Abstract

This second part of a two-part article describes the application of the physical model and particle image velocimetry (PIV) system, treated in Part I, to studying the flows in the pool at the top of the casters used for semicontinuous casting of aluminum. The effects of various designs of “bags” that are used in the industry to modify the flow were determined, as were the effects of blocking the outflow “windows” of the bag and the effects of varying the submergence of the nozzle delivering metal into the bag. The flows were found to be strongly dependent on bag design; for example, on the length of the bag and the presence of windows in the bottom of the bag. Flows in the vicinity of the (simulated) solidification front were greatly changed by such apparently small changes in design as lengthening the bag by 50 mm. A qualitative explanation is offered for some of these effects, and the article ends with a discussion of what might be the best flow from the viewpoint of caster operability or ingot structure.
