Abstract
Fully dense long ingots are produced by the bottom pouring method and apparatus of the present invention. A solidification sequence is achieved which is conducive to eliminating solidification shrinkage and piping. The set-up of the bottom poured ingot molds facilitates a solidification sequence starting from the top and then down the ingot mold and then up the down pour pipe.
