Abstract
A cooled furnace transport roller comprises a hollow cylindrical roller having an intermediate furnace space portion which is adapted to be positioned in a furnace and with a stub shaft portion adjacent each end which is supported on bearing means located exteriorly of the furnace. A hollow interior tube is located on the interior of the cylindrical roller and is spaced inwardly therefrom and it defines a space between its exterior and the interior of the hollow cylindrical roller for the flow of a coolant gas which is returned through openings of the hollow interior tube and through the interior thereof. A tubular wire net cooling insert is located in the space between the hollow interior tube and the cylindrical roller interior and it is formed with a wire mesh having good heat resistance and good heat conductivity. The mesh is advantageously of wave shaped configurations with the wave formations being disposed with their peaks in touching engagement with the interior of the cylindrical roller and the hollow interior tube and with the waves having a sloping side face so that the faces of the mesh exposed to the gas flow define a substantially closed pattern.
