A high quality homogeneous sound killed steel ingot having a reduced quantity of negative segregation and of inverted V-shaped segregation zones is produced by adding a stirring agent to the molten steel during the solidification process and at a time period between the period during which the negative segregation section and the inverted V-shaped segregation zones are formed, and the period during which the V-shaped segregation zone is formed wherein the stirring agent is preferably an element, alloy, compound or mixture thereof of an element selected from the group of elements of Groups I-a or II-a of the Periodic Table or zinc, or the halides of an element of Groups I-b, III-b, IV-a, IV-b, VI-a, VII-a, or VIII.
