Study of the work roll cooling in hot rolling process with regard on service life

Popis výsledku v původním jazyce

Operational conditions and many studies confirmed that the work rolls cooling in hot rolling process have significant impact on damage and service life. The specific approach based on the numerical simulation and experimental results of the work roll cooling optimization and service life improvement is presented in this paper. The 3D finite element model was prepared for the numerical simulations of the work roll cooling. The FE model represents circular sector of the work roll. The model is fully parametric. It is capable to simulate a roll with any diameter, any thickness. Each of the model parameters can be easily changed based on user requirements. The stress state is calculated by ANSYS in two steps. At first, the thermal conditions as starting temperature of the roll, cooling intensity and so on are applied and time dependent thermal analysis is performed. The temperature field of work roll is obtained from transient thermal analysis and is used as thermal loads in second step. I
