Description

Zum Auswalzen bestimmter eifiter, vielkäntiger Gußblock Das Hauptpatent betrifft einen verjüngten, vielkantigen Gul,block und eine Isokille zu seiner Erzeugung, dcr°ii Seitenflächen allwechselnd parallel oder zylindrisch und trapezförtnig oder kegelförmig begrenzt sind. Dabei sollen die parallel begrenzten Seiten mit der Sohle des zum Walzen zu verwendenden Kalibers übereinstimmen. Als Beispiel ist im Hauptpatent ein achtkantiger Gußblock beschrieben. d°ss-:n acht Seitenflächen abgewickelt abwechselnd aus vier Rechtecken und vier Trapezen best:hen, wobei die Breite der rechteckiger. Seiten mit der Sohlbreite des Walzkalibers übereinstimmt.For rolling out certain single, many-sided cast block The main patent concerns a tapered, polygonal gul, block and an isokille for its creation, dcr ° ii side surfaces alternately parallel or cylindrical and trapezoidal or are conically limited. The parallel bounded sides should be with the sole of the caliber to be used for rolling. As an example is in the main patent an octagonal cast block described. d ° ss-: n eight side surfaces unwound alternately consist of four rectangles and four trapezoids, the width being the more rectangular. Sides coincides with the bottom width of the rolling pass.

Erfindungsgemäß treten nun an die Stelle ebener Begrenzungsflächen spitzbogenförinige oder andere, nach außen oder nach innen gewölbte Flächen, die mit der Sohle des Walzkalibers übereinstimmen, solange diese Flächen aus parallelen Erzeugenden bestehen oder zylindrisch sind, während die zwischen ihnen liegenden Seitenflächen aus zusammenlaufenden Erzeugenden bestehen oder verjüngt gestaltet sind, so daß als ebene Abwicklung der Umfläche abwechselnd rechteckige und trapezförmige Flächenstücke entstellen.According to the invention, flat boundary surfaces now take the place of them ogive or other surfaces curved outwards or inwards, which with the sole of the rolling pass as long as these surfaces are parallel Generators consist or are cylindrical, while those lying between them Side surfaces consist of converging generators or are tapered are, so that as a flat development of the surrounding area alternately rectangular and trapezoidal Distort areas.

In Abb. i ist ein solcher Gußbl-ock mit spitzbogenförmigen Begrenzungsflächen dargestellt. Die Kokille ist in entsprechender Weise ausgebildet. Dabei verlaufen die Kanten, die die Abschnitterz begrenzen, parallel zueinander, während die Kanten, die die Abschnitte b begrcaren, nicht parallel zueinander verlaufen. Die Breite der Abschnitte a entspricht dabei der Sohle des Walzkalibers. In ähnlicher Weise ist in Abb. 2 der Querschnitt eines Gußblockes dargestellt, bei dem wiederum die Kanten und Erzeugenden, die die Begrenzung der Abschnitte a darstellen, parallel zueinander verlaufen, so daß die Breite der abschnitte a vom oberen bis zum unteren Ende des Gußblockes gleich groß ist. Die Abschnitte b sind dagegen von nicht parallelen Kanten und Erzeugenden begrenzt, und die Breite der Abschnitte b ist infolgedessen am einen Ende des Gußblockes größer als am anderen. Die Kokille muß ebenfalls in entsprechender Weise ausgebildet sein.In Fig. I is such a cast block with ogival boundary surfaces shown. The mold is designed in a corresponding manner. In doing so, run the edges that delimit the segment are parallel to each other, while the edges, which limit the sections b, do not run parallel to one another. The width the section a corresponds to the bottom of the rolling pass. In a similar way is shown in Fig. 2, the cross-section of an ingot, in which again the Edges and generatrices, which represent the delimitation of the sections a, are parallel extend to each other, so that the width of the sections a from the top to the bottom The end of the ingot is the same size. The sections b, however, are of non-parallel Edges and generatrices are limited, and the width of the sections b is as a result larger at one end of the ingot than at the other. The mold must also be in be designed in a corresponding manner.
