ANODE PLATE CORRECTIVE DEVICE FOR ELECTROLYSIS

摘要

PROBLEM TO BE SOLVED: To improve electrolysis efficiency by correcting an anode plate for higher flatness by projecting the contact part height of projection receiving parts among plural receiving parts in contact with the anode plate from the contact part height of holding parts facing pressing parts. SOLUTION: The plural receiving parts 21 to 25 which are implanted in a platen 40 and the plural pressing parts 10 which are advanced and retreated by means of driving mechanisms are pressed from the front and rear surfaces to the anode plate 1 for electrolysis to straighten the warpage generated at the time of casting. The positions of the contact parts 22a to be pressed to the anode plate 1 at the front ends of the projection receiving parts 22 which do not face the pressing parts 10 of the central parts of this anode plate straightening device for electrolysis are projected from the positions of the contact parts 21a at the front ends of the plural receiving parts 21 for holding in the peripheral parts facing the pressing parts 10 by the difference of aboutΔh=0.5 to 5mm. As a result, the anode plate 1 warping to recess upward is pressed until the plate recesses downward and, thereafter, the pressing is released and the anode plate is straightened to a nearly plane state by spring back. The flashes 1c at the peripheral edges are received by slope receiving parts 23, by which the curving of these flashes is prevented.
