抄録

A method of numerical simulation for hot caliber rolling is proposed, in which deformation of a material is analyzed in an ordinary manner by three-dimensional rigid-plastic FEM, while temperature distribution in the material is calculated using a new combined method of three-dimensional FEM and one-dimensional FDM. First, the method is proven to be effective through analysis of single-pass rolling with various velocities of roll. Next, the method is applied to a simulation of the deformation and temperature of the material in an actual caliber rolling process, in which a round bar is produced from a square billet after 16 passes and strain and temperature distributions in cross sections of the material are obtained. Finally, the calculated shape and surface temperature of the material are found to agree well with measured ones.
