PURPOSE: An acid solution supply system for reducing scales is provided to prevent the scales by minimizing the changing of flow of acid solution. CONSTITUTION: An acid solution supply system for reducing scales comprises an acid solution tank(102), a connection pipe(103), a pump(104), and an air feeder(105). The acid solution is saved in the acid solution tank. The connection pipe connects the pickling tank and acid solution tank. The acid solution moves through the connection pipe. The pump transfers the acid solution saved in the acid solution tank to the pickling tank. The air feeder supplies the 0.1~10 weight% air about the volume of the acid solution moving to the connection pipe.
