meint salt bath heat treatment = Salzbad-Wärmebehandlung. Das molten wird nicht erwähnt, weil logisch. Vielfach wird auch einfach Salzbadhärten oder Vergüten im Salzbad verwendet.
Wenn Andrea uns jetzt noch den Zusatz verrät, könnte man vielleicht noch genauer werden und von Salzbadnitrieren, bzw Salzbadnitrocarburieren sprechen.
es ist vielleicht doch das Heizbad. Sorry, ich sollte nicht versuchen zu helfen, wenn ich müde bin. Ich versuch's jetzt wieder gutzumachen ;): Das hier belegt deinen Vorschlag: http://tinyurl.com/yfyeghk
Und hier noch weitere Quellen:

Mein Vorschlag: Salzschmelze als Wärmeträger in Heizbädern.
Gute Nacht :).
Ich glaube, es geht um Wärmebäder. Salzschmelzen werden dort zum Abschrecken/Abkühlen eingesetzt. Ich kann das jetzt leider nicht vollwertig belegen, weil ich echt müde bin :), aber das hier könnte dir schon mal weiterhelfen: http://tinyurl.com/yzav6uk

Additiv für Wärmebehandlung im Salzschmelzbad
Explanation: alternativ:
Zusatzstoff für Wärmebehandlung im Salzschmelz(e)bad
Automatic preheat. Upon immersion into molten salt, a frozen salt cocoon forms around the part. Layer thickness and the time required to melt it depend upon size and shape of the part, bath operating temperature and salt melting point. As a result, the work is subjected to an automatic preheat which prevents excessive heat shock and distortion damage of cracking. Furthermore, heat is transferred to the work over its entire surface uniformly. One side will not heat faster than the other. As the part gradually heats to the salt’s melting point, the cocoon melts leaving only the molten salt contacting the work. It is impossible for the work to be higher or lower than the bath’s temperature control.

The furnace has a ceramic or metal container filled with molten salt. The work can be immersed for either heating or cooling. The bath’s composition consists of one or more salts, nitrates, chlorides, carbonates, cyanides, caustics, or additives in small amounts. The additives can be sulphates, fluorides, etc. Heat is transferred between work and molten salt by conduction. The salt lends itself to either heating or cooling within a 300o to 2400o range, as required. Compatible salt mixtures are selected with proper operating ranges and often are formulated to meet specific temp-range requirements.
Operating principle
The electrode furnace generates direct heat in salt by using its resistance to current passage. Salts, while insulators in the solid state, are excellent high-resistance conductors in the molten state. Potential is applied to the molten salt by use of heavy electrode bars. These are connected to the secondary of special multiple voltage air cooled transformers. Electrodes are located in a recessed area of the bath and cause salt circulation by electromagnetic forces when energized. A strong magnetic field is created between electrodes when located close together.
Using Maxwell’s Law, this field will cause salt particles between electrodes to move downward in a whirlpool fashion. This electrodynamic circulation assures absolute temperature uniformity through the bath and eliminates danger of undesirable differentials.

Ajax Type H Furnace has a metal pot with electrodes entering from the top. This type furnace is preferred for cyanide hardening, carburizing, descaling, desanding, and cleaning.
Design features Furnace size and shape can be almost anything desired. One design uses a metal pot for temperatures up to 1750°. With this arrangement, electrodes must enter from the top and are usually located along the back wall free of the work area, see Fig. 2. All external walls are heavily insulated and radiation losses from surfaces are minimized by a suitable cover. The metal pot in this type furnace is used whenever salts contain appreciable amounts of cyanides, carbonates, and caustic soda, or for low temperature applications using nitrates and nitrites. http://www.p2pays.org/ref\07/06612.pdf

Es werden ein neues Verfahren und eine neue Vorrichtung zum Entfernen von Schlamm aus einer Salzschmelzbad-Flüssigkeit beschrieben, welche in einem Verfahren zum Einsatzhärten von metallischen Komponenten auf Eisenbasis verwendet wird.
Um den in diese heiße Salzschmelzbad-Flüssigkeit (14) zunächst gemischten Schlamm wieder aus dieser zu entfernen, wird die Salzschmelzbad-Flüssigkeit (14) durch erste und zweite Schlammauffangbehälter (62, 64) hindurchgeleitet, welche einzeln oder in Kombination verwendet werden können. http://www.patent-de.com/19940511/DE4337374A1.html
