Abstract

A purge plug which is adapted to be replaceably attached to the bottom (3) of a metallurgical vessel (1) for purging gas (21) through a heat (2) in the vessel. The purge plug comprises an external, essentially sleeve-shaped body portion (9) and an internal, truncated conical body portion (11) of ceramic material. Between these a gap (12) is arranged which extends between the end faces (14, 15 and 16, 17) of the body and a casing (7) encloses the body. The internal body portion (11) is movable in relation to the external body portion (9) and biased by a resilient means (18) in a direction towards the heat (2) to seal the gap (12). The gas is fed to the external end face (14, 15) of the body in order to, at a predetermined pressure, flow through the gap (12) to the internal end face (16, 17) of the body and into the heat (2). A rigid bottom plate (18) is attached in a gastight and fixed manner to the portion (23) of the casing (7) protruding from the external end faces (14, 15). The resilient means is formed by a protruding portion (23) of the casing (7) and this portion (23) comprises an annular, bent area (24).
