  • Method for producing a body from a material susceptible to thermal cracking and casting mold for executing the method
    Patent number: 5236033
    Abstract: Methods are known for producing a body from a material susceptible to thermal cracking, in particular from an alloy, by casting a melt of the material in a mold with thermally insulated side walls and a bottom of material with good thermal conducting properties and cooling the melt in the casting mold, where the solid-liquid interface forming as the border between the melt and the already solidified material essentially extends parallel to the bottom and, in the course of the solidification of the melt, moves from the bottom in the direction of the exposed surface of the melt.
