The maximum allowable drying time depends on the efficiency of the drying system used in each case. In practice it has been found that narrow bands whose width max. Such environments are encountered, especially in the petrochemical industry in atmospheres with CO, CH 4 and higher hydrocarbons or in gas mixtures with high carbon activities. Grabke et al. Here twelve different compositions flux baths X have been used in the experiments.

Basismetall base metal. The invention relates to a use of an alloy of aluminum and titanium. Then the narrow bands through still parallel to each other a drying oven in which the flux is dried on the extent that it adheres securely to the narrow bands, but not yet burns.
EPB1 Application of an alloy from aluminium and titanium Google Patents
Use of an alloy of aluminium and titanium as a corrosion-proof coating material with high temperature stability for steel for high temperature service, to provide protection against corrosion in installations with process gases which have a very low oxygen partial pressure "reducing" atmospheres and a carbon activity greater than 1 due to their carbon compounds content.
For the purposes of the invention to be coated "steel flat products" is made of steel produced by hot or cold rolling strips or sheets, and derived blanks and circuit boards. Basically were protective oxide layer is able to process the metal dusting ie a catastrophic carburization to prevent if they could develop an appropriate protective effect on the material surface.
To be thermally post-treated in-line galvannealingthe hot-dip coated steel flat product, to produce a Fe-Zn alloy coating, it has proven advantageous if the melt bath is set such that an IF coating is formed on the steel substrate.

|Metal dusting phenomena were also observed in coal gasification atmospheres, but make no general problem there.
Das der Erfindung zugrundeliegende Problem besteht darin, eine vorteilhafte Verwendung einer Legierung aus Aluminium und Titan aufzufinden.
In practice it has been found that narrow bands whose width max. The process gas, which the alloy is exposed according to this document, has a carbon activity which plays a minor role compared to the corrosive action by the sulfur-containing compounds is not discussed in the text. Die Erfindung basiert auf der Idee, dass eine Schutzschicht, die unter den genannten Bedingungen eine Aufkohlung des Werkstoffs verhindern kann, nur durch extrem stabile Oxide zu erreichen ist.
In the coating system 55 1 tests with supplied as hot-rolled strip steel flat products P have been carried out which have been manufactured from different steels, W1, W2, W3, W4, W5, W6, W7. Effective date :

Here twelve different compositions flux baths X have been used in the experiments. About in the range from 1. Other examples are the failure of waste heat boilers in ammonia plants and facilities of the heat treatment industry. The use of materials for such protective layers as solid material component is ruled out both for cost reasons and for manufacturing and dimensional reasons.
Subsequently, the steel flat products P have passed through the rinsing device 4 consisting of a deionized water rinsing bath V, which has been heated to a temperature TS and which has been completed by the respective portion of the respective flat steel product P within a purge duration tS. There are various types of methods are known which are intended to ensure in each case an optimal adhesion of the coating and optimal performance characteristics of the flat steel product provided with the coating with optimized efficiency.
Following these prescribed for the immersion time and the Fluxmitteltemperatur areas optimum Feinstreinigungseffekt the steel surface is achieved while avoiding an excessive evaporation loss and avoid excessive attack of the grain boundaries on the steel surface.

|Here, too, in practice, hot-dip coating method of the type explained above are used. For the particular effectiveness of the flux used in the invention contributes beyond when its pH is 4 - 4.
Are hot-rolled wide strip is provided with a hot-dip coating, so they can be de-scaled prior to the annealing treatment in a pickling. As Mn or N austenitic microstructure to lower temperatures, which can be used specifically to improve the mechanical material properties.
Then the narrow bands through still parallel to each other a drying oven in which the flux is dried on the extent that it adheres securely to the narrow bands, but not yet burns. Natrium-Ionen Sodium ions.

Due to these outstanding material properties, there is a large application potential for Ni-alloy steel flat products for high and low temperature applications, among others in the automotive vehicle structure, the chemical apparatus, mechanical and plant engineering as well as for decorative elements.

Upon exiting the hot dip station 7 for steel flat products, the thickness of each applied hot dip coating has been set in a known manner by means of a stripping means not shown here. Are hot-rolled wide strip is provided with a hot-dip coating, so they can be de-scaled prior to the annealing treatment in a pickling.
The particular composition of the steels of W1 - W7 is given in Table 1 below. The invention is based on the idea that a protective layer that can under these conditions prevent carbonization of the material can only be achieved by extremely stable oxides.
Lapsed in a contracting state announced via postgrant inform. Grabke et al.

Chlorid-Ionen Chloride ion. With taking place in the continuous run-through hot-dip coating method steel strips can be hot or cold rolled with a width of more than mm, so called "broad tapes", particularly cost-effectively provided with a protective coating. Even with an injury of this layer in operation, a re-healing of injured sites is done because even the low oxygen content of the process environment are able to form these stable oxides again. Louthan Jr et al. DEB4 en. Dadurch reduziert sich die Rauchentwicklung beim Eintauchen des Stahlbands in das Beschichtungsbad, was sich wiederum positiv auf Umwelt- und den Mitarbeiterschutz auswirkt.
