Abstract: PROBLEM TO BE SOLVED: To provide means for increasing the heat dissipation from a support ring onto a shaft, extending the availability of the support ring with reduced formation of scale thereon, and at the same time, ensuring a reliable torque transmission between the support ring and the shaft. SOLUTION: A water-coolable furnace roller has the shaft supported to the outside of the furnace to be driven in rotation, and is used for conveying a material to be transported, for example, a continuous-cast material through a roller hearth heating furnace provided with the cooling medium ducts 4 and 5 in the hollow space of the shaft and the support ring 7 which is arranged with a receiving bore 1 on the shaft and forms a conveying plane. The furnace roller is characterized in that contact surfaces at the inner diameter of the receiving bore 1 of the support ring 7 and/or at the outer diameter of the shaft 3 are formed as a polygon contour of a substantially constant diameter with the fitting surfaces 6 and 6', i.e., with a so-called weak interference.

Abstract: PROBLEM TO BE SOLVED: To provide a coolable furnace roller mechanism for transferring a continuous-cast material through a temperature-balance-furnace in a continuously casting facility. SOLUTION: In this furnace roller mechanism, at least one fastening ring 8 comprising a metal or its alloy having the highest thermal conductivity and a suitability for cold or hot transformation is used for obtaining an optimal metallic contact without disturbing, to the greatest possible extent, the heat transfer between a support ring 7 and a shaft 3. The fastening ring in a cooling state under pressure is plastically deformed by vertically extending with the heat of the steel bushes 9 and 9' slidable on the shaft to completely abut on the surface portion belonging to each other, and is connected with the shaft 3 so as to transmit a torque in an anti-twisting state.
