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.

Abstract: Gas purging element (10) for metallurgical applications, comprising the following features in its mounted state: a ceramic refractory body (10, 30) with a lower end and an upper end, the upper end features an upper front surface, the lower end features a lower front surface (12), a depression (20) extends from the lower front surface (12) into the lower end of the ceramic refractory body (10), the depression (20) comprises a first part (16, 16?, 16?) of a detachable, form-fit connection to a gas connection element (50), a fluidic connection for a treating gas through at least one gas permeable section (30) of the ceramic refractory body (10) is provided between the depression (20) and the upper front surface.

Abstract: The invention relates to a gas purging element at a metallurgical vessel as well as a corresponding gas supply pipe.
