Abstract: An electrolytic processing method for electrolytically processing the surface of a metallic member. A paste containing an electrolyte is prepared by mixing a paste-forming agent with a liquid electrolyte. The paste is placed between the metallic member and an opposing electrode. The metallic member and the opposing electrode are connected to an electrical power supply so that an electrical current is made to flow between the metallic member and the opposing electrode through the paste containing electrolyte, whereby the surface of the metallic member is electrolytically processed. Descaling, passivity treatment, coloring, polishing, plating and other electrolytic process can be performed on any type of metallic member at any desired place, by suitably selecting factors such as the compositon of the paste, condition of the electrical power supply and so forth.

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.
