Abstract
Description
Stranggießkokille F i g. 1 in herkömmlicher Weise an der Berührungsfläche zwischen Kokillenwand und Gußstrang abgeflacht, so daß sich bei der Stranggießkokille F i g. 1 eine Berührungsbreite von 2,5 mm je Steg ergibt.Continuous casting mold F i g. 1 in a conventional manner at the contact surface between the mold wall and the cast strand flattened so that in the continuous casting mold F i g. 1 results in a contact width of 2.5 mm per web.
Demgegenüber ist die erfindungsgemäße Stranggießkokille an den Berührungsflächen zugespitzt, wie es in F i g. 2a dargestellt ist. Der direkte Kühlteil 3 besteht aus den Kühlmittelöffnungen 4 und den Stegen 5, die an der Berührungsfläche zum Gußstrang 6 hin zugespitzt sind. Die Breite der Auflagefläche bei der Stranggießkokille F i g. 2a beträgt 0,1 mm.In contrast, the continuous casting mold according to the invention is pointed at the contact surfaces, as shown in FIG F i g. 2a is shown. The direct cooling part 3 consists of the coolant openings 4 and the webs 5, which at the contact surface to the cast strand 6 are pointed out. The width of the contact surface of the continuous casting mold F i g. 2a is 0.1 mm.
Mit beiden Stranggießkokillen wurde ein Strangband der Dicke 12 mm und der Breite 750 mm bei ansonsten gleichen Gießbedingungen (Metalltemperatur, Gießgeschwindigkeit, Kühlmittelmenge) aus der Legierung AlMg 5 gegossen.A strand strip 12 mm thick and 750 mm wide was otherwise used with both continuous casting molds same casting conditions (metal temperature, casting speed, amount of coolant) from the alloy AlMg 5 cast.
Das Strangband aus der Stranggießkokille F i g. 1 zeigte sporadische Längsrisse und unregelmäßige Gußstrukturen, die sich auf der Oberfläche abzeichnen (Foto 2). Das Strangband aus der Stranggießkokille F i g. 2 (Foto 3) war rißfrei und zeigte eine gleichmäßige Gußstruktur. The strand from the continuous casting mold F i g. 1 showed sporadic longitudinal cracks and irregular cast structures, which stand out on the surface (photo 2). The strand from the continuous casting mold F i g. 2 (Photo 3) was free of cracks and showed a uniform cast structure.
In Fig.2 sind zwei alternative Stegformen dargestellt. Die bevorzugte Ausführungsform nach Fig.2a weist spitze Stegenden auf, die eine Auflagebreite von weniger als 0,1 mm besitzt. Diese Stegform gestattet es, besonders schwer gießbare AlMgSi-Legierungen rißfrei zu gießen.Two alternative web shapes are shown in FIG. The preferred embodiment according to FIG. 2a has pointed web ends which have a support width of is less than 0.1 mm. This bar shape allows AlMgSi alloys that are particularly difficult to cast to be free of cracks to pour.
In Fig.2b sind abgerundete Stegenden dargestellt, deren Krümmungsradius etwa der Hälfte der Stegbreite entspricht. Diese Stegform ist besonders verschleißarm und daher für hochfeste Legierungen geeignet, insbesondere in Verbindung mit einer Hartverchromung oder Vernickelung.In Fig. 2b rounded web ends are shown, whose radius of curvature corresponds to about half the web width. This bar shape is particularly wear-resistant and therefore suitable for high-strength alloys, especially in connection with hard chrome plating or nickel plating.

In the case of the continuous casting dies, usually made of copper, a negative pressure casting mold can be achieved within the injection zones in that the mold that is in contact with the cooling water 50 surface of the cast strip is in contact with the surface of the cast strip and is thus in contact with it Freezing of the surfaces is prevented with a 20 to 40 μm thick hard chrome layer tape and, on the other hand, suction of the nickel layer or a layer of nickel can be coated.

Diese sind bei derThe continuous casting of crack-free strips made of high-alloyed alloy reduces and thereby the service life of the mold, especially aluminum materials, sets an extremely high level of compliance with the increase, which is difficult to achieve in practice, especially when casting high-strength and thus hard strips. This is of particular importance in view of the inventive casting parameters, such as metal temperature, the direct amount of coolant and the lubricant metering in advance, and on the other hand the cooled mold section. In addition, the bandwidth that can be generated and the casting capacity have also shown that the tendency to stick is only limited in speed. In addition, it has been shown indirectly that the strip surface is reduced by hard chrome plating of materials such as AlMg 5, irregular or nickel plating, especially in the case of high-alloy-cooled mold parts,
