TWIN ROLL CASTING MACHINE
Chilled rolls 1, side weirs 2 and a molten-metal delivery nozzle 4 are provided. Contiguous with bottoms of end faces of the nozzle 4 are baffles 11 which are projected in a casting pool 8 toward the side weirs 2 to suppress stream of the molten metal into a nip G between the rolls. Thus, the hot mo...

| description | Chilled rolls 1, side weirs 2 and a molten-metal delivery nozzle 4 are provided. Contiguous with bottoms of end faces of the nozzle 4 are baffles 11 which are projected in a casting pool 8 toward the side weirs 2 to suppress stream of the molten metal into a nip G between the rolls. Thus, the hot molten metal just after poured into the pool does not instantly reach the nip G along the side weirs 2; the molten metal decreased in temperature with lapse of time after the pouring is caused to stream into the nip G as the rolls are rotated. As a result, eliminated is belated formation of solidified shells at and adjacent to outer circumferential edges of the chilled rolls 1. Thus, the strip 3 delivered from the nip G between the rolls 1 has no reduced thickness at regions adjacent to lateral edges of the strip and the strip 3 can be obtained which has uniform thickness throughout the width of the strip. |
