Abstract

L'INVENTION CONCERNE UN PROCEDE DE RECUPERATION DE SELS, A PARTIR D'UNE SOLUTION LIQUIDE DE RINCAGE UTILISEE POUR RINCER LES FONDANTS SALINS QUI RESTENT SUR DES PIECES QUE L'ON VIENT DE REUNIR PAR BRASAGE OU SOUDURE. DANS LE PROCEDE DE L'INVENTION, LES FONDANTS SOLUBLES SONT DISSOUS DANS LA SOLUTION DE RINCAGE TANDIS QUE LES AUTRES SELS INSOLUBLES Y SONT DISPERSES. ON RECUEILLE LA SOLUTION DE LIQUIDE DE RINCAGE, ON ENLEVE LES MATIERES SOLIDES NON DISSOUTES DE LA SOLUTION, ON CONCENTRE LA SOLUTION RESULTANTE PAR ELIMINATION DU LIQUIDE POUR FORMER UNE BOUILLIE; ON SOUMET LA BOUILLIE A UNE OPERATION DE SECHAGE POUR ELIMINER LE RESTE DU LIQUIDE ET ON RECUEILLE LE RESIDU. DE PREFERENCE, ON ANALYSE LE RESIDU ET ON Y AJOUTE SUFFISAMMENT DE SELS METALLIQUES POUR REDONNER AU RESIDU UNE COMPOSITION DESIREE DE FONDANT SALIN QUE L'ON PEUT ALORS REUTILISER.THE INVENTION CONCERNS A PROCESS FOR RECOVERING SALTS, FROM A LIQUID RINSING SOLUTION USED TO RINSE THE SALT FLUX WHICH REMAINS ON PARTS WHICH HAS JUST BEEN JOINED BY BRAZING OR WELDING. IN THE PROCESS OF THE INVENTION, SOLUBLE FLUX IS DISSOLVED IN THE RINSE SOLUTION WHILE OTHER INSOLUBLE SALTS ARE DISPERSED THEREIN. THE RINSING LIQUID SOLUTION IS COLLECTED, UNDISSOLVED SOLID MATERIALS ARE REMOVED FROM THE SOLUTION, THE RESULTING SOLUTION IS CONCENTRATED BY ELIMINATION OF THE LIQUID TO FORM A SLURRY; THE BOIL IS SUBJECTED TO A DRYING OPERATION TO REMOVE THE REMAINING LIQUID AND THE RESIDUE IS COLLECTED. PREFERABLY, THE RESIDUE IS ANALYZED AND SUFFICIENT METAL SALTS ARE ADDED TO THE RESIDUE TO GIVE THE RESIDUE A DESIRED SALT BASE COMPOSITION THAT WE CAN THEN REUSE.
