Investigating temperature stresses in slag pots is crucial for optimizing metallurgical processes, reducing metal losses, and improving efficiency. Slag pots experience significant thermal loads, leading to cracks, defects, and reduced lifespan. These failures are primarily caused by temperature gradients within the pot, requiring accurate mathematical models that account for temperature-dependent material properties. Numerical modeling enhances the prediction of material behavior, reducing operational costs. Developing such models is essential for efficient slag handling. Research has identified temperature and thermal stress fields, revealing the mechanism of microcrack formation in pot walls due to hot slag exposure. Materials like steel 30KhML can significantly enhance the slag pots' performance and lifespan. Optimizing slag pot design and material selection reduces operating costs and enhances safety.
