Abstract

Process for the continuous casting of metals comprises profiling two rolls that rotate against each other having lateral insulation so that the rod after partial or complete solidification has one or more profile cross-sections, e.g. round, angular, U-steel, double T-steel, or profiled band surface, e.g. tear or perforated sheet.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum kontinuierlichen endlosen Gießen von Metallen insbesondere auch Stahl, wobei aus einem Metallschmelzbehälter über ein Tauchrohr die Schmelze in eine mitlaufende aus zwei Walzen mit Seitendämmung bestehende Gießkokille gegossen wird und der teilweise oder vollständig erstarrte Strang aus dem Gießwalzspalt zwischen den Walzen herausgezogen wird. Dieser Strang kann entweder direkt einer Unterteil­ anlage zum Ablängen auf Transport- oder Verkaufslänge oder vorher einer Profilier­ walzanlage zugeführt werden.The invention relates to a method and a device for continuous endless casting of metals especially steel, being from a Metal melt container via an immersion tube to melt the melt into a moving one two casters with side insulation existing casting mold is poured and the partially or completely solidified strand from the casting roll gap between the Rollers is pulled out. This strand can either be directly a lower part System for cutting to length for transport or sales or a profiling beforehand Rolling system are fed.

Zweiwalzengießanlagen nach dem Bessemerprinzip, Bild 1, sind bekannt zum Gießen von Band, also Rechteckquerschnitten mit kleiner Dicke und großer Breite. Profile werden aus großen Gießquerschnitten in mehreren hintereinander erfolgen­ den Walzstichen mit Querschnittsabnahmen und Änderung des Profils im Warmwalz­ prozeß oder durch Kaltumformen in mehreren hintereinander erfolgenden Profilier­ stichen ohne Querschnittsabnahme hergestellt.Two-roll casting machines based on the Bessemer principle, Figure 1, are known for casting strip, i.e. rectangular cross-sections with a small thickness and a large width. Profiles are made from large casting cross-sections in several successive roll passes with cross-sectional decreases and profile changes in the hot rolling process or by cold forming in several successive profiling passes without cross-sectional reduction.

Beim Warmwalzen nach heutigem Stand der Technik erfolgt eine für das Erreichen der gewünschten Eigenschaften des Fertigprofils unnötig hohe Querschnittsabnahme und Walzarbeit, was sich auch in einem unnötig hohen Aufwand der Investitionskosten der Erzeugungsanlagen und deren Betriebskosten niederschlägt. In hot rolling according to the current state of the art, one takes place for the achievement the desired properties of the finished profile unnecessarily high Cross-sectional decrease and rolling work, which also results in an unnecessarily high Effort of the investment costs of the generating plants and their operating costs precipitates.  

Wie beim Bandgießen nach Bessemer soll die Walzarbeit auch für die Erzeugung von Profilen durch das erfindungsgemäße Gießen der endabmessungsnahen oder endabmessungsfertigen Profile, die Höhe der Investitionskosten der Erzeugungsan­ lagen und die Betriebskosten minimiert werden.As with strip casting according to Bessemer, the rolling work should also be used for production of profiles by the inventive casting of near-net or ready-made profiles, the amount of investment costs of the generation and operating costs are minimized.

Aufgabe der Erfindung ist es, den Erzeugungsweg von Profilen wesentlich zu ver­ kürzen und damit Anlagen zu schaffen, die schon bei kleinen Erzeugungsmengen wirtschaftlich sind und die Investitionskosten und Betriebskosten wesentlich senken.The object of the invention is to significantly ver the production path of profiles shorten and thus create plants that already with small production quantities are economical and significantly reduce investment and operating costs.

Bild 2 zeigt die erfindungsgemäße Ausführung der Wälzen, zwischen denen gegossen wird und der Strang erstarrt:
Beispiel 1 zur Erzeugung von einem profilierten Band mit periodisch wiederkehren­ den Rundquerschnitten, die nach dem Gießen durch Längsteilen in einzelne Rund­ stäbe aufgeteilt werden können, Beispiel 2 zur Erzeugung von Winkelprofilen, Beispiel 3 zur Erzeugung von U-Stahl, Beispiel 4 zur Erzeugung von Doppel-T-Stahl, Beispiel 5 und 6 zur Erzeugung von Lochblechen und Beispiel 7 zur Erzeugung von einseitigen Tränenblechen. Figure 2 shows the design of the rollers according to the invention, between which is poured and the strand solidifies:
Example 1 for the production of a profiled strip with periodic recurrence of the round cross-sections which can be divided into individual round bars after casting by slitting, Example 2 for the production of angle profiles, Example 3 for the production of U-steel, Example 4 for the production of double -T steel, Examples 5 and 6 for the production of perforated plates and Example 7 for the production of one-sided tear plates.

Vorteile der Erfindung sind geringere Investitions- und Betriebskosten durch Verkürzung und Vereinfachung des Erzeugungsweges, die die wirtschaftliche Erzeugung auch kleinerer Mengen ermöglicht.Advantages of the invention are lower investment and operating costs Shortening and simplification of the production route, the economic Generation of smaller quantities is also possible.
