Моделирование температурных условий прокатки длинномерных рельсов на универсальном рельсобалочном стане

Abstract

The estimation of the roughen distribution of the metal temperature in length and cross section of a peal at rolling rail R65 on universal rail-beam mill. Calculation and modeling of temperature to give consideration to the DEFORM-3D, adapted to the rogue rolling conditions, taking into account the loss of heat radiation and heating of metal from the strain. Temperature exercise negatively influence on mechanical properties and straightforwardness rails. Depending on distribution of the metal temperature in length and cross section of a peal can be arranged heat treatment either in water mixture or water-air mixture.
