Abstract
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.
