ABSTRACT:
A walking beam furnace has an elongated hearth with a longitudinal slot, and a walking beam is positioned within the slot. The bottom edge of the walking beam is provided with a rack which is engaged by a plurality of crank lever pins which are pivoted in a manner to raise, move forward, and then lower the beam. The pins are actuated by a mechanism positioned on the top of the furnace and connected to the pins by means of vertical actuating arms on the sides of the furnace with the arms being connected to shafts on the bottom of the furnace. The crank lever pins are mounted on the ends of the shafts.
