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.
Claims31
A support post comprising an elongated body having a longitudinal axis and a height, a first end configured to connect to a superstructure and a second end configured to connect to a pump base, wherein the second end comprises at least one reinforcement section configured to make the second end resistant to breakage.
The support post of claim 32 that has two air-relief grooves.
