Abstract

Improvements in rotary retort ovens, for the thermochemical treatment of metals and alloys in gaseous media, characterized by the fixation of a spiral (5) inside the retort (2) and in its walls and by the installation of conduits admission (11) and evacuation (8) of the gaseous flow inside the retort (2), separating the spiral inside the retort in treated material (10) from the deposition that accumulates inside the retort (2), thus allowing the substance released from the gaseous flow to be uniformly deposited on all surfaces of the treated material, while the installation of the intake (11) and evacuation (8) conduits of the gaseous flow in the interior of the retort (2) allows to carry out the treatment operation only in the part of the furnace in which the thermal conditions favor the detachment of the gaseous flow of the substance composed of well-defined chemical composition.
