"Stranggießrolle mit korrosionsbeständiger, abriebfester Schutzschicht^"Continuous casting roll with corrosion-resistant, abrasion-resistant protective layer ^

Die Erfindung betrifft eine Stranggießrolle mit korrosionsbeständiger, abriebfester, aus mehreren Lagen bestehender Schutzschicht. . 'The invention relates to a continuous casting roll with corrosion-resistant, abrasion-resistant protective layer consisting of several layers. . '

Es ist bekannt, den"Grundwerkstoff einer Stranggießrolle durch Aufspritzen einer Schutzschicht ^beständiger gegen iSpannungsrisse zu machen.It is known that the base material of a continuous casting roll can be made more resistant to stress cracks by spraying on a protective layer.

Außerdem ist es TDekannt, die auf äen Grundwerkstoff aufgespritzte Schutzschicht zu sintern, um eine höhere Haftfestigkeit derselben zu erzielen. ■ "It is also known that it is sprayed onto the base material To sinter protective layer in order to achieve a higher adhesive strength of the same. ■ "

Im Gegensatz zu den gespritzten Schichten, die aus einem Gemischaus Metall und Metalloxyden -bestehen., sind die gesinteren Schichten rein metallisch.In contrast to the sprayed layers, which consist of a mixture of Metal and metal oxides exist, are the sintered layers purely metallic.

Fei den bekannten mit'vorstenend besciiriebenen Schutzschichten versehenen Stranggleßröilen 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.For the well-known protective layers described above "" Bending stresses cause cracks to occur on 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 eliminated.

Bie erfindungsgemäße iStranggießrolle verhindert durch die duktile Zwischenschicht auch bei starken Biegebeanspruchungen ein Eindringen korrosiver Medien in den Grundwerkstoff*The continuous casting roll according to the invention prevented by the ductile Intermediate layer a penetration of corrosive media into the base material even with strong bending loads *

Hierdurch wird eine Stranggießrolle erzielt, die sowohl korrosionsbeständig ist als auch eine verschleißfeste Oberfläche aufweist. Auch bei Auftreten von Spannungsrissen an der Außenschicht werden diese auf den Dickenbereich der Außenschicht begrenzt.This results in a continuous casting roll that is both corrosion-resistant is as well as having a wear-resistant surface. Even if stress cracks appear on the outer layer these are limited to the thickness range of the outer layer.
