Abstract

Water-cooling plays a major role in extracting heat from both the mold and solidifying metal during the continuous casting of steel and aluminum alloys and is characterized by complex boiling phenomena. Heat extraction rates during water-cooling, which have strong dependence on the metal surface temperature, can rapidly change with time as the strand cools down. Consequently, uncontrolled cooling may cause fluctuations in the temperature gradients inside the solidifying shell and generate tensile thermal stresses at the solidification front that can ultimately lead to the appearance of hot tears/cracks in the final product. This paper compares and contrasts the water-cooling techniques used for casting steel and aluminum and discusses their implications in terms of final product quality based on fundamental studies and predictive mathematical models. Finally, optimal practices for the control of cooling in casting processes for both steel and aluminum alloys are evaluated.
