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.

A roller guide according to the present invention includes a frame mount surface portion and a roller mount surface portion to be mounted to a car, which are formed by plastically deforming a single steel plate. Thus, the number of components is reduced to significantly shorten assembly time. In addition, processing costs are also significantly lowered.

A method for making recesses in the surface of a roller for a rolling press. A thermal treatment is applied to a cylindrical roller surface by heating the surface in a region of the desired recesses until the material properties of the roller surface change permanently, i.e., even after cooling, with respect to the hardness of the roller material. The thermally treated regions produce a softer material in those regions than in the surrounding surface of the roller. By virture of a first start-up of the rolling press with abrasive material to be comminuted, the desired profiling is formed spontaneously due to a wearing down of the soft regions to form the desired recesses. The thermal treatment represent a particularly simple and cost-effective method for profiling rolling rollers, and in particular, rolling rollers which have already become worn, which that thereby be readily refurbished.

A roller for forming heat transfer elements may include a central shaft and a plurality of roller elements. The plurality of roller elements may be stacked on the central shaft. Each roller element defines an outer periphery, which is configured to include a geometrical characteristic thereacross. The stacked roller elements, either stacked on the central shaft or stacked without using the central shaft, configures the roller with a circumferential surface corresponding to the geometrical characteristic of the stacked roller elements, to form the heat transfer elements corresponding to the circumferential surface.

Disclosed is a soft tube of a sheet conveying portion of a sheet conveying roller, including: a region with irregularities in an outer peripheral surface of the soft tube. The region has a root mean square slope Sdq within a range of 0.03 to 0.50.
