Plan your equipment
Send the alloy, part dimensions, load arrangement and required cycle, and we’ll discuss whether a heated salt bath furnace or an automated system suits the work.
Salt bath furnaces
-
Automated Salt Bath Systems
Upton configures automated salt bath systems with PLC controls and material handling for multiple processes.
-
Externally Heated Salt Pot Furnaces
Externally heated salt pot furnaces with carbon-steel or stainless-steel liners, electric resistance heaters or Upton Hurricane gas burners, for intermittent service.
-
Internally Heated Salt Bath Furnaces
Internally heated salt bath furnaces for non-chloride salts, with carbon-steel or stainless-steel liners.
Externally or internally heated
Both are steel-lined salt bath furnaces. They differ in where the heat enters the salt: through the wall of a pot, or directly in the bath.
| Externally Heated Salt Pot Furnaces | Internally Heated Salt Bath Furnaces | |
|---|---|---|
| Heat enters | From outside the pot, through its wall | In the salt, from heat sources immersed in the bath |
| Electric | Electric resistance heaters | Immersion heaters for lower-temperature work; air- or water-cooled electrodes with transformers at elevated temperatures |
| Gas | Upton Hurricane tangential burners, designed to minimize flame impingement on the salt pot | Radiant tubes |
| Suited to | Intermittent service | Non-chloride salt applications |
| Liner | Carbon steel or stainless steel, selected for the operating conditions | |
