The Influence of the Melting and Casting Parameters on the Surface Quality of Deep-Drawn Steel Coils

Industrial production today increasingly prioritizes sustainability, emphasizing not only efficiency but also minimizing environmental and social impacts. Quality control is key in steel production. The continuous casting process is crucial, as early defect detection can lower costs and prevent unnecessary material use, thereby conserving energy and raw materials. Eliminating defects early reduces the need for costly reworking, saving resources and reducing equipment wear. Additionally, this defect prevention supports efficiency in later steps, like rolling, benefiting overall energy and material consumption. During this research, we identified several parameters whose influence we analyzed on the surface quality of deep-drawn steel. The research confirmed that, for example, the casting speed has a significant influence on the occurrence of surface defects, while, for example, the final bubbling had no statistically significant effect on the surface quality. From a sustainability perspective, monitoring and optimizing key production parameters, like the casting speed, is essential, as improper speeds can cause surface defects that risk the functionality of the final products. By optimizing these parameters, it is possible not only to reduce the risk of product failure but also to contribute to the long-term sustainability of the entire production process, reducing waste and fostering a more considerate approach to natural resources.
