Abstract

The present invention relates to the casting of molten metal, in particular of molten steel. The invention relates to a device allowing a safe opening of a blockage of a taphole of a metallurgical vessel equipped with a slide gate valve comprising a mobile plate, for example of a metallurgical ladle. The opening device of the invention comprises a head (3), a pushing rod (2) a guiding tube (1) and transmitting means (4,61,62,63). According to the invention, the opening device is actuated by the actuation of the mobile plate in the slide gate valve.
