Stress Analysis And Optimization Of Rolling Mill Housing Using Cae

Rolling is defined as a process in which metal is formed through a pair of revolving rolls with plain or grooved barrels. The metal changes its shape gradually during the period in which it is in contact with the two rolls. Rolling is a major and a most widely used mechanical working technique. A Rolling mill is a complex machine for deforming metal in rotary rolls and performing auxiliary operations such as transportation of stock to rolls, disposal after rolling, cutting, cooling, melting. The problem of failure of Rolling Mill Housing was there in industry, which can be efficiently solved by using CAE. The present work involves the optimization of Rolling Mill Housings design for rigidity, to control the deflection of the housing for better gage control of the material being rolled. The Housing stress distribution has been analyzed using analysis software CATIA from which maximum static stress at critical areas have been calculated. Structural behavior of housing under the given loading and boundary conditions using an analytical model is very difficult. Therefore 3D solid model was chosen in order to predict the stress and strain response detail.
