TUBULAR ROLL FOR A CONTINUOUS CASTING MACHINE

摘要

A roll for guiding a cast metal strand emanating from a continuous casting machine comprises a cylindrical envelop rotatable about its axis by contact with the cast metal strand. A pair of tubular spindles project from opposite ends of the envelop coaxially fixed thereto and rotably mounted in the region of the outer ends in ball bearings fixed to the machine frame. A central tubular arbor equiped in a central portion thereof with an inductor extends with radial clearance through the spindles and is supported at end portions thereof projecting beyond the spindles in cradles fixed to the machine frame. A key or the like is provided in one of the cradles engaging in a cutout of the central arbor to prevent rotation of the latter during rotation of the envelop and the spindles connected thereto.
