OPTIMIZATION OF MATERIAL PROPERTIES THROUGH THE LINKAGE OF SIMULATION CALCULATIONS WITH THE REAL ROLLING PROCESS OF DIFFERENT STEEL GRADES FOR BABS AND WIRE ROD

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.
