Abstract
A furnace roller assembly having a fluid-cooled shaft that is covered by an interface performance material comprising both ceramic millboard and a wire brush bristled-material is disclosed. The roller assembly can be used as part of a conveyance system in a finishing mill to support and transport steel sheet through an annealing furnace. The fluid-cooled shaft and the ceramic millboard plus wire brush interface performance material arrangement provide the means to provide effective insulation for the shaft while preventing degradation of the covering on the shaft.
