Patent number: 12017274Abstract: A method for manufacturing a steel ingot in a casting arrangement employs a vacuum vessel; an ingot mold arranged within the vacuum vessel, and a stirrer arranged to stir liquid steel in the ingot mold. The method employs the following steps: providing a liquid steel melt; filling the ingot mold with the liquid steel melt; applying a reduced pressure within the vacuum vessel; allowing the liquid steel melt to solidify into an ingot; and allowing the liquid steel melt to solidify under stirring within the ingot mold at a reduced pressure during solidification of the steel melt. The liquid steel melt includes a predetermined amount of carbon and; incidental impurity elements in the form of oxides. During stirring, the oxides are reduced by carbothermic reaction in which oxygen in the oxides and carbon in the steel melt form carbon-monoxide.Type: GrantFiled: March 20, 2020Date of Patent: June 25, 2024Assignee: OVAKO SWEDEN ABInventors: Jan-Erik Andersson, Joakim Fagerlund
