Abstract

Bei einem Verfahren zur Zuführung von zumindest einer Manganlegierung zu einem Stahlmaterial bei der Stahlerzeugung, werden der glühenden Masse eines Primärstahles (Q) während dessen Abstiches in eine Gießpfanne (30) die Manganlegierungen in Form von Ferromangan einer bevorzugten Korngröße bis etwa 5 mm mit hohem, mittlerem und niedrigem Kohlenstoffanteil, Mangansilizium mit normalem und niedrigem Kohlenstoffgehalt zugegeben. Die Manganlegierung wird in einem röhrenförmigen, schlauchartig aus Stahlblech geformten Behälter (10) aus einem Werkstoff mit Widerstandsfähigkeit gegen hohe Temperaturen zugeführt und dieser Behälter oder Hülsenstrang (10) mit seinem freien Ende in das Innere der glühenden Masse eingeleitet.In a method for supplying at least one manganese alloy to a steel material in steelmaking, the glowing mass of a primary steel (Q) during its tapping into a ladle (30) the manganese alloys in the form of ferromanganese with a preferred grain size up to about 5 mm with high, medium and low carbon content, normal and low carbon manganese silicon added. The manganese alloy is supplied in a tubular tube-shaped container (10) made of a material having a high temperature resistance, and this container or tube strand (10) is introduced with its free end into the interior of the glowing mass.

Die Stahlblechröhre des Hülsenstranges (10) besteht aus einem Stahlblechstreifen (14), dessen beide Längskanten (16) an einem dichten Falz (18) gleichgerichtet nebeneinander angeordnet sind.The sheet steel tube of the sleeve strand (10) consists of a steel strip (14), the two longitudinal edges (16) on a tight fold (18) rectified are arranged side by side.

Es wird eine Vorrichtung eingesetzt, bei der dem Innenraum (28) einer Gießpfanne (30) für den Primärstahl (Q) der Hülsenstrang (10) zugeordnet ist. Letzterer bildet eine um eine Mittelachse (M) gelegte Wickelrolle (R), von der aus er durch mehrere Paare (24) von Rollen einer Schubeinrichtung (26) geführt und sein freies Ende (11) in die Gießpfanne (30) eingebracht ist.

Figure imgaf001
A device is used in which the inner tube (28) of a ladle (30) for the primary steel (Q) is assigned the sleeve strand (10). The latter forms a winding roll (R) placed around a central axis (M), from which it passes through a plurality of pairs (24) of rollers of a pusher (26) and its free end (11) is introduced into the ladle (30).
