Abstract
Roll forming is used for re-shaping an iridium crucible. The crucible is placed on a platen. The platen rotates the crucible while heat is applied by a plurality of torches. A plurality of rollers press on the rotating, heated crucible to re-shape. The roll forming allows for a greater number of repetitions of the re-shaping, increasing the number of uses per expensive re-fabrication of the crucible. The roll forming may provide more exact re-shaping.
