This study addresses the different types of internal and surface cracks that can continuously form during steel casting. For each crack type, the operating and metallurgical factors known to influence crack formation are evaluated due to the high temperature mechanical properties of steel and knowledge of the stresses generated in the solidifying shell. The significance of two low ductility zones in steel is shown by this process. One area is above 1340 °C and all internal cracks and longitudinal surface cracks can be formed. The other regions are between 700 and 9000 °C and are associated with the presence of soluble aluminum, niobium and vanadium. In slabs, lateral surface cracks can be connected to the other latter region. This expertise, combined with an understanding of the stresses produced by continuous casting, makes it possible to propose mechanisms of crack formation and relate them to operational and metallurgical variables.
