ABSTRACT:
In a furnace for heat treating of workpieces, a workpiece-engaging element which is adapted to support a workpiece which is to be advanced through and heat treated in the furnace is mounted upon a mounting surface of an elongated, internally-cooled supporting member. The supporting member includes a first section having first walls which diverge from each other in direction away from the mounting surface until the first walls define a maximum spacing therebetween. The supporting member also includes a second section adjoining the first section and having second walls which are spaced from each other at a predetermined distance not exceeding the maximum spacing so as to permit heat to flow towards the underside of the workpiece without being screened by the second walls.
