DISTORTION CORRECTING APPARATUS AND DISTORTION CORRECTING METHOD OF PERMANENT CATHODE

摘要

<P>PROBLEM TO BE SOLVED: To provide a distortion correcting apparatus capable of sufficiently correcting the distortion of a permanent cathode occurring by repeatedly use in the non-metal electrorefining and electrowinning of a non-metal without degrading the smoothness of a cathode surface. Ž<P>SOLUTION: The distortion correcting apparatus for correcting the permanent cathode 1 includes a suspending means such as a hoist crane 2 for suspending the permanent cathode 1, a pushing means such as a hydraulic cylinder 3 for applying static load from the projected part side of the distortion to vertically push into the cathode surface of the permanent cathode 1 in a suspended state and a receiving means such as a rod like member 4 for receiving the permanent cathode 1 at least two position from the back side of the cathode surface on which the static load is applied. At least one of the permanent cathode 1 and the pushing means is movable in the vertical and lateral direction to the cathode surface. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
