Patent Number: 6,167,942

Title: Strip casting apparatus

Abstract: Twin roll caster for casting metal strip. Metal is delivered through a distributor (18) and delivery nozzle (19) between a pair of casting rolls (16) to form a casting pool (30) supported on rolls (16) and confined by end plates (56). Rolls (16) are rotated to deliver cast strip downwardly from the nip between them. Rolls (16) are mounted on carriers (104) moveable to allow rolls (16) to move bodily toward and away from one another. Biasing units (110, 111) act on the roll carriers (104) to force them against central stops (107) and to provide roll biasing forces. Stops (107) are adjustable to set the width of the nip between the rolls (16). Biasing units (110) comprise biasing springs (112) whereas biasing units (111) comprise hydraulic actuators (113).
