Abstract: A taphole for discharging a metallurgical vessel of an electric arc furnace and associated furnace and discharging method The invention relates to a taphole (14) for discharging a metallurgical vessel (12) of an electric arc furnace (10), the taphole (14) comprising a central conduit extending along a longitudinal axis (X) between a top end (32) opening into the vessel (12) and a bottom end (34) for discharging molten steel outside the vessel (12) into an enclosure (24), such as a ladle. The central conduit comprises successively an upstream portion and a downstream portion, and a throttle arranged between the upstream and the downstream portions. The throttle has a constricted cross-section compared to a cross-section of the upstream and downstream portions, so as to generate a Venturi effect when discharging the vessel (12) through the taphole (14).
