摘要： A roll polishing apparatus is provided which can suppress cracks on a strip.
Provided are brush rolls 9 which face outer periphery of chilled rolls 1 over axial length of the chilled rolls, respectively, cylinders 10 which urge the brush rolls 9 wholly to the chilled rolls 1, respectively, and cylinders 11 which deform the brush rolls 9 in conformity to crowns of the chilled rolls 1, respectively. By these elements, wires of the brush rolls 9 are uniformly contacted on outer peripheries of the chilled rolls 1 to wipe off oxides adhering to the outer peripheries of the chilled rolls 1.

摘要： 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.
