Disclosed is a refractory connection between a vessel containing a metal melt and an outlet device for the metal melt, particularly a refractory discharge for molten steel. In order to prevent freezing of the metal melt and deposits of components of the metal melt on the inner wall surface of the discharge wall, a discharge inner wall is made wholly or partially of a ceramic material which is electrically conductive at least at a temperature at which the metal remains liquid and which may be inductively heated by means of an induction coil.
