Maschinenfabrik Meer Akt.-Ges. in M. Gladbach Werkstoff für Kokillen zur Herstellung von StahlblöckenMaschinenfabrik Meer Akt.-Ges. in M. Gladbach Material for molds for the production of steel blocks

Patentiert im Deutschen Reiche vom 10. April 1932 abPatented in the German Empire on April 10, 1932

Die Erfindung betrifft eine Blockkokille zur Herstellung von Stahlblöcken.The invention relates to a block mold for the production of steel blocks.

Der Werkstoff derartiger Kokillen bestand bisher aus gewöhnlichem Gußeisen. Es hat sich gezeigt, daß dieses sehr schnell abgenutzt wird.The material of such molds has hitherto consisted of ordinary cast iron. It has it has been shown that this wears out very quickly.

Die Erfindung besteht in der Verwendung eines an sich bekannten Gußeisens mit 0,1 bis o,S °/0 Molybdän je nach der Wandstärke der Kokille. Das Molybdän wird in Form von 6o°/0igem Ferromolybdän dem flüssigen Eisen in der Gießpfanne zugesetzt. Der Kohlenstoffgehalt der Gußeisenlegierung beträgt ebenfalls je nach der Wandstärke der Kokille vorzugsweise 3 bis 4 °/0. Die Gehalte der sonstigen Legierungsbestandteile (Mn, Si, P und S) sind die für Gußeisen üblichen. Die Haltbarkeit einer derartigen Kokille .ist mindestens doppelt so groß wie die der bekannten. The invention consists in the use of a known cast iron with from 0.1 to o, S ° / 0 molybdenum, depending on the wall thickness of the mold. The molybdenum is added in the form of 6o ° / 0 sodium ferromolybdenum the liquid iron in the ladle. The carbon content of the cast iron alloy is also preferably from 3 to 4 ° / 0 depending on the wall thickness of the mold. The contents of the other alloy components (Mn, Si, P and S) are those usual for cast iron. The durability of such a mold is at least twice that of the known ones.
