ABSTRACT:
A hearth construction having a plurality of sections each of which has a first plurality of parallel, stainless steel I-beams connected in spaced relation by a plurality of transverse stainless steel I-beams. The top surfaces of the longitudinal and transverse I-beams are co-planar to provide a furnace floor for supporting work loads to be heat treated. In each section there are three elongated beams with the outer beams in each section having extensions at one end thereof. The ends of the extensions are situated in the furnace vestibule and have chamfered ends to facilitate loading and unloading of the work loads. Each section has a plurality of pairs of pier plates. The pairs are longitudinally spaced along the elongated beams at a distance corresponding to pier blocks which are situated on and extend from the furnace subfloor. The spacing between the plates in each pair dimensionally conforms to the pier blocks. The sections are then installed over the pier blocks with each pair of plates engaging opposite sides of the corresponding pier block.
