating sheets significantly, and accordingly, a variety of methods have been proposed to remove the dross out of the bath.…”

The motions of top and bottom dross with different diameters in hot dip plating baths were investigated using a transparent cold model vessel with a reduced scale of one-tenth. Polystyrene particles of the same density and diameter were used as models both for the top and bottom dross, and NaCl aqueous solutions with different densities were used as models for the plating melts. The typical streak lines of the top and bottom dross model particles were nearly the same as the main stream lines in the model bath regardless of the dross diameter. The top and bottom dross model particles were enriched in the region enclosed with the belt. Some of the model particles were trapped in the clearances between the sink roll and the belt. As the dross diameter became large, the number of top dross model particles floating on the bath surface increased and that of bottom dross model particles staying on the bottom wall increased.
