Abstract

The invention concerns a fireproof ceramic terminal brick for a tapping system in particular in steel converters or electric furnaces composed of several fireproof ceramic founder's bricks arranged in a row, together enclosing a passage opening for the steel smelt, thereby characterized in that the terminal brick is formed in two pieces vertical to the direction of flow of the steel smelt and the lower section in the direction of flow of the smelt is formed as a cylindrical body that can be pressed firmly against the upper section of the terminal brick, arranged above it, in such a way as to seal but remaining detachable from it.
