Abstract
Both the position and shape of the solidification front in molten metal passing continuously through the horizontal solidification chamber of a mold body are precisely controlled in the invention by establishing a cooling probe insertion pattern in which some of the probes are inserted into cooling bores in the mold body to greater distances than others. Specifically, establishment of a solidification front characterized by a liquid/solid isotherm that is substantially symmetrical across the chamber is achieved by progressively increasing the cooling probe insertion distance from the bottom to the top of the mold body. Premature, asymmetrical solidification on the bottom of the chamber is effectively minimized and reduces hot tears, fissures and other surface defects in the casting.
