Description

Aus der DE-OS 26 36 199 ist ein Verfahren zur Herstellung von vergüteten Rollen für Stranggießanlagen bekannt, wobei auf den Rollenkern ein Nickel- und Chrom-haltiger Werkstoff aufgespritzt und anschließend gesinter» wird. Hierbei bildet sich zwar eine Diffusionsschicht also eine Übergangsschicht aber keine definierte Zwischenschicht im Sinne der Erfindung.From DE-OS 26 36 199 a method for the production of tempered rolls for continuous casting plants is known, with a nickel- and chromium-containing material being sprayed onto the roll core and then sintered ». In this case, a diffusion layer is formed, that is to say a transition layer, but none defined intermediate layer within the meaning of the invention.

Bei den mit vorstehend beschriebenen Schutzschichten versehenen Stranggießrollen treten bei Biegespannungen Risse an den Kristallen auf, die während des Betriebes ein Eindringen von korrosiven Medien ermöglichen. Auf diese Weise wird die Haftung der Schutzschicht am Grundwerkstoff durch Korrosion desselben beseitigt.
Bei Stranggießkokillen ist es bekannt auf die aus Kupfer bestehende Kokillenwand eine erste Nickel/Kobalt-haltige Schicht und darauf eine Nickel/Kobalt/ Phosphor-haltige Schicht elektronisch aufzubringen (US-PS40 37 646).In the case of the continuous casting rolls provided with the protective layers described above, when bending stresses, cracks occur in the crystals, which allow the penetration of corrosive media during operation. In this way, the adhesion of the protective layer to the base material due to corrosion of the same is eliminated.
In the case of continuous casting molds, it is known to electronically apply a first nickel / cobalt-containing layer and then a nickel / cobalt / phosphorus-containing layer to the mold wall made of copper (US Pat. No. 4,037,646).

Die zweite — also zum Kokilleninnenraum gewandteThe second - that is, facing the interior of the mold

ίο — Seite weist eine große Härte auf und "Ment als Verschleißschicht. Die erste Schicht ist wesentlich duktiler und bewirkt dadurch einen Spannungsübergang zwischen der nicht duktilen zweiten Schicht und der sehr duktilen Kupferwand. Die Korrosionsbeständigkeitίο - side has a great hardness and "ment as Wear layer. The first layer is much more ductile and thus causes a stress transition between the non-ductile second layer and the very ductile copper wall. The corrosion resistance

'5 ist bei allen drei Werkstoffen vorhanden, so daß bei der Entstehung von Rissen in der Verschleißschicht die erste Schicht oder die Kokiilenwand aus Kupfer nicht angegriffen werden.'5 is present in all three materials, so that in the Formation of cracks in the wear layer the first layer or the mold wall made of copper not to be attacked.

In der Zeichnung ist eine erfindungsgemäß mit einer Mehrlagenschutzschicht versehene kühlbare Stranggießrolle schematisch dargestellt.The drawing shows a coolable continuous casting roll provided according to the invention with a multilayer protective layer shown schematically.

In dieser Zeichnung ist der Grundwerkstoff 1 der Stranggießrolle mit nicht näher bezeichneten Kühlkanälen mit einer auf der duktilen Zwischenschicht 3 aufgesinterten Außenschicht 2 versehen.In this drawing, the base material 1 is the continuous casting roll with unspecified cooling channels provided with an outer layer 2 sintered onto the ductile intermediate layer 3.

Die in der Zeichnung dargestellten Kühlkanäle werden nicht beschrieben.The cooling channels shown in the drawing are not described.
