A method for the direct production of steel with low-sulfur core and controlled sulphur content in the edge zone

摘要

the invention relates to a method for the continuous casting of steel, in which the molten steel from a tundish (tundish) by a gieu00dfrohr in the cooled mould pouring and the generated stahlstrang in its cross-section has a different chemical composition aufweis t.$a continuous stahlstru00e4nge, to create in their surface area adjacent to a much higher concentration in the continuous input legierungsmittel) in the core of the same strand, is proposedlegierungsmittel in the form of wire continuously and geschwindigkeitsgesteuert from the top of the mould are introduced and the legierungsmittel near the stahlbadspiegels maximum at a depth, the depth of immersion of the gieu00dftauchrohres is aufzuschmelzen.
