“…However, mold oscillation will introduce surface defects like oscillation marks and its related subsurface defects due to the periodically oscillation of the mold, which significantly affects the surface quality of slabs. The oscillation marks are usually categorized into two types: hook and depression oscillation marks . Both of them were observed on the shell in Figure through metallographic examinations, among which most of them are depression type.…”

The initial solidification of molten steel in the mold is very important, as it is the origin of the final slab, which associates with the surface defects and determines the final quality of casting slab. In this article, six main topics, including the initial solidification study method, molten steel solidification, mold flux structure, fluid flow, oscillation marks formation, and breakout are reviewed with the purpose to explore the intrinsic mechanism of the complex initial solidification process and its related multi-phase heat transfer phenomena. The results summarized here can provide a foundational understanding of the initial solidification and heat transfer phenomena occurring in the continuous casting mold.
