Refractory gas purging plug

Refractory gas purging plug (1), comprising the following features:

• 1.1 a body (2) of refractory ceramic material;
• 1.2 the body (2) extends from a first end (3) of the body (2), where gas can be introduced into the body (2), to a second end (4) of the body (2), where gas can be discharged from the body (2), opposite the first end (3) of the body (2);
• 1.3 the body (2) comprises a first part (7) made of porous, permeable refractory ceramic material which extends from the first end (3) of the body (2) to the second end (4) of the body (2);
• 1.4 the body (2) comprises a second part (9) made of refractory ceramic material which extends from the first end (3) of the body (2) to the second end (4) of the body (2), the second part (9) comprising gas channels (10) with a defined geometry extending through the second part (9) from the first end (3) of the body (2) to the second end (4) of the body (2);
• 1.5 a first gas distribution chamber (18) disposed at the first end (3) of the body (2);
• 1.6 a second gas distribution chamber (20) disposed at the first end (3) of the body (2);
• wherein
• 1.7 gas can be introduced into the first part (7) via the first gas distribution chamber (18);
• and
• 1.8 gas can be introduced into the second part (9) via the second gas distribution chamber (20).
