Disclosed is a method for converting box form dimensionally stable anodes to the more useful and energy-saving expandable type. In one embodiment, anode box plates are cut off the anode riser at the closest point thereto. Expander springs are then attached to the anode riser and the anode box plates which have been cut into quarter panels, sized and spliced together to form new anode plates are rewelded to the expander springs. Alternatively, the method comprises the steps of cutting away only the end portions of the box anode structure and bending remaining portions of the anode screens into a spring form similar to expander springs and attaching a new pair of anode plates or screens to adjacent pairs of these newly formed springs. The anodes may then be substituted in a diaphragm-type electrolytic cell for the production of alkali metal hydroxides and halogen and the energy savings associated with the use of expandable anodes may thereby be realized. |
