Abstract

The refractory unit comprises a body which has first (1a) and second (1b) end surfaces, an external wall (1c) and an internal wall (1d). The internal wall defines a flow passage (7) extending between the two ends of the body. The external wall comprises a series of alternate concave portions (4 ) which correspond to similar concave and convex portions (5) of the internal wall. The concave and convex portions are arranged perpendicular to the longitudinal axis of the unit.
