Results of study of wear of rollers of the "NShS 2000" rolling mill of the joint-stock company "Severstal" are given. The study technique and special devices applied for the study are described. Wear profiles of the roll body and wear dynamics for back-up rolls are determined depending on the quantity of the rolled metal. Causes of creating of doughnuts on back-up rolls are given. It is shown that the study of wear profile sizes and dynamics of changes allows one to choose more seriously the operation to shape rollers with the use of shaping mills and its correction by the working rolls according to a degree of a wear of back-up rolls.
