1959 Volume 45 Issue 11 Pages 1261-1264
In sequence of the previous report (Tetsu-to-Hagane, Vol. 45, 1959, 1139-1144) concerning surface conditions of the capped ingot, features of core zone in a capped ingot were examined and investigation was made about effect of ingot weight, degree of deoxidation and another factors upon segregation. The following results were obtained:
1. The segregation in core zone of a capped steel ingot was less pronounced than that of a rimmed steel ingot.
2. In a capped ingot, the degree of maximum segregation was increased with the amount of Al added in the ladle, but it was generally less pronounced and the maximum segregated zone was narrower than in a rimmed steel ingot.
