초록

This study investigates the restoration and regeneration of damaged quill rods used in roll grinding machines, which are essential in large-scale steel manufacturing processes. Due to continuous wear and tear during operation, these components require effective remanufacturing solutions to restore their functionality. To address this, finite element analysis (FEA) was employed to evaluate the structural integrity and safety of various welding paths used in the restoration process. The results demonstrated that the transverse welding path reduced stress by 6.4% compared to the longitudinal path, making it a more effective method for enhancing the strength of the component. In addition, thermal analysis was conducted to assess the heat impact during the welding process, predicting an increase in hardness of 10.5% in the welded area. The optimized restoration process was successfully applied to quill rod specimens, confirming its effectiveness in extending the service life of roll grinding machines. This remanufacturing technique not only prolongs the lifespan of critical industrial equipment but also offers significant environmental benefits by reducing the need for new parts and lowering manufacturing costs. The findings highlight the importance of sustainable practices in industrial machinery maintenance.
