Abstract (en)

Process for closing and opening a tapping channel (4) arranged in the base of a melting vessel (1) comprises closing the channel during the melting process on its lower end using a slide and filling the channel with a blocking liquid (7) from below. The blocking liquid does not mix with the melt. An Independent claim is also included for a blocking device (10) for closing and opening a tapping channel arranged in the base of a melting vessel. Preferred Features: The introduction of the blocking liquid is carried out by applying an external pressure with displacement of the melt in the channel.
