Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Optimierung der Qualität, von in mindestens einer Gießmaschine mit Kokille (2) endlos gießbaren Gießsträngen (1) mit runden oder annähernd runden Querschnitten bzw. Querschnittsbereichen, im Bereich der Soft-Reduktion (Resterstarrung). Hierzu werden die Gießstränge (1) unterhalb der Kokille (2) im Bereich der Resterstarrung in wenigstens einer Reduzierebene durch anstellbare Rollen (4, 5) zur Verbesserung der Innenqualität reduzierend verformt. In einem weiteren Schritt kann der runde oder annähernd runde Gießquerschnitt durch beidseitig anstellbare und um 90° zur Reduzierebene versetzte Rollen (4, 5) um einen Betrag zwischen 5 und 60 % der Hauptreduzierung im Bereich der Resterstarrung (8) verformt werden, um die Innenqualität durch eine weitere Kernverdichtung zu erhöhen.

The invention relates to a method and a device for optimizing the quality of casting strands (1) which can be cast continuously in at least one casting machine with a mold (2) with round or approximately round cross sections or cross sectional areas, in the area of soft reduction (residual solidification). For this purpose, the casting strands (1) below the mold (2) are deformed in the area of residual solidification in at least one reduction level by adjustable rollers (4, 5) to improve the internal quality. In a further step, the round or approximately round casting cross section can be deformed by rollers (4, 5) that can be adjusted on both sides and are offset by 90 ° to the reduction level by an amount between 5 and 60% of the main reduction in the area of residual solidification (8) in order to improve the internal quality by increasing core compaction.
