Abstract: Material properties were optimized through the linkage of numericalsimulation with the real rolling pro- cess. A few different steel grades for bars and wire rode were taken as the examples.The examples.The commerical FEM code MARC/MENTAT was used for the numerical simulation of the three - dimensional elas- toplastic rolling process coupled with temperature.The simulation calculation for temperation for temperature control in- side the rolling mill was carried out by use of the SMS - developed CCT system (controlled coling technolgy). New rolling - technological precess was developed for bars and wire rods based on the numerical results.Steel 38MnSiVS5 and steel 41Cr4 were taken as the examples.
