ABSTRACT:
A conveyor for a furnace includes a walking beam unit mounted within an elongated opening through the bottom wall. A longitudinally-moving H-shaped support member is located beneath a refractory beam. An expandable tube extends beneath the beam and has a central passageway in the crossbar portion connected in series with the tubular member. Cooling water flows through the expandable tube and the beam passageway. Expansion and contraction of the tube is affected by selectively restricting the exhaust flow of the cooling fluid. An upwardly open channel supports the tube on a roller support to movably mount the beam, tube and channel supports as a unit. A cylinder operator is secured to one end.
