The invention relates to a continuous pickling and wiredrawing process of a brass wire, which is characterized in that: after being drawn out of a wire releasing disc, a brass wire blank is subjected to continuous processes of pickling, neutralizing, brushing, cleaning and wiredrawing. A continuous producing mode is used for connecting the pickling process and the drawing process of the brass wire together, namely that after an annealed brass wire blank is arranged on a wire releasing frame by one end of a production line, a finished product of the fine-drawn brass wire can be generated from the other end, therefore, the continuous producing mode has few processing and flowing processes and stops scrapes and compression injuries in the flowing process; pickled products are wiredrawn in a shorter period to ensure better brightness and consistency of product appearance and obviously increase the surface quality of the finished product of the brass wire; the processing process has high automation degree, reduces labor intensity of staffs and increases production efficiency; when the brass wire is in the pickling process, an oxide layer on the surface of the brass wire only needs to be loosened; and therefore, when the brass wire is pickled, nitric acid does not need to be added, the usage amount of acid liquor is greatly reduced, and the production cost is reduced.
