Zusammenfassung:	A process of producing steel ingots having a steel composition at the skin which differs from that at the heart comprises tapping incompletely killed steel from a tapping ladle into an ingot mould, adding a deoxidizing agent to the steel in the mould, intensively mixing the steel for a period in minutes equal to at least half the height of the ingot in meters and decanting the inclusions in the steel, both the intensive mixing and decant taking place during the basaltic crystallization phase.
