Abstract

La présente invention concerne le domaine des installations métallurgiques. L'invention concerne en particulier un système de transport pour charger un récipient de fusion métallurgique, de préférence un four à arc électrique, qui est déplacé d'une station de réception à une station de décharge. La présente invention aborde le problème de la création d'un système de transport qui a un récipient interchangeable (2), le récipient ne nécessitant pas de mécanisme d'ouverture (6) pour un rabat de récipient (5) et le récipient (2) n'ayant pas besoin d'être relié à une alimentation électrique. Le problème est résolu par le cadre d'inclinaison (3), qui a une unité d'ouverture (6). Le rabat de récipient (5) présente un nez d'entraînement (5b) qui est inséré dans l'unité d'ouverture (6) lorsque le récipient interchangeable (2) est placé en position sur le cadre d'inclinaison (3). L'unité d'ouverture (6) déplace le nez d'entraînement (5b) de telle sorte que le rabat de récipient (5) peut être déplacé entre la position fermée et la position ouverte.
