Abstract
A method for making either a ringless annealing furnace roll or a furnace roll having a series of spaced rings for supporting a metal strip being removed from an annealing furnace. Each ring is centrifugally cast with an outer rim of a steel alloy that is relatively insoluble with respect to the alloy of the strip being transferred from the furnace, and an inner liner of an alloy that can be readily welded to a roll. The inner liner material is fused to the rim material to form a composite ring.
