Methods for increasing the service durability of cold rolling mill rolls

Various conditions of heat treatment of low-alloy pearlitic steels, medium-alloy martensitic and pearlitic-martensitic steels, and high-alloy ledeburitic roll steels are studied. Practical recommendations for increasing the quality of roll tools are developed. They consist of the application of cyclic heat treatment, including cyclic subzero treatment. The increase in the service durability of rolls after the implementation of these recommendations under industrial conditions is analyzed.
