Abstract

In the steel industry, Coil Lifting C-Hooks are critical tools used to lift high-temperature wire rods after the rolling process. The main challenge with this equipment involves repeated mechanical loading and exposure to elevated temperatures, both of which significantly affect structural integrity and operational safety. This research aims to analyze the stress, deformation, fatigue life, and critical failure areas of a C-Hook under thermal-mechanical loading. This study employs the Finite Element Method (FEM) simulation in ANSYS to systematically analyze the impact of repeated loading and high-temperature conditions on structural strength parameters, specifically examining thermal conditions at 170°C and 200°C. The simulation methodology integrates steady-state thermal analysis with static structural analysis to comprehensively evaluate the C Hook’s performance under realistic operating conditions. The results show that repeated loading and increased temperature cause increased deformation (maximum 2.4358 mm at 170°C and maximum 2.425 mm at 200°C), von Mises stress (maximum 140.86 MPa at 170°C and maximum 158.53 MPa at 200°C), and reduced fatigue life (minimum 2,286,900 cycles at 170°C and minimum 1,394,500 cycles at 200°C), as well as a reduced safety factor (minimum 1.0954 at 170°C and minimum 0.973 at 200°C), particularly in the C-Hook curved area. This underscores the importance of C-Hook design that accounts for thermal effects. This research contributes to the existing body of knowledge by combining thermal and structural analysis specific to S275N material under realistic steel industry conditions, offering practical insights for preventing premature equipment failure and enhancing workplace safety in high-temperature lifting operations.
