Abstract

The invention relates to a gas purging device for installation in a metallurgical vessel, said device having the following features in a position installed in the bottom of the metallurgical vessel:

a lower, largely gas-tight base part,a gas line runs in the base part from a first end in the region of a first outer face of the base part to a second end in the region of a second outer face of the base part,the second end of the gas line is formed as a first portion of a coupling,a second portion of a coupling is located in the region of an outer connection face of a functional part, by means of which the functional part rests against the base part,a gas distribution device runs in the functional part from the second portion of the coupling, through the functional part, to at least one free surface of the functional part formed as a gas outlet face,the base part and functional part are each made of a refractory ceramic material.
