Abstract
A vertically-elongated member, which is preferably a support post used in a molten metal pump, includes a ceramic tube and tensioning structures to add a compressive load to the tube along its longitudinal axis. This makes the tube less prone to breakage. Another vertically-elongated member, such as a support post, includes one or more reinforcement members to help alleviate breakage. A device, such as a pump, used in a molten metal bath includes one or more of such vertical members.
Claims26
A component for use in a molten metal pump, the component comprising:
- an outer core constructed of graphite or ceramic;
- a tension rod positioned partially inside the outer core, wherein the tension rod has a first end and a second end, and is configured to apply an axial compressive force to the outer core in order to make the outer core less susceptible to breakage;
- wherein the first end of the tension rod extends beyond the outer core and has an axially-compressive component positioned thereon, the axially-compressive component positioned against the outer core to place an axial-compressive force on the outer core.
