Abstract
A method of manufacturing an insulated furnace roller includes providing the roller with an insulating refractory castable between the spaced apart tires of the roller and between the outermost tires and the furnace walls, the castable being secured to an arbor of the roller by metal anchors having outer ends that terminate inwardly of the outer surface of the castable, and wherein between the tires and the castable spacer discs are provided and between openings formed by the discs and tires insulation is inserted, the arbor being also wrapped with insulation before the castable is formed on the arbor.
