ABSTRACT:
A roller for furnaces, is used with a plurality of rollers substantially parallel to each other. The roller is provided with a plurality of annular collars which are side by side and spaced apart. The annular collars are cooled by means of a flow of cooling fluid which is oriented transversely with respect to their axis and parallel to their median plane. The annular riders are made in tubular form and may be of toroidal form and are connected separately each to the supply duct and to the return duct for the cooling fluid. They may also be formed by the individual turns of a tubular spiral or by a number of successive segments of a spiral which are connected via their ends to the supply duct and to the return duct.
