The main difference from TTT diagrams is that continuous cooling does not allow for bainite formation and always results in pearlite. Properties like hardness and strength depend on the formed microstructure constituents like pearlite, bainite, and martensite, which are affected by factors like carbon content, alloying elements, and grain size.

The central position flow field diagram of the 5 typical planes is shown in Fig. 16. In the E-C rotational mode, below the meniscus at 1 m, the molten steel flow is influenced by the curved continuous caster. The central molten steel shows a tendency to flow to the right side, and the flow pattern at the five positions is basically the same.
