Description
Verfahren zum Aufbringen von Emailüberzügen auf Eisen Es ist bekannt, daß Emailüberzüge auf niedrig gekohltein Flußstahl von hohem Reinheitsgrad aufgetragen, eine außerordentlich gute Haftfestigkeit besitzen. Weiterhin treten an Stahlblechen häufig festzustellende Oberilächenfehler in Emailüberzügen, wie Fischschuppen, Kupferköpfe usw., bei Verwendung von niedrig gekohltem reinem Stahl (Weicheisen) erheblich seltener auf als bei höher gelzohltem.Process for applying enamel coatings to iron It is known that enamel coatings are applied to low carbon mild steel of a high degree of purity, have an extremely good adhesive strength. Continue to step on steel sheets Surface defects that can often be found in enamel coatings, such as fish scales, copper heads etc., considerably less often when using low-carbon pure steel (soft iron) on than with higher paid.
Ganz besonders gut muß sich daher ein Eisen von höchstem Reinheitsgrad, z. E. Elektrolyteisen, eignen. Der Verwendung von Elektrolyteisen allein steht aber der außerordentlich hohe Preis und ferner die geringe Zugfestigheit des Werkstoffes selbst beim Verformen der zu emaillierenden Gegenstände entgegen.Iron of the highest purity must therefore look particularly good, z. E. Electrolyte iron, are suitable. The use of electrolyte iron alone is available the extraordinarily high price and also the low tensile strength of the material even when deforming the objects to be enamelled.
Erfindungsgemäß werden die Vorteile des reinen Eisens unter Vermeidung der Nachteile dadurch ausgenutzt, daß unlegierte Kohlenstoff stähle oder legierte Stähle mit einer Außenschicht :aus reinem Eisen (Elektrolyteisen) versehen werden, die in bekannter Weise auf Eisen z. B. durch Elektrolyse niedergeschlagen oder durch Plattieren aufgetragen werden kann. Es ist an sich bekannt, die Oberflächen von zu emaillierenden Eisengegenständen mit elektrolytisch oder durch Plattieren aufgebrachten Metallüberzügen oder Legierungen, wie z. B. :aus Nickel, Kobalt o. dgl., zu überziehen. Diesem Bekannten gegenüber unterscheidet sich der Gegenstand der vorliegenden Erfindung dadurch besonders vorteilhaft, daß Schichten von Eisen höchster Reinheit besser :als sonstige Metalle auf der zu veredelnden Eisenoberfläche haften. Außerdem ergeben sich auch noch wirtschaftliche Vorteile.According to the invention, the advantages of pure iron are avoided the disadvantages exploited in that unalloyed carbon steels or alloyed Steels with an outer layer: made of pure iron (electrolyte iron), which in a known manner on iron z. B. precipitated by electrolysis or by Plating can be applied. It is known per se, the surfaces of enamelled iron objects with electrolytic or plating applied Metal coatings or alloys, such as. B.: from nickel, cobalt or the like. To be coated. The subject matter of the present invention differs from this known particularly advantageous because layers of iron of the highest purity are better : Adhere to the iron surface to be refined as other metals. Also surrendered there are also economic advantages.
