Roll for continuous casting.

摘要

A continuous casting roll comprises a roll body (1) having a cooling water bore (9) (9a) coaxially therewith, and a sleeve (2) fitted around the roll body (1) and having one end fixed to the roll body (1) and the other end as a free end. The roll body (1) has a trunk portion (1a) and a shaft portion (1b) (1b) at each end of the trunk portion. A plurality of cooling water channels (14) provided between the trunk portion (1a) and the sleeve (2) extend in parallel axially thereof and have opposite ends in communication with the water bore (9) (9a). The sleeve (2) is fitted around the roll body (1) by a shrink fit the interference of which decreases steadily from the fixed end toward the free end to permit free thermal deformation of the sleeve (2) toward the free end.
