Title
(EN) WALKING BEAM FURNACE FOR CONTINUOUSLY DISCHARGING AND SHREDDING SCALE
(FR) FOUR À LONGERONS MOBILES PERMETTANT DE BROYER ET D'ÉVACUER EN CONTINUE LA CALAMINE
Abstract
(EN)
Walking beam furnace comprising movable (10C) and stationary andirons which are supported by movable (12Q) and stationary keels, respectively, and drive means designed to move a lifting frame (2) and a translation frame (3) according to a rectangular displacement cycle having two vertical positions and an intermediate vertical position according to which the movable andirons are at the same height as the stationary andirons, the furnace further comprising stationary and movable beams (LRM), the movable beams being arranged between the stationary beams and separated from the latter by a space, the movable keels being attached to the movable beams, which are attached to the translation frame and arranged at the same height as the stationary refractory beams in the intermediate position, the furnace further comprising a plurality of skirts (70) attached to the other movable beams defining the separation space and dipping into longitudinal water tanks (40) arranged in line with the separation spaces and attached to one of the beams defining a separation space.
(FR)
Four à longerons mobiles comportant des chenets mobiles (10C) et fixes, respectivement supportés par des quilles mobiles (12Q) et fixes, et des moyens d'entraînements agencés pour déplacer un châssis de levage (2) et un châssis de translation (3) selon un cycle de déplacement rectangulaire présentant deux positions verticales et une position verticale intermédiaire selon laquelle les chenets mobiles sont à la même hauteur que les chenets fixes, le four comportant en outre des longerons fixes et mobiles (LRM), les longerons mobiles étant disposés entre les longerons fixes et séparés de ces derniers par un espace, les quilles mobiles étant fixées sur les longerons mobiles qui sont fixés sur le châssis de translation et disposés à la même hauteur que les longerons réfractaires fixes dans la position intermédiaire, le four comportant en outre et une pluralité de jupes (70) fixées sur l'autre longeron mobile délimitant l'espace de séparation et plongeant dans des bacs à eau longitudinaux (40) disposés au droit des espaces de séparation et fixés sur l'un des longerons délimitant un espace de séparation.
