Abstract

The steel rolling process relies heavily on roller entry guides to guide billets onto high-speed rolls. Data from the steel industry indicates damage such as surface cracking and wear on rollers, primarily due to billet dimensional variations and repeated impact loads. This study analyzes the mechanical failure of roller entry guides using Finite Element Method simulations with an Explicit Dynamics approach in ANSYS. With actual geometry and Tool Steel Cr-Mo-V material, the simulation evaluates Von Mises stress, deformation, contact pressure, and fatigue life. The maximum stress on a 12.5 mm billet reaches 1,135.4 MPa, approaching the yield limit of the material, indicating a crack-prone area. Fatigue analysis shows the rollers operating under high-cycle fatigue conditions, where the bottom roller experiences higher stresses and shorter life. The results confirm that billet dimensional variations and dynamic loads significantly affect roller integrity, as well as the importance of predictive maintenance strategies and fatigue-resistant material selection.
