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.

Abstract: The improvement in a walking beam oil country tube reheat furnace comprises a first row of burners positioned in spaced relationship and transverse the furnace hearth with each of the burners containing a refractory housing positioned in the limited space between the walking beam pass line and the hearth of the furnace. The burner includes a burner body and a centrally disposed fuel tube so as to define an annular air chamber thereabout. The burner includes a 90.degree. bend so as to fire in parallel relationship to the pass line. The method of retrofitting a top fired walking beam furnace includes inserting at least one unitized bung of said spaced burners through the furnace floor and into the space between the pass line and floor and firing the burners in parallel relationship with the pass line.

Abstract: A device is described for feeding bars and tubes into a treatment furnace. The device comprises a rotary drum positioned in front of a long horizontal opening provided in the sidewall of the furnace for receiving a bar and introducing it into the furnace through the opening. The device is characterized by a pair of arms which are articulated around an axis outside the furnace and parallel with the drum and which are designed to receive the bars supplied by the drum and to lay them gently down in the furnace, e.g. on the walking beams of a walking beam furnace.

Abstract: In a slab heating furnace of walking beam- or pusher-type, particularly for the heating of steel prior to the hot working of the steel, skid beams are supported by water-cooled posts. In order to reduce the number of the water-cooled posts from that in the prior art, a post head having a trough shaped portion is stationarily located on each of the posts. The length of the post head is longer than the outer diameter of the post provided with said post head. The total withdrawal of heat from heated steel to all of the post heads is considerably small, because the number of posts is reduced from that of the prior art due to the structure of the post heads. The posts are preferably arranged in a zigzag pattern.

Abstract: The technical province of this invention is the heating in a furnace or kiln of metallurgical products principally. The invention relates to a heating method and means for imparting to mutually spaced products resting on the hearth of a kiln of this kind successive individual advancing motions, each consisting of alternating elemental motions, of which one at least is of length different from that of the others. The advantage of the invention resides primarily in the recovery of the heat accumulated in the hearth on the uncovered parts thereof and its transmission along successive zones to the undersurfaces of the products being treated, with dwelling times in the kiln and a degree of filling thereof enabling maximum efficiency to be obtained.
