ABSTRACT:
A process for the production of columnlarly solidified metallic bodies by melting metal and then solidifying said metal in a crucible, wherein the dissipation of heat is greater at the upper or lower end of the crucible than at the sides, which comprises supplying heat to the verticals sides through a heating element having a plurality of individually controlled heating sections in such a quantity that a melt of the metal is formed and then establishing directional solidification by establishing a temperature gradient by varying the heat output among the heating sections of the heating element by switching.
