Abstract

Die Erfindung betrifft ein Verfahren zum kontinuierlichen Gießwalzen metallischer Flachprodukte, insbesondere aus Stahl durch Eingießen der Schmelze in eine Stranggießkokille, Abziehen des über den Gießquerschnitt teilweise erstarrten Stranges mittels Rollenpaare, Verformen des Stranges mindestens im Bereich seiner Erstarrungsstrecke. Um ein Verfahren anzugeben, mit dem bereits mit der Stranggießanlage ein Produkt mit hohem Anteil an Walzgefüge zur Verfügung gestellt wird, das mit der die Gießanlage verlassenden Dickenabmessung coilfähig ist, wird vorgeschlagen, daß in der Stranggießkokille ein Flachprodukt mit einer Dicke von 50 bis 100 mm erzeugt wird, das so erzeugte Flachprodukt innerhalb der Erstarrungsstrecke mindestens 10% bis zu 70% in seiner Dicke reduziert wird und mittels der Rollenpaare im durcherstarrten Bereich des Flachproduktes eine weitere Reduktion der Dicke um mindestens 30% vorgenommen wird. The invention relates to a method for continuous Casting rolls of flat metal products, in particular made of steel Pouring the melt into a continuous casting mold, pulling the over the Casting cross section of partially solidified strand by means of pairs of rollers, Deformation of the strand at least in the area of its solidification path. To specify a process that is already using the continuous caster Product with a high proportion of roll structure is made available with which the thickness dimension leaving the casting plant is capable of being coiled proposed that in the continuous casting mold a flat product with a Thickness of 50 to 100 mm is generated, the flat product thus produced within the solidification distance at least 10% up to 70% in its Thickness is reduced and by means of the pairs of rollers in the solidified Area of the flat product a further reduction in thickness by at least 30% is made.
