- •
A dendritic model was used to predict macrosegregation of an industrial ingot.
- •
Secondary dendrite arm spacing (SDAS) plays an important role on final characteristic of segregation.
- •
The quasi A-segregation is mainly caused by the instability of interdendritc flow.
- •
Ingot size effect plays more important role than thermal conduction in the formation of the negative segregation zone under hot top.
