Multi-Stationed Continuous Electro-Polishing System

Abstract

A multi-stationed continuous electro-polishing system includes an electrolysis tank, a driving mechanism, electrode plates and a power supply. The electrolysis tank is filled with electrolyzing liquid. The driving mechanism is placed in the electrolysis tank for driving a metal strip into and out of the electrolysis tank. Each of the electrode plates is placed at an adjustable gap from the metal strip in the electrolysis tank. The power supply includes a positive electrode connected to the metal strip and a negative electrode connected to all of the electrode plates.

1 . A multi-stationed continuous electro-polishing system including:
 an electrolysis tank  1  filled with electrolyzing liquid  11 ;   a driving mechanism  2  placed in the electrolysis tank  1  for driving a metal strip  3  into and out of the electrolysis tank  1 ;   electrode plates  4  each placed at an adjustable gap  41  from the metal strip  3  in the electrolysis tank  1 ; and   a power supply  5  includes a positive electrode  51  connected to the metal strip  3  and a negative electrode  52  connected to all of the electrode plates  4 .   
     
     
         2 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the electrolysis tank  1  includes nozzles  12  each placed between two adjacent ones of the electrode plates  4  in the electrolysis tank  1  for providing a jet to wash the metal strip  3  of bubbles that occur in the electro-polishing. 
     
     
         3 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the electrolyzing liquid is solution of acid selected from the group consisting of sulfuric acid, phosphoric acid, glycerol, nitric acid, hydrochloric acid, lactic acid, citric acid, chromic acid, phosphorous acid, and organic acid. 
     
     
         4 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the driving mechanism  2  includes:
 at least two small rollers  21  placed in the electrolysis tank  1  near two ends; 
 at least two large rollers  22  each placed in a respective one of the small rollers  21  in the electrolysis tank  1 ; and 
 at least two driving rollers  23  placed outside the electrolysis tank  1  near a respective one of the large rollers  22 . 
 
     
     
         5 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the metal strip  3  is 0.5 mm to 0.005 mm thick and hence flexible. 
     
     
         6 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the power supply  5  operates in a continuous manner. 
     
     
         7 . The multi-stationed continuous electro-polishing system according to  claim 1 , wherein the power supply  5  operates in an intermittent manner.
