Abstract
A ladle that can melt and freeze castable metal in a specific manner so that high quality liquid metal and metal alloys may be produced with minimum oxide and hydrogen content. Upon introduction of a quantity of molten metal into the ladle, staged heating and cooling of the molten metal promotes the liberation of previously-dissolved gases from the castable metal, resulting in significant decreases in as-cast porosity.
