Abstract
In a furnace 10, wherein work-pieces 11 are pushed through the furnace chamber, a final heating zone 18 includes water-cooled skids 24 over which the workpieces 11 can be pushed, multiple support members 40 disposed between the skids, and means for moving the support members or the skids for transferring the workpieces from the skids to the support members, whereby the skid marks are erased by heat from burners 22 while the workpieces are on the support members. As shown, the support members 40 include an upper section 43 with a plurality of legs 44 joined thereto, the upper section 43 being formed with two vertical levels 43a, 43b, and having a refractory cap extending over the surface 43b. Each member 40 is supported by an upright support structure 50 which includes a refractory block 64 for receiving the legs 44. All of the support structures 50 are coupled together by a pair of elongated transversely extending I-beams 80, the structures 50 being supported on the floor 53 by pairs of laterally spaced drive units 82 and guide units 84. In operation, when workpieces 11 are being pushed through the furnace chamber, the horizontal plane including the upper surfaces of the refractory cap 46 is disposed below the horizontal plane including the wear bar 35 on the skids 24. However, as soon as the workpieces are at rest, the assembly of members 40 and support structures 50 are moved under the action of the drive units 82 such that the plane of the refractory caps 46 will be inclined to and above the wear bars 35 of the skids 24. Other embodiments include means for raising and lowering the skids 24, the support members 40 remaining stationary.
