Abstract

La cuve de préchauffage comporte des parois latérales 2, 3 et 4 électriquement isolées les unes des autres et reliées respectivement par les connexions 5, 6 et 7 aux trois phases du réseau. La forme en étoile de la cuve permet une uniformisation des températures à l'intérieur de la masse de béton. Le déversement du béton chauffé se fait par rotation de la cuve 1 autour de l'axe 16.
