Ceramic Salt Bath Furnaces

Maximum Work Space with Minimum Bath Area

Through the unique submerged 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, while eliminating air/salt interface corrosion attack.

Convection Circulation Currents

The Upton submerged 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 bath liner to solidify within the intermediate castable refractory materials. This engineered 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 shells.

This engineered triple wall construction allows for the furnace to become a monolithic structure, sealing the refractories and minimizing the potential of outer wall distortion or furnace leakage.

Electrode Placements Give Clear Working and Cleaning Area

The Upton submerged electrode design creates a clear bath volume free of any protruding obstructions, allowing for maximum working area while providing for ease of bath maintenance.

Upton Ceramic Salt Bath Furnace Designs

Upton Ceramic Salt Bath Furnaces can be employed for service in a variety of ferrous and non-ferrous thermal processing in either air cooled or water cooled electrode and transformer designs.

Thermal Process Applications

Upton salt bath furnaces are used for various high temperature ferrous and non-ferrous thermal processing applications such as neutral hardening, Austempering, Marquenching, tempering, case hardening, and dip brazing.

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.
