Abstract

The invention relates to a refractory ceramic gas bubbling element for a metallurgical crucible and to a corresponding gas bubbling system comprising such a gas bubbling element. The gas bubbling element comprises the following sections, namely between a first end at which the gas is supplied, and a second end at which the gas is discharged: at least one gas supply tube leads into the first end; the gas supply tube leads into a gas distribution compartment; a plurality of capillary channels extend from the first gas distribution compartment to a second gas distribution compartment; at least one gas channel, whose cross-section is larger than that of a capillary channel, extends from the second gas distribution compartment to the second end of the gas bubbling element.
