Abstract
Abstract The apparatus and method for effecting the restructuring of metals disclosed herein provides a container for holding molten metal in a controlled atmospheric or vacuum environment into which an open-ended shell mold is immersed so that the wall of the mold separates and confines molten metal intended to be formed from the surrounding molten mass. A chill means is placed in engagement with the confined molten metal at the top opening of the mold which begins solidification thereof at the molten metal interface. Means are provided for moving the chill means so that the solidified portion of the formed part is withdrawn from the mold as required. Planned withdrawal of the solidified portion creates a continuously new interface area which then progressively solidifies until the formed part is completed.

Claim 1
Independent Claim
239 words
Apparatus for restructuring metals for producing shaped forms by transforming metal in a fluid molten state to a solid state comprising: a container for holding a body of molten metal having an exposed surface level; means surrounding said container below said surface level for heating said container and said molten metal; a divider type mold having an internal cavity open at its opposite ends and disposed in said body of molten metal so that its uppermost opening is substantially adjacent said surface level and said lower most opening conducts molten metal into said cavity whereby molten metal within said cavity is separated from the surrounding molten metal mass except for the presence of said molten metal in said lowermost opening; a chill means including a chill bar disposed over said surface level in alignment with said uppermost mold opening and adapted to engage with said molten metal within said cavity at said surface level thereof; means for moving said chill bar into engagement with said molten metal within said cavity and for drawing said chill bar with said molten metal after solidification from said body of molten metal; said chill bar being of lower temperature than the temperature of said molten metal whereby solidification of said molten metal within said cavity occurs upon engagement therewith; and divider type mold composed of temperature sensitive material effective to break away from said solidified metal as it separates from said surface level.

Claim 3
Dependent Claim
52 words
The invention as defined in claim 1 including a bond established between said chill bar and said solidified metal so that said solidified metal is attached to said chill bar and further a heat sink is provided in addition to said chill bar for effecting solidification of said molten metal adjacent thereto.
Claim 4
Dependent Claim
17 words
The invention as defined in claim 1 including means releasably securing said mold to said chill bar.
Claim 5
Dependent Claim
205 words
Apparatus for restructuring material to produce a shaped form comprising: a body of molten source material having a surface level; a divider type mold having an open-ended internal cavity immersed in said molten source material body so as to separate a portion thereof which occupies said internal cavity and is divided from the mass of said molten source material body; cooling means supported above said surface level operable to selectively engage said separated portion approximately at said surface level; said cooling means being of lower temperature than said confined molten source material whereby said material at the interface of engagement with said cooling means will be characterized thereby having established therein a solidification front adapted to transform or convert the state of said molten separated portion to a solid form having the congruent shape of said internal cavity; means operably connected to said cooling means for moving said solid form away from said surface level at a pre-determined rate so that said solidification front progressively moves aLong the entire length of said separated portion of said molten source material; and said divider type mold is composed of temperature sensitive material effective to break away from said solidified metal as it separates from said surface level.
