WebMay 3, 2024 · Macro-segregation in continuous casting of the slab is classified into three main categories as centreline segregation, ‘A’ and ‘V’ segregation, and inter-columnar macro-segregation [ 2 ]. Centreline segregation is observed at the centre of the slab due to the rejection of solute enriched liquid towards the end of solidification.
WebContinuous casting, also known as strand casting, is the process where a metal is heated until it liquefies. The molten metal is then allowed to solidify until it becomes a semi-finished slab that is later rolled in the finishing mill. It is used to cast metals of uninterrupted lengths.
