| Abstract: | The forming mechanism of slag skin was studied during electroslag casting. The results of chemical (analysis), petrographic analysis of several sublayers of the slag skin showed that the "ring shaped miniature slag pool" was formed around the upper edge of the solidified ingot during the ESR process in ingot retracting. The shape and stability of the "miniature slag pool" affected the thickness of slag skin and the ESR ingot surface quality. It was also thought that the better superficial quality of steel ingot would be obtained in the slag, which was high under-cooling degree and low smelting point, was used. |
