ABSTRACT:
A method for the removal of carbonizable, adherent coatings from the surfaces of metal parts, in which the metal parts are baked or pyrolyzed in the course of the method. The metal parts are brought to the carbonizing temperature in a substantially closed retort. Without leaving the retort, the adherent, carbonized coating is blasted off by means of heated blasting medium as the carbonization proceeds or after it ends. The heating of the metal parts is performed in a fluidized bed within the retort. The medium of the fluidized bed is simultaneously the blasting medium.
