Salt Bath Furnaces Overview
Automated Salt Bath Systems
Upton automated salt bath systems can be custom designed with integrated multiple process capability. Precleaning, heat treating, post cleaning and part- surface finishing can be incorporated into the single automated system eliminating the requirement of additional handling and processing equipment. Finished parts can be unloaded ready for packaging and shipment.
Ceramic Salt Bath Furnaces
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.
High Speed Salt Bath Furnaces
Upton salt bath furnaces offer the ultimate in temperature uniformity for minimized distortion and residual stresses, producing maximum physical properties without requiring a skilled operating technician.
Mar-Ausquenching Salt Bath Furnaces
The Upton Mar-Ausquench Furnace design combination of a internal quenching shroud and variable speed propeller type agitator provides vertical lamellar flow to the workload. Maximum quenching with minimal distortion is assured.
Internally Heated Salt Bath Furnaces
Upton manufactures internally heated, metallic inner lined salt bath furnaces designed for use with non-chloride based salt applications. These furnaces can be constructed from carbon or stainless steel materials as operating conditions warrant.
Externally Heated Salt Bath Furnaces
Upton manufactures externally heated, inner lined salt bath furnaces designed for various applications. These furnaces can be constructed with a carbon or stainless steel pot liner materials as operating conditions warrant.
Graphite Electrode Salt Bath Furnaces
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.

Salt Bath Cleaning & Stripping
Upton salt bath cleaning systems are provided in an arrangement with the molten salt bath, waste material dumping station and water washing and rinsing tanks combined within a single safety/ventilation enclosure. This system allows for operator control of the process from outside the unit and away from heat and residual fumes. Most systems are designed for use with existing material handling conveyors or monorail type hoists.
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 APPLICATIONS
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.
