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 bottom plate (18) in a direction towards the heat (2) to close 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). The bottom plate (18) is formed in one piece and comprises an essentially flat, central portion (23) which is attached to the internal body portion (11), a peripheral portion (24) which is attached to the casing (7) and an intermediate, bent portion (25). The central portion (23) and the peripheral portion (24) are essentially parallel to the external end face (14, 15). The intermediate portion (25) is defined by an internal border area (26) and an external border area (27) which smoothly pass into the central portion (23) and into the peripheral portion (24), respectively.
