Abstract
The paper discusses the way to improve the methodology of S-shaped working rolls grinding by taking into account its thermal deformations, which appear during the campaign by the contact with hot strips. An algorithm of working rolls grinding in hot condition is developed by using the mathematical model of the thermal expansion, which allows one to predict changes of the profile of S-shaped rolls. The algorithm and the results of its manufacturing approbation are presented in this paper.
