  • Casting roll for an installation for continuously casting on one or between two rolls
    Patent number: 5613546
    Abstract: A casting roll for continuous casting of metals. The roll comprising a core (2) and a sleeve (3), coaxially arranged one with respect to the other. The sleeve is axially coupled to the core by a inward projection (33) on the sleeve which abuts a shoulder (24) on the projection. The projection and the shoulder are located in a plane (P) substantially median with respect to the roll. The sleeve is radially centered on the core by flanges (5) and (6) which are elastically coupled together. The flanges and sleeve have relieved surfaces (37) which allow the sleeve to expand axially without bowing. The invention is particularly well suited for continuous casting thin metallic strips, especially steel strips, between two of these casting rolls.
