aus einem ummantelten Werkblock hergestellt. Der innere Block dient also als Dorn. Nach dem Erkalten wird das Überzugsrohr von der Stange gelöst und abgezogen, so dass beide Teile für sich verwendet werden können. Zweckmässig wird zwischen Mantel und Werkblock eine Isolierung, z. B. Oxydsehieht, Aluminiumbronze usw. vorgesehen, um das spätere Lösen zu erleichtern.
Das erfindungsgemässe Verfahren kann auch Anwendung finden, um Rohre als Schutzmantel um Stangen zu legen, indem der Mantel auf einen massiven Kernblock aufgeschoben und das Ganze ohne Dom wie auf einer Strangpresse ausgepresst wird.
Die Fig. 4 a-c zeigen das entsprechende Vor-bzw. Fertigprodukt.
Will man besonders festhaftende Überzüge auf Stangen oder Röhren erzielen, so empfiehlt es sich, die Berührungsflächen von Mantel und Werkblock metallisch rein auszuführen.
PATENT-ANSPRÜCHE :
1. Verfahren zum Strangpressen von erhitzten, aus mehreren Schichten bestehenden Voll-oder Hohlblöcken, dadurch gekennzeichnet, dass der Kern (k) des Blockes aus Eisen oder einer Eisenlegierung und der äussere und/oder innere festhaftende Überzug (m, s) des Blockes aus einer andern Eisenart oder Eisenlegierung oder aus einer Legierung sonstiger Metalle von annähernd der Presstemperatur des Eisens besteht.

made from a covered work block. The inner block thus serves as a mandrel. After cooling, the cover tube is released from the rod and pulled off so that both parts can be used separately. It is advisable to use insulation between the jacket and the work block, e.g. B. oxide, aluminum bronze, etc. provided in order to facilitate later loosening.
The method according to the invention can also be used to place pipes as a protective jacket around bars by pushing the jacket onto a solid core block and pressing the whole thing without a dome like on an extrusion press.
FIGS. 4 a-c show the corresponding before or. Finished product.
If you want to achieve particularly firmly adhering coatings on rods or tubes, it is advisable to make the contact surfaces of jacket and work block metallic clean.
PATENT CLAIMS:
1. A method for extruding heated solid or hollow blocks consisting of several layers, characterized in that the core (k) of the block is made of iron or an iron alloy and the outer and / or inner firmly adhering coating (m, s) of the block Another type of iron or iron alloy or an alloy of other metals at approximately the pressing temperature of iron.
