Influence of the Rolling Loads on the Stress in the Roll Surface Layer
Original language description
The roll surface is periodically loaded by thermally and mechanically inducted stresses during the rolling. This leads to thermal fatigue, wear, corrosion and contact fatigue. This paper describes the processes of roll cooling simulation and verification of the structural damage of the roll surface layer with a focus on the influence of the rolling loads. The most critical factor for thermal cracks is a tensile stress which appeared in the roll surface layer in the cooling area. In addition, the load like rolling pressure or shear stress can significantly decrease the product life of roll through the facilitation of the thermal crack forming and propagation to the roll core. Three different loading configurations were created based on the real hot strip mills. These configurations had the same cooling on the roll but they varied in the rolling load. The task can be divided into two parts – structural and thermal analysis. The thermal analysis is calculated first. It produces the thermal load in the ro
