Abstract
Spaced-apart skid frames support workpieces in a reheat furnace. Each skid frame includes a plurality of spaced-apart rails arranged to extend along the path of travel of the workpieces in the furnace for engaging the underside faces of the workpieces. A tubular top cord member carries rail members. Two horizontally-spaced tubular lower cord members extend parallel and below the top cord member. Tubular web members extend angularly between joints which intersect with the top and lower cord members to form a lattice structure having triangular open spaces between the top cord member in each of the lower cord members for passage or radiation to heat the underside faces of workpieces along either side of the skid frames. Coolant is supplied to each of the top and lower cord members and the tubular web members to prevent overheating.
