ABSTRACT:
A beam structure is described for supporting rails that carry wheeled cover carriages employed to close the openings of chambers in an industrial furnace of the soaking pit type. Each beam is disposed on the median wall between adjacent chambers and is arranged to mount a pair of rails, each of which is associated with one of the two adjacent chamber openings. The beam is structured and arranged to rapidly dissipate heat acquired during periods of furnace operation and especially due to exposure to the interior of the furnace when the associated cover is removed to thereby protect against undue thermal stressing. Ancillary insulating means may be appended to the structure in the most severely affected regions thereof.
