    Abstract: A furnace roller for supporting a heated workpiece in a furnace, including a roller body with a roller body outer surface that is rotatable along a roller body longitudinal axis. A tire is attached to the roller body outer surface and is rotatable with the roller body and supports a heated workpiece. The tire is shaped such that a contact interface between a workpiece and the tire continuously shifts in a longitudinal direction, and the tire is helical-shaped. The furnace roller includes at least two helical-shaped tires attached to the roller body in either side of a roller body bisecting centerline. A method for conveying a heated workpiece in the furnace is also disclosed.
