Simulation of Bending of Heavy-Duty Components of Stands in a Five-Stand Longitudinal-Wedge Mill

Resumo

A longitudinal-wedge mill of new design is proposed. We present the analysis of the results of mathematical modeling of the elastic deformation of heavy-duty components of the stands of the new mill with the use of the procedure of computer simulation by the finite-element method in the PATRAN-NASTRAN environment. The influence of changes in the diameter of working rolls of the longitudinal-wedge mill on the elastic deformation of heavy-duty components of the stands of the mill is determined. It is shown that the new mill is characterized by a fairly high stiffness of the structure of stands and satisfies the conditions of strength. It is indicated that the process of rolling of strips on the proposed mill makes it possible to obtain finished rolled products without variations in thickness in the longitudinal and transverse directions. As a result of modeling of elastic deformation of the heavy-duty components the stands of the new mill, we develop special measures for their modernization.
