Graphite Electrode Salt Bath Furnaces

Submerged Graphite Electrode Design

Graphite electrodes and transformers are available with air or water cooling.

Submerged Electrode Placement

Only the electrode faces touch the salt; the electrodes themselves take up none of the bath space, so the whole bath stays clear for work.

Convection Circulation Currents

Heated salt rises in the bath while cooler salt falls toward the electrode area for reheating.

Engineered Triple Ceramic Refractory Wall Construction

The triple refractory wall is designed so the temperature gradient through the wall causes salt penetrating the hardbrick liner to solidify within the intermediate castable layers. This construction is designed to limit initial salt absorption into the walls.

Replaceable Graphite Extensions

As the graphite electrode is consumed, extensions connect to its rear by a threaded connecting pin.

Graphite Electrode Advancement Mechanism

A pusher mechanism advances the electrode through the furnace wall and feeds it into the bath as it is consumed.
