Abstract - This paper focuses on the investigation of camber and shifting of slabs in the thin slab casting process of steel.
The study begins with a tracking process to monitor the camber of slabs based on their unique slab IDs. Subsequently, data analysis is conducted to examine the relationship between camber and various process parameters. The findings reveal that wedge formation is a significant factor contributing to camber in the thin slab casting process. Further analysis identifies segment water force as the primary cause of the wedge formation. As a result, the study proposes the monitoring of segment force to mitigate camber and shifting issues in thin slab casting. By understanding the underlying causes and implementing appropriate monitoring techniques, this research aims to improve the overall quality and efficiency of the thin slab casting process in the steel industry. Key Words: Quality, Camber, Data, Tracking, Wedge
1. INTRODUCTION The thin slab casting process plays a crucial role in the production of high- quality steel. However, the occurrence of camber and shifting in the cast slabs poses significant challenges to the industry. Camber refers to the curvature or bowing of the slab, while shifting refers to the lateral displacement of the slab during the casting process. These defects not only affect the dimensional accuracy of the slabs but also lead to downstream processing difficulties and reduced product quality. To address these issues, this paper presents a comprehensive investigation into the causes of camber and shifting in thin slab casting of steel. The study begins by implementing a tracking process to monitor the camber of individual slabs based on their unique slab IDs. This enables the collection of data on Camber variations throughout the casting process. Subsequently, a detailed analysis of the collected data is performed to identify the key process parameters that influence camber and shifting. The study reveals that wedge formation is one of the primary factors contributing to camber in thin slab casting. Further analysis delves into the underlying causes of the wedge formation, leading to the discovery that segment water force plays a significant role. Based on these findings, the paper proposes the monitoring of segment force to mitigate camber and shifting issues in thin slab casting. By closely monitoring and controlling the segment water force, it is possible to minimize the formation of wedges and subsequently reduce camber and shifting defects. The objective of this research is to enhance the overall quality and efficiency of the thin slab casting process in the steel industry. By gaining a deeper understanding of the causes of camber and shifting and implementing effective monitoring techniques, manufacturers can optimize their processes, improve product quality, and reduce costly rework and scrap. In the following sections, this paper will delve into the methodology employed for tracking camber, the data analysis techniques used to identify the influence of process parameters, and the findings related to wedge formation and segment water force. The proposed approach for monitoring segment force and its potential impact on reducing camber and shifting defects will also be discussed. Finally, the paper will conclude with recommendations for future research and practical implications for the steel industry.
2. LITERATURE REVIEW The section of this paper provides a comprehensive overview of the existing research and knowledge related to camber and shifting in thin slab casting of steel. Previous studies have identified camber and shifting as common defects in the thin slab casting process, which can have detrimental effects on product quality and downstream processing.
