Abstract

The invention relates to a tapping device for a crucible (1), especially a converter which is provided with a tapping channel (2) and a discharge (2b). Said tapping device comprises a refractory nozzle (26) that can be put onto the discharge (2b) coaxially relative to the tapping channel (2), thereby sealing the discharge, or that can be pressed in a sealing manner onto a refractory adapter part (10), which has an opening (10a) and can be fastened on the discharge (2b), approximately coaxially in relation to the tapping channel (2) and the opening (10a). The aim of the invention is to achieve practically constant, optimum tapping times for all batches in simple manner. For this purpose, the nozzle (25) is positioned by means of a nozzle changer (30) and is replaced with a new nozzle (25'; 45') after every tapping or after two or more tappings.
