Salt Bath Furnace is engineered for heat-treatment of
any kind of metal in bright hardening & quenching, annealing,
carburizing, preheating, etc. The furnace is heated by electricity, oil
or gas. Salt bath furnace can be supplied as single "one off"
units or a comprehensive processing line which can be fully enclosed
with all necessary fume extraction and mechanical handling facilities.
How It Works?
Salt Bath Furnace system is utilized for service in a variety of
ferrous and non-ferrous thermal processing in either air cooled or water
cooled electrode and transformer designs. The electrode placement which
is submerged gives more uniform bath temperatures and salt movement by
natural convection currents. Cooler salts fall to the electrode area for
reheating whereas heated salts rise in the bath.

Buying Tips
In procuring automated salt bath furnace special attention should
be given so operator safety standards and local environmental
requirements are met. Moreover the insulation system, overheat
protection, heating element used, and the temperature distribution
should also be kept in mind before going for salt bath furnace.

- Robust construction helps in reliable production
- Low energy consumption
- Due to high quality thermal insulation operation cost is low.
- Heating elements that are used are are wounded on ceramic tubes.
- Heat is generated from all the four sides due to which uniform
heating takes place.
