Abstract (en)
[origin: EP0728579A1] The steel scraper (1) has about 10% of its surface treated anodically to reduce the current consumption and heating. The treated area is characterised by pits or caps formed while an endless band passes through an electrolyte-filled gap between plate cathodes, and under an anode roller. The blade (2) is kept free from burrs or notches while the treated area is surrounded by a laminar flow of electrolyte. The DC voltage between the anode and cathodes is maintained at pref. 4 to 10 v, and the current is pref. between 100 and 200 A.
