Abstract:
An improved crucible for containing a body of molten metal and for adding heat to offset thermal losses during transportation, said crucible comprised of:(a) a bottom and sides joined together to contain said molten metal; (b) a liner comprised of a refractory substantially inert to said molten metal; (c) at least one pocket of a metal or metal alloy contained in said liner having a melting point above that of said molten metal; and (d) means for beating provided in said pocket of metal or metal alloy in said liner to heat said metal or metal alloy to a temperature above its melting point, said metal or metal alloy suited for transferring transformation heat to said body of molten metal during solidification, thereby maintaining said body of molten metal molten for an extended period.
