Workpiece charger for heating furnace

Abstract

A workpiece charging unit for a walking beam furnace has an entry table and a charging conveyor positioned exteriorly and interiorly of the entry end opening of the furnace. The charging conveyor can undergo a movement along a generally rectangular path for the receipt of the workpiece from the entry table and for the subsequent transfer of the workpiece onto the fixed beams or rails within the heating chamber where it can be picked up by the walking beam conveyor unit for the passage through the heating chamber. The charging conveyor includes charging beams, a plurality of support posts for the support of the charging beams and frame structure coupled with the horizontal and vertical drive mechanisms.
