Impact of Rolling Conditions on Propagation of a Potential Crack

Original language description

The paper reveals information about crack behavior during hot rolling of heavy-gauge products. FEM-based mathematical modeling has been used to investigate the impact of crack shape and rolling parameters on the distribution of the principal tensile stress and the Cockroft-Latham fracture criterion value and on the crack closing capacity. The results clearly show that the crack shape has the most powerful influence on the observed quantities followed by the rolling geometry factors. To find a critical value of the LCK for a specific steel grade and an actual rolling process, a laboratory experiment has been conducted, in which problems related to propagation of initial cracks were detected.
