Abstract

The effect of superheating and substrate morphology on heat exchange at the melt-solid interface was studied. An experimental device was set up to yield a unidirectional heat flow from the Sn-Pb bath to the lubricated steel substrate and the heat transfer resistance was evaluated from the thickness of the solidified material at a fixed time. A higher solidification efficiency was obtained with moderate superheating, and also with a proper choice of surface topography and lubricant.
