Abstract: The roller exhibits a support body which is provided with a plurality of support disks. Insulating layers are arranged between the support disks. A heat-resistant cable surrounding the support body in several coils is embedded in each insulating layer. The insulating layer consists of fiber material which is sprayed on at the same time as the cable is wound around the support body. The cable provides a firm and lasting connection of the insulating layer to the support body.

Abstract: A device for carrying a charge in a reheating furnaces comprising at least one skid pipe through which a cooling fluid flows, the skid pipe having at least one rider provided with at least one surface to support said charge running off center in the longitudinal direction of the skid pipe. According to the invention neighboring surfaces are laterally spaced relative to each other and run at least partially to the side of the skid pipe. Charge exposure to the relatively low temperature around the skid pipe is kept at a very low level and charge temperature is therefore very uniform.

Abstract: The system comprises at least one coolant-carrying tubular support carrying at least one rider. The latter consists of a heat-resistant cast housing provided with at least one cutout into which a ceramic carrier is inserted. The carrier is of sufficient compressive strength even at a temperature in excess of 1,200.degree. C. The housing remains at a temperature below 1,200.degree. C. and therefore provides a very good support for the carrier which it holds and transfers the loads that occur into the tubular support. The housing is detachably connected with the tubular support by means of a bolt.
