Abstract

La présente invention concerne un bloc de goulotte possédant un débit de décharge uniforme de plomb fondu, le bloc de goulotte possédant des conduites internes et externes horizontales en son sein pour fournir le plomb fondu, fourni au moyen d'une conduite d'admission de plomb fondu, vers un canal d'écoulement de plomb fondu, et possédant une pluralité d'orifices de décharge de plomb fondu, en communication verticale, sur les conduites internes et externes, les diamètres des orifices de décharge de plomb fondu sur les conduites internes et externes rétrécissant progressivement depuis l'extrémité avant vers l'extrémité arrière associée. Selon la présente invention, le plomb fondu provenant de tous les orifices de décharge de plomb fondu est déchargé à un débit uniforme, ce qui permet qu'un niveau défini de plomb fondu soit maintenu dans le canal d'écoulement de plomb fondu du bloc de goulotte lorsque le canal d'écoulement de plomb fondu associé est en cours de remplissage par le plomb fondu, ce qui amène les vitesses de remplissage et de refroidissement du plomb fondu dans le moule à être uniformes et ce qui provoque la réduction de la variance de la structure cristalline de chaque bande, et donc l'aptitude à la commercialisation du produit en batterie peut être améliorée avec la présente invention très utile.
