ABSTRACT:
A carrying device for supporting a charge in a reheating furnace is disclosed. The carrying device has several tubular supports through which coolant flows, said tubular supports being provided with high-temperature-resistant riders. Each rider has a top section and a bottom section. The bottom section is limited by sides which are inclined towards each other in the direction of the head section and form protruding steps with the latter. Plate-shaped heat insulation elements supported by support cams are inserted in the resulting recesses. The plate-shaped elements, which are not subject to wear from the movement of the riders, cover the sides of the bottom section of the rider and provide heat insulation for the bottom section. Thus the bottom section is protected against wear-promoting overheating and heat is also prevented from passing from the charge to the bottom section. On the contrary, the plate-shaped elements radiate heat to the charge, thus avoiding the formation of cold charge areas.
