A method of prolonging the life of a carbon anode ring furnace is disclosed wherein portions of the confronting refractory brick flue walls of the furnace which have partly collapsed can be readily straightened. The refractory bricks of the collapsed portion of a flue wall are urged back into the plane of the wall by interposing a hydraulic jack between the closely spaced flue walls and actuating the jack to apply opposing forces to the wall. The jack is positioned and actuated in a number of locations corresponding to a predetermined circular pattern about a deformation zone to successively reduce the deviation of the bricks of the deformation zone. A tie brick is thereafter inserted between the walls to maintain them in their normal spaced relation.
