Title:
METHOD FOR MANUFACTURING AND DEVICE FOR MANUFACTURING ALUMINUM PRODUCT
Document Type and Number:
WIPO Patent Application WO/2015/011912
Kind Code:
A1
Abstract:
A method for manufacturing an aluminum product includes a spray step as a boehmite treatment step in which a processing solution is sprayed on a workpiece (22), which has been heated in a brazing step, to cool the same after the brazing step. The workpiece (22) has been heated after the brazing step. The processing solution is sprayed on the workpiece (22) in this heated state, and the surface of the workpiece (22) that is made to come into contact with water molecules can be modified to a corrosion resistant boehmite. In addition, the sprayed processing solution can be dried by the heat of the workpiece (22). Thus, the brazing step, surface treatment step, and drying step can be carried out consecutively.
