Abstract

Procédé dams lequel la solution de décapage est pulvérisée sur la pièce métallique dans une atmosphère confinée avec un apport d'oxygène par introduction dans l'enceinte de pulvérisation d'un gaz contenant de l'oxygène, la solution de décapage étant recyclée dan un circuit fermé de solution de décapage. Dispositif de décapage par pulvérisation de surfaces métalliques qui comprend une enceinte de pulvérisation (1) munie d'une cuve réceptrice (2), des moyens de pulvérisation (6) d'une solution de décapage (S) dans ladite enceinte, des moyens de recirculation (11) de ladite solution entre ladite cuve (2) et lesdits moyens de pulvérisation (6), et des moyens de ventilation de ladite enceinte (8, 9) par un gaz (G) contenant de l'oxygène, et ' . " des moyens de maintien en température ( 13) de ladite solution et des moyens de contrôle. Amélioration de la productivité de lignes de décapage de pièces en acier inoxydable ou allié en économisant les réactifs.
