We propose a way to increase the wear and crack resistance of the main working tools for roller mills. Bimetallic rollers (with a diameter of 252 mm and a length of 1620 mm) are produced by sequential pouring of alloys with similar temperatures of phase transformations. The microstructure, phase composition, redistribution of alloying elements, and the properties of bimetallic materials are studied. The results are used as a basis for the development of a technological process for the production of bimetallic milling rollers by the method of centrifugal casting. The implementation of this method makes it possible to improve the reliability and durability of rollers in the course of their operation.
