ABSTRACT:
A furnace work supporting roll and a spare work roll are mounted on a frame in diametrically opposed positions with the spare roll normally out of the furnace. The frame is mounted on an axis parallel to the roll axis and equal distance therefrom. A water cooled shield is mounted on the frame between the rolls to protect the spare roll from the heat of the furnace and has an outer surface with a diameter equal to that between the outside of the rolls. To inspect and/or remove the work roll from the furnace, the frame is rotated so that the position of the rolls are reversed. A water cooled heat shield is provided at the ends of the diameter perpendicular to the diameter through the roll axes at a distance equal to that between the outside of the rolls. A roll supporting table beneath the position of the spare roll is movable toward and away from the frame.
