摘要： PROBLEM TO BE SOLVED: To provide a rolling mill capable of obtaining rolled materials of copper and a copper alloy having excellent surface quality while suppressing occurrence of roll mark, and to provide a method of manufacturing the rolled material.
SOLUTION: The rolling mill has a pair of upper and lower work rolls (1, 1) for rolling rolled materials (4) consisting of copper or a copper alloy, and at least one pair of rolls for supporting the work rolls (1, 1). The work roll (1) is a forged steel roll with the Shore hardness of its surface being ≥95 HS. The Shore hardness of a surface of an intermediate roll (2) or a backup roll (3) in contact with the work roll (1) is lower than that of the work roll (1) in a range of ≥25 HS and ≤40 HS.
