Verfahren zum Stranggießen von Eisen und StahlProcess for the continuous casting of iron and steel

Patentiert im Gebiet der Bundesrepublik Deutschland vom 16. November 1951 anPatented in the territory of the Federal Republic of Germany on November 16, 1951

Patenterteilung bekanntgemacht am 17. Juli 1958Patent issued July 17, 1958

Beim Stranggießen von Eisen und Stahl in senkrecht stehende, oben und unten offene wassergekühlte Kokillen soll die Gießtemperatur und die Menge des in der Zeiteinheit der Kokille zugeführten Gießgutes möglichst gleichgehalten werden, um Fehler im Strang zu vermeiden. Das Gleichhalten der Gießtemperatur ist aber nur dann möglich, wenn das Gießen unmittelbar aus dem Schmelzofen erfolgt, in dem die Temperatur auf gleicher Höhe gehalten werden kann, oder aus Behältern, die mit einer Heizvorrichtung versehen sind. Verwendet man aber zum Vergießen des Stahles unbeheizte, wenn auch wärmeisolierte Kipppfannen, so muß immer mit einem größeren Temperaturabfall der Schmelze während des Vergießens gerechnet werden.During the continuous casting of iron and steel in vertical, water-cooled ones that are open at the top and bottom Chill molds should be the casting temperature and the amount of cast material supplied to the chill mold in the unit of time are kept the same as possible in order to avoid errors in the line. Maintaining the same casting temperature but is only possible if the casting takes place directly from the melting furnace in which the temperature is set can be kept at the same level, or from containers provided with a heating device are. But if you use unheated, albeit thermally insulated tilting pans to cast the steel, so A greater temperature drop in the melt during casting must always be expected.

Es wurde festgestellt, daß die mögliche Größtabsenkgeschwindigkeit des Stranges von der jeweiligen Gießtemperatur der Schmelze abhängig ist, und zwar steigt sie mit fallender Gießtemperatur an. Als Beispiel sei angegeben, daß beim Vergießen eines Chrom-Molybdän-Stahles zum Strang von 130 mm Durchmesser die Absenkgeschwindigkeit von anfänglich 0,7 m/min bei 16000C mit sinkender Temperatur auf 1,15 m/min bei 15100C gesteigert werden konnte.It was found that the maximum possible lowering speed of the strand depends on the particular casting temperature of the melt, and that it increases as the casting temperature falls. As an example, given that a chromium-molybdenum steel for the strand of 130 mm diameter the lowering speed from an initial 0.7 m / min at 1600 0 C with decreasing temperature to 1.15 m / min increased at 1510 0 C in casting could.
