- Abstract
The paper presents simulation of hot rolling process of profile I, to determine the state of tension in the rolling cylinders, using professional simulation software COSMOS / M 2.5. Initial data from the simulation program (the application of cooling water and rolled pieces temperatures) are data taken in Romanian industrial companies. The simulation is performed for two cases of rolling: the application of cooling water on two and four surfaces at a temperature of 800ΰC, 850ΰC respectively. Recorded values are presented for thermal stress in the two cases of simulation, thermal stress inducing the thermal fatigue (this influencing durability cylinders rolling operation).
