Abstract

A turn-lock fastener for the discharge hole at the bottom of a metallurgical vessel is characterised in that a discharge sleeve (3) with a slanted outlet channel (5) is set into the lower terminal section of a nose-ring block (1). A mirror-symmetrical sleeve (3a) to the discharge sleeve (3) has a complementary terminal surface (7a) which lies against the lower horizontal terminal surface (7) of the discharge sleeve (3). The sleeve (3a) is set into a spout (10) capable of rotating with respect to the fixed nose-ring block (1) about a vertical axis. In a determined position of rotation (open position) of the spout (10) the opposite openings of the outlet channels (5, 5a) in the sleeves (3, 3a) are aligned and in other positions of rotation (closing position) they are partially or completely separated from each other.
