Abstract

Die Erfindung betrifft einen Eintauchausguß zum Gießen von flussigen Metallen, insbesondere flüssigem Eisen oder Stahl, enthaltend Zirkoniumoxid, kohlenstofhaltiges Mat­ erial, Bornitrid und übliche Zusätze. The invention relates to an immersion nozzle for casting of liquid metals, especially liquid iron or Steel containing zirconium oxide, carbon-containing mat erial, boron nitride and usual additives.

Der erfindungsgemäße Eintauchausguß ist dadurch gekennzeichnet, daß zumindest der Eintauchbereich des Eintauchausgusses aus: The immersion nozzle according to the invention is thereby characterized in that at least the immersion area of the Immersion spout from:

a) 5 bis 15 Gew.-% kohlenstoffhaltigem Material a) 5 to 15 wt .-% carbonaceous material

b) 2 bis 12 Gew-% Bornitrid b) 2 to 12% by weight boron nitride

c) 0 bis 6 Gew-% üblichen Zusätzen c) 0 to 6% by weight of conventional additives

d) als Rest auf 100 Gew.-% gesintertem, porosem teilsta­ bilisiertem Zirkoniumoxid.
besteht. d) the remainder to 100% by weight of sintered, porous, partially stabilized zirconium oxide.
consists.

Der erfindungsgemäße Eintauchausguß weist den Vor­ teil einer hohen Verschleißfestigkeit und ausreichender Tem­ peraturwechselbeständigkeit bei geringer Neigung zum Zuschmieren auf, so daß insbesondere auch dünnwandige Eintauchausgüsse mit geringer lichter Weite hergestellt wer­ den können. The immersion nozzle according to the invention has the front part of a high wear resistance and sufficient temperature Resistance to temperature changes with a low tendency to Smear on, so that especially thin-walled Immersion spouts with a small internal clearance are produced that can.
