Description

Verfahren zur Herstellung korrosionsfester Stahlradiatoren Stahlradiatorenglieder wurden bis jetzt aus Kalt-oder Warmbandstahl hergestellt, der, in geeignete Stücke geschnitten, durch Prägen die gewünschte Form erhielt und wonach dann je zwei Platinen mittels elektrischer Rollennahtschweißung zu einem Heizkörperglied vereinigt wurden.Process for the manufacture of corrosion-resistant steel radiators Steel radiator links were made up to now from cold or hot strip steel, which, in suitable pieces cut, got the desired shape by embossing and then two blanks each were combined to form a radiator element by means of electrical roller seam welding.

Im Laufe der Jahre hat sich herausgestellt, daß die Stahlradiatoren, deren Blechstärke meist 1,25 mm betrug, durch Luftsauerstoff- und Kohlensäureangriff, in Verbindung mit anwesendem Wasser oder Wasserdampf, doch einer gewissen Zerstörung unterlagen, vor allen Dingen dann, wenn die Anlagen unsachgemäß gebaut oder gehandhabt wurden.Over the years it has been found that the steel radiators, whose sheet thickness was mostly 1.25 mm, due to atmospheric oxygen and carbonic acid attack, in connection with the presence of water or water vapor, but a certain amount of destruction documents, especially when the systems are improperly built or handled became.

Es hat deshalb auch nicht an Versuchen gefehlt, die Stahlradiatoren durch entsprechende Verfahren korrosionsbeständig zu machen. Das Auftragen irgendwelcher Kunstharz- oder sonstiger überzüge hat sich nicht bewährt, da ein gleichmäßiges und lückenloses Auftragen dieser Überzüge nach Fertigstellung der Glieder unmöglich war. Auch die Verwendung plattierten Materials war einerseits zu teuer und andererseits ließ plattiertes Material weder die Beanspruchung beim Prägen noch beim Schweißen zu.There has therefore been no lack of attempts, the steel radiators to make them corrosion-resistant through appropriate processes. Applying any Synthetic resin or other coatings have not proven effective, as a uniform and complete application of these coatings after completion of the links impossible was. The use of clad material was on the one hand too expensive and on the other hand too expensive Clad material left no stress from embossing or welding to.

Es wurde nun gefunden, daß bei Radiatoren aus Stahlblech, dessen Oberfläche durch Diffusion mittels Metallhalogeniden und Halogenzusatz metallisiert wurde, z. die Korrosionsbeständigkeit durch die mit,der Radiatorenfertigung verbundenen Beanspruchungen nicht beeinflußt wird und 2. die im Heizungsbetrieb gegen die Oberfläche gerichteten Angriffe unwirksam bleiben.It has now been found that in radiators made of sheet steel, the surface was metallized by diffusion using metal halides and the addition of halogen, z. the corrosion resistance due to those associated with the manufacture of radiators Stresses is not influenced and 2. the in heating mode Attacks directed against the surface remain ineffective.
