摘要： In the production according to the invention of a roll 1 for the rolling of flat metal products, which comprises a barrel portion 6 that is coated with a wear-resistant layer and has journals 7, 8 formed on it, a main body blank is provided, comprising a barrel portion and two unworked journal portions that have a greater diameter than the barrel portion and a material volume that is at least equal to the volume of the journal 7, 8 of the roll 1 assigned to the respective end face. This barrel portion 6 is enclosed with a sleeve, which is connected by the peripheral regions thereof assigned to the unworked journal portions in a sealing manner to the end faces respectively assigned to it of the unworked journal portions, and delimits a cavity running around the barrel portion 6. The cavity is filled with an alloying powder. Subsequently, the wear-resistant layer 13 that encloses the barrel portion 6 and is connected to it with a material bond is formed from this powder by hot-isostatic pressing. Then, the sleeve is removed from the barrel portion, the unworked journal portions are formed into the journals 7, 8 and the barrel portion 6 and the journals 7, 8 undergo finishing.
