Abstract

Un dispositif de traitement thermique de pièces métalliques comprend un four continu (1) pour chauffer des pièces métalliques (100) et un bain fluidisé (3) de particules solides pour tremper les pièces métalliques (100) chauffées. Le four (1) comprend un laboratoire (11) destiné à être traversé par les pièces métalliques (100) à traiter et un canal de chute (12) dans lequel tombent les pièces métalliques (100) après avoir traversé le laboratoire (11). Le bain fluidisé (3) est disposé directement dans le canal de chute (12). Un dispositif de fluidisation (4) servant à injecter du gaz de fluidisation dans le canal de chute (12) est disposé sous le canal de chute (12).

A device for heat treatment of metal parts comprises a continuous oven (1) for heating metal parts (100) and a fluidized bath (3) of solid particles for quenching the metal parts (100). The oven (1) comprises a laboratory (11) intended to be traversed by the metal parts (100) to be treated and a chute (12) into which the metal parts (100) fall after passing through the laboratory (11). The fluidized bath (3) is placed directly in the chute (12). A fluidization device (4) for injecting fluidization gas into the drop channel (12) is arranged under the drop channel (12).
