Abstract

L'invention concerne un four métallurgique rotatif horizontal comportant des moyens de refroidissement à l'extrémité de décharge du four. Les moyens de refroidissement comprennent un serpentin de refroidissement annulaire 20 entourant l'extrémité de décharge 16 et dans lequel circule continuellement un liquide de refroidissement propulsé, par la force centrifuge, à partir d'une auge d'alimentation annulaire 22 entourant le four avec lequel elle tourne jusqu'à une auge collectrice stationnaire 28 montée autour du four. L'invention est applicable notamment aux fours métallurgiques de fabrication de fer et d'acier.
