摘要： Computer-implemented processes for making refractory metal pots, including: cutting an a refractory metal ingot into a first workpiece; subjecting the first workpiece to multiple upset forgings, annealings in a vacuum or inert gas to a temperature sufficiently high to cause at least partial recrystallization, forging-backs, and rollings to form a plate; wherein the forged, annealed workpiece undergoes a reduction in thickness after at least one rolling pass and is turned between at least one pass, to form the plate; and deep drawing the plate to form a pot; wherein dimensions of at least one workpiece or plate suitable for processing into a pot are pre-determined with a computer-implemented finite element modeling assessment method.

摘要： A forging press includes a die set having a stationary die, a movable die in facing-but-spaced-apart relation to the stationary die along a press axis and defining a workpiece volume therebetween, and an exterior constraint extending circumferentially around the workpiece volume. The movable die has a base level region lying generally in a workpiece plane perpendicular to the press axis, and three rotationally symmetric segments raised above the base level region. Each of the segments forms an angular segment of a disk having an included segment angle and that is angularly separated from the other segments. A press mechanism includes a axial drive operable to move the movable die in a direction parallel to the press axis, and an indexing drive operable to rotate the movable die about the press axis by an indexing rotational angle. In operation, the axial drive performs a press stroke and retracts, the indexing drive rotates the movable die by the indexing rotational angle of less than the included segment angle, and the axial drive performs another press stroke. By repeating these steps, the entire workpiece is forged incrementally.
