Abstract
A bottom block for use in direct chill (DC) casting that includes a flared base providing additional surface area for contact with coolant used in the DC casting process. The bottom block includes a first end that substantially fits within a DC mold while a second end has a larger cross-sectional area than the first end. A transition between the first end and the second end provides a surface for coolant to contact despite film boiling and air gaps between the ingot and the coolant.
