Abstract
A system for applying tension to a component for use in molten metal processing. Preferably, the component includes an outer core and at least one tension rod positioned partially within the outer core. The component is preferably elongated, such as a support post or an impeller shaft. The tension rod applies compression to the outer cover, which makes the outer cover more resistant to breakage if it strikes, or is stricken by, an object.
