Abstract
An apparatus for processing a quantity of glass melt comprises a segmented tube including a first tube segment and a second tube segment. A second end portion of the first tube segment is joined to a first end portion of the second tube segment. In further examples, methods of fabricating a segmented torsion tube include joining together segmented torsion tubes at an integral solid-state joint.
Claims32
An apparatus for processing a quantity of glass melt comprising:
- a glass melt stirring chamber;
- a segmented torsion tube including a first tube segment comprising a seamless tube fabricated from a first material, a first end portion and a second end portion, the segmented torsion tube further including a second tube segment comprising a tube fabricated from a second material, a first end portion and a second end portion, wherein the second end portion of the first tube segment is joined to the first end portion of the second tube segment at a joint;
- at least one stirring blade mounted to the segmented torsion tube;
- and
- a motor configured to apply torque to the first tube segment.
