摘要

A method for manufacturing a roll for rolling flat metal products having a barrel section coated with a wear-resistant layer and journals formed thereon, and a main body blank which includes a barrel section and two blank journal sections The barrel section is encased with a jacket which is connected, with its edge regions associated with the blank journal sections, in a sealed manner, to the associated end faces of the blank journal sections, and limits a cavity surrounding the barrel section. The cavity is filled with an alloy powder. The wear-resistant layer coating of the barrel section, which forms a substance-to-substance bond with said barrel section, is then formed from said alloy powder through hot isostatic pressing. The jacket is then removed from the barrel section, the blank journal sections are formed into the journals and the barrel section and the journals are finished.
