Abstract

A taphole assembly for a vessel containing a molten solid. The assembly is comprised of a tubular element formed of a refractory material. The tubular element has a continuous passage extending therethrough along a first axis. A socket block formed of a plurality of mating refractory components is provided to hold the tubular element. The socket block has a first convex cylindrical surface on one side thereof and a second convex cylindrical surface on an opposite side thereof. The first and the second cylindrical surfaces are defined about a second axis extending through the socket block. The socket block has an inner cavity dimensioned to receive and to capture the tubular element. A first rectangular saddle block has a first concave recess formed therein that is dimensioned to match and to receive the first convex surface on the socket block. A second rectangular saddle block has a second concave recess formed therein that is dimensioned to match and to receive said second convex surface on the socket block.
