Carbon segregation map - 3.3 t ingot - Ingot defects


Figure 1: Carbon segregation map: (a) sulfur-print of the experimental ingot, (b) simulation result.

Defect name: Segregation
Record No.: 3358
Type of defect (Internal/Surface): Internal
Defect classification: Ingot defects
Steel name: Steel
Steel composition in weight %: 0.49% C, 0.23% Si, 0.51% Mn, 0.03% P, 0.03% S.
Note:  Comparison between the sulfurprint of the experimental ingot and numerical prediction is shown in Fig. 1. For the sulfur-print, dark color corresponds to positive segregation, and light color corresponds to negative segregation. Some black discontinuous lines, close to the ingot surfaces, are called A-segregates in which the solute is enriched. We can note that the general segregation pattern in the experiment is well reproduced in the simulation, such as top positive segregation, bottom negative segregation, and A-segregates.
