Abstract
In direct cooling an ingot emerging from a mold, two sets 136 and 142 of liquid coolant streams are discharged onto the ingot from an annulus 62 circumposed about the lower end opening 72 of the mold. One set of streams, 136, is discharged downwardly at 22.5 degrees to the axis 12 of the mold, and the other, 142, is discharged downwardly at 45 degrees to the axis of the mold. The two sets are staggered to one another circumferentially of the mold, and because of the high angle of incidence of the 45 degree set to the axis of the mold, substantial portions of the 45 degree streams rebound from the surface of the ingot at their points 144 of impact with the ingot, and mushroom into corolla-like masses of air borne liquid coolant spray 146 lying crosswise the paths of the 22.5 degree streams, which in turn entrain the spray and impact the successive layers 138 of coolant therebelow with the spray. To aid in the entrainment, the respective streams are spaced apart from one another so closely that the respective pairs of adjacent corolla-like masses of spray actually shoot up "interaction fountains" 148 of spray directly in the paths of the 22.5 degree streams of coolant. The effect is …
