Description

Das Patent 913 611 betrifft ein Verfahren zum Herstellen von Verbundblechen, insbesondere-durch Walzschweißplattieren, wobei die Berührungsflächen der Platinen, wie an sich bekannt, metallisch blank gemacht, vorzugsweise abgestrahlt sind und das Paket, vorzugsweise nach Verschweißen der Randfugen, erwärmt und schweißplattiert wird. Gekennzeichnet ist dieses Verfahren dadurch, daß zur Erzielung von Verbundblechen mit über die Länge bzw. Breite des Bleches unterschiedliche Stärke der Verbundschichten eine Zwischenplattierschicht zwischen Grund- und Plattierwerkstoff eingefügt wird, die in Einzelplatinen unterteilt ist,- von denen mindestens eine die Zusammensetzung des Grundwerkstoffes und mindestens eine andere die Zusammensetzung des Plattierwerkstoffes aufweist. Die -von der oberen und unteren Platine bedeckten Stoßfugen :der mittleren kleinen. Pliatinen wenden verschweißt. Es besteht weiterhin die Möglichkeit, auch Verbundbleche, die aus mehr als zwei Werkstoffen bestehen, entsprechend herzustellen.Patent 913 611 relates to a method for producing composite sheets, in particular-by roll weld cladding, the contact surfaces of the blanks, as known per se, made metallic bright, preferably blasted and the package, preferably after welding the edge joints, heated and weld clad will. This method is characterized by the fact that to achieve composite sheets with different thicknesses of the composite layers over the length or width of the sheet an intermediate cladding layer is inserted between the base and cladding material, which is divided into individual boards, - of which at least one the composition of the base material and at least one other the composition of the cladding material having. The butt joints covered by the upper and lower plates: the middle one small ones. Pliatines turn welded. There is still the option, too Produce composite sheets that consist of more than two materials accordingly.

Es hat sich als besonders zweckmäßig erwiesen, bei der im Hauptpatent geschützten Herstellung von Verbundblechen mit zonenweise verschiedener Schichtdicke der Einzelschichten-das Verfahren nach Patent 895 558 sinngemäß mit anzuwenden. Dieses Verfahrenbesteht diarin, daß die Platine aus härterem Kohlenstoff- oder Manganstahl mit einer gegenüber dieser um ein gewisses Maß kleineren Platine aus einem weichen Kohlenstoffstahl zusammengelegt und durch Ziehen einer ringsum laufenden Kehlnaht mit der größeren Platine verschweißt, darauf das Platinenpaket erhitzt und gewalzt wird und daß die bei einer Mindesttemperatur von 12oo° C beginnende Walzung zunächst mit ein bis zwei Egalisierstichen bei um 4o bis 5o% verminderter Umfangsgeschwindigkeit, dann bis zu zehn Stichen bei gleicher Geschwindigkeit mit einem Druck von maximal 5 % vorgenommen wird, worauf die restlichen Stiche unter allmählicher Steigerung des Druckes auf die übliche Höhe von 5 bis 2o% und unter allmählicher Steigerung der Walzgeschwindigkeit auf die übliche Größe von 2,5 bis 3,5 m/sec durchgeführt werden.It has proven to be particularly useful in the case of the one in the main patent Protected production of composite sheets with different layer thicknesses in zones of the individual layers - the process according to patent 895 558 should be used accordingly. This method consists in making the board from the harder carbon or manganese steel with a plate made of a soft one, which is smaller than this by a certain amount Carbon steel folded and drawn by drawing a fillet weld all around welded to the larger plate, then the plate package is heated and rolled and that the rolling which begins at a minimum temperature of 1200 ° C initially with one to two equalizing stitches with a circumferential speed reduced by 4o to 5o%, then up to ten stitches at the same speed with a maximum pressure 5% is made, followed by the remaining stitches gradually increasing the pressure to the usual level of 5 to 20% and with a gradual increase the rolling speed to the usual size of 2.5 to 3.5 m / sec will.

In der Abbildung ist als Beispiel ein Paket aus Platinen dargestellt, welches für die Herstellung von Verbundstahlblechen für Blasversatzrohre geeignet ist. Dieses Paket besteht aus den Platinen 1 und 2 des weichen Stahles und den Platinen 3, 4 und 5 des harten Kohlenstoff- bzw. Manganstahles. Die äußeren Fugen 6 sind verschweißt.In the figure, a package of circuit boards is shown as an example, which is suitable for the production of composite steel sheets for blow-off pipes is. This package consists of sinkers 1 and 2 of the soft steel and the sinkers 3, 4 and 5 of hard carbon and manganese steel, respectively. The outer joints 6 are welded.

,Die Fugen sämtlicher Platinen werden verschweißt, insbesondere wird eine ringsum laufende Kehlnaht in die Fuge gelegt, die die kleinere Platine mit den übrigen bildet, und darauf das Paket unter den im Patent 895 55$ angegebenen Walzbedingungen ausgewalzt., The joints of all boards are welded, in particular is a fillet weld running all around was placed in the joint, which the smaller board with forms the rest, and then the package under the $ 895 55 patent Rolling conditions rolled out.
