Elimination of Expensive Alloy Electrodes
The Upton submerged graphite electrode design offers distinct costs savings in comparison with immersed type alloy electrodes. Graphite electrodes and transformers can be supplied as either air or water cooled.
Maximum Work Space with Minimum Bath Area
Through the unique submerged graphite electrode placement design, the electrodes do not occupy any portion of the bath. Only the active face comes in contact with the bath. This single exposed electrode surface minimizes bath size and increases electrode life over immersed electrode designs, and eliminates air/salt interface attack.
Convection Circulation Currents
The Upton submerged graphite electrode placement gives more uniform bath temperatures and salt movement by natural convection currents. Heated salts rise in the bath while cooler salts fall to the electrode area for reheating.
Engineered Triple Ceramic Refractory Wall Construction
The Upton triple refractory wall construction is designed so that the temperature gradient through the wall will cause any salt penetration through the hardbrick liner to solidify within the intermediate castable refractory materials. This refractory construction design limits initial salt absorption into the walls from 5 to 8 percent of bath volume, as opposed to 140 to 150 percent absorption experienced by some furnace designs using dual refractory wall construction with steel outer shell designs.
This engineered triple wall construction allows for the furnace to become a monolithic structure, sealing the refractories and minimizing outer wall distortion.
No Downtime with Renewable Graphite Electrodes
This unique electrode design allows for the addition of a graphite extension to the electrode proper as they become consumed during operation of the furnace. Replacement graphite electrode extensions are simply added by means of a connecting pin threaded into the rear of the electrode in service.
Graphite Electrode Advancement Mechanism
Upton submerged graphite electrode furnaces include pusher mechanism which allow for electrode advancement through the wall of the furnace. This allows for periodic feed of the electrode into the bath as it becomes consumed during operation.
Upton Submerged Graphite Electrode Salt Bath Furnace Applications
Upton submerged graphite electrode salt bath furnaces are ideally suited for aluminum dip brazing operations.
Custom Designed and Engineered
Our in-house engineering and manufacturing allows Upton to custom design furnaces and systems to a customers process and specification requirements, rather than attempting to provide to you standard pre-design equipment, as some of our competitors would attempt to do. Follow-up technical services are available for all Upton thermal process systems.
Our Engineered Thermal Solutions will allow for flexibility in your manufacturing productivity.
