Profiling Practice for S-shaped Rolls with Residual Thermal Crown
The paper discusses the way to improve the methodology of grinding S-shaped working rolls by taking into account its thermal deformations, arising from the contact with the hot strips during the campaign. An algorithm of grinding working rolls in a hot condition using the mathematical model of the thermal expansion, allowing predicting the change of the profile of S-shaped rolls was developed. The paper leads the basic points and stages of approbation of methodology and results of research.
