摘要： Molten metal is introduced between a pair of parallel casting rolls (16) of a twin roll caster by metal delivery apparatus comprising a distributor vessel (18) and delivery nozzle (19) to form a casting pool (10) above the nip (30) between the rolls (16). The rolls (16) are rotated so as to cast a solidified strip (20) delivered downwardly from the nip (30). Casting of the strip is terminated by stopping the flow of metal to the delivery apparatus (18, 19) and allowing the quantity of molten metal in the delivery apparatus to run down to a reduced quantity at which there is still molten metal in the casting pool and then moving one or both casting rolls laterally to increase the gap between the rolls whereby to interrupt formation of the strip and allow downward discharge of the remaining metal through the increased gap between the rolls.

摘要： 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.
