Abstract |
AB |
[DE] Die vorliegende Erfindung betrifft ein Verfahren zum Erzeugen von aus einem metallischen Verbundwerkstoff bestehendem Band (W, W1) oder Blech, umfassend folgende Arbeitsschritte: Erzeugen eines Hohlkörpers aus einem ersten metallischen Werkstoff, Füllen des von dem ersten Werkstoff umgrenzten Innenraums des Hohlkörpers mit sich vom ersten metallischen Werkstoff unterscheidendem schmelzflüssigen metallischen Werkstoff, Erwärmen des gefüllten Körpers (1, 18) auf eine Ziehtemperatur und Warmwalzen des gefüllten Körpers (1, 18) zu Warmband (W, W1). Mit dem erfindungsgemäßen Verfahren lassen sich metallische Verbundwerkstoffe herstellen, die auch höchsten Anforderungen gewachsen sind.
[EN] Production of a strip or sheet made from a metallic composite material comprises: forming a hollow body made from a first metallic material, filling the inner chamber of the hollow body with a second molten metallic material which is different to the first metallic material, heating the filled body to a drawing temperature, and hot rolling the filled body to form a hot strip. Preferred Features: The filled body is deformed into a slab before being hot rolled. The outer layer of the slab if made from the first material and the core layer is made from the second metallic material. The hollow body is produced by casting the first metallic material. The metallic materials are made from steels of different properties, one having a high wear resistance and the other being soft. |
