Salt bath furnace

Thermal treatment furnace where the molten salt is contained in a gas-, oil- or resistance-heated steel crucible. The castings to be treated (workpieces) are immersed in the salt bath.

Salt bath furnaces can also be used to lower high annealing temperatures to the (isothermal) temperature set in the hot bath, for example, in hot-bath hardening or austempering.
