| Zusammenfassung: | The invention relates to a heat-conducting roller (1), which has an inner shaft (2) for supporting loads and an outer sheath part (4) for processing the surface of a fiber web, wherein the outer sheath part is adhesively fixed on the inner shaft to form a flowing space for a heat-conducting medium. The outer sheath part is made of quenched steel, and the steel is quenched and annealed at the temperature of 300-350 DEG C, so that the hardness of the outer sheath is 450 HV at least. The invention also relates to a manufacturing method of the heat-conducting roller (1). |
