Abstract
A composite table roll for use in roll tables in metal rolling mills, particularly for handling hot metal workpieces, having a sleeve portion which is tightly secured to an underlying arbor only at the axial mid-portion so that the end-portions of the sleeve are not in contact with the arbor sufficient to cause any significant heat conductivity thereacross and the end-portions are free to thermally expand with reference to the arbor to thereby greatly minimize any thermal distortion of the arbor in the event a hot metal workpiece becomes stalled on the roll table.
