Abstract
A technique for selecting roll contouring for sheet-rolling production is presented, which differs from the known ones by using a spatial finite element model of the roll system and a continuous description of the barrel shape (roll profile). The calculation part of the technique is based on the determination of the elastic deformation curve of the working roll in contact with the rolled metal based on the finite element model of the roll system, which considers the roll contouring, as well as the formation of the transverse profile of the rolled product. This technique provides a solution to operational technological problems of improving the quality of products and the rolls durability. As a result of the methodology implementation, a new roll profiling system of the quarto mill 5000 was obtained, which provides a reduction in peak roll contact stresses and an increase in the resistance of back-up rolls in compliance with the requirements for the geometric parameters of wide steel sheets. Proposed method for selecting the roll profiling in the form of continuous curves along the barrel length can be used for various types of rolling mills and the roll systems profiles used.
