Abstract

During casting of aluminum ingot by a new process utilizing level pouring, variations in cooling rate within the surface band occur as a result of the discontinuous nature of metal flow. Associated segregation contributes to a marked cyclic pattern of the macrostructure in that region. The kinetics of metal flow into the surface zone are explained graphically using a sequence of macrographs. The proposed mechanism is also supported by results of thermal measurements and Electron Microprobe analyses.
