Abstract
Metal delivery nozzle 19 for a twin roll caster is formed in two pieces 19A disposed end to end with a gap 50 between them. Each nozzle piece 19A is mounted on two pairs of mounting brackets 60. Outer end parts of the nozzle pieces 19A are constrained by the interengagement of mounting bracket projections 71 and nozzle recesses 72 such that thermal expansion of the nozzle pieces is accommodated by inward movement into the gap 50. Projection 71 may be upstanding lugs and nozzle recesses 72 may be slots in the undersides of nozzle side flanges.
