- printing plate support which have been made of an aluminum alloy with a correspondingly low Aluminiumcarbidrent allow the use of gas-tight coatings, since the blistering is extremely low. It is believed that the slightest trace of aluminum carbide (Al 4 C 3 ) and its reaction with moisture to form methane gas causes bubbling under the gas tight coatings. Surprisingly, it has been found that in particular the composition of the aluminum alloy of the printing plate support plays an important role in the blistering, although it was previously assumed that it is essentially one of the Surface of the printing plate carrier is tried phenomenon. Previous aluminum alloys have therefore not been optimized for the lowest possible aluminum carbide content.
- the aluminum carbide content of the aluminum alloy according to the invention is adjusted to less than 1 ppm, so that blistering is prevented in the case of gas-tight coating of the printing plate carrier.
- the further composition of the aluminum alloy corresponds to an aluminum alloy of the type AA1xxx, AA3xxx, AA8xxx, preferably AA1050, or AA3103.
- the aluminum alloys mentioned it is known that they at least partially meet the requirements for lithographic printing plate supports and have hitherto been used for their production.

- This aluminum alloy is particularly well suited for the production of lithographic printing plate supports due to its balanced properties in terms of mechanical stability, chemical and electrochemical Aufraushi. Again, this aluminum alloy is significantly improved by the reduction of the aluminum carbide content according to the invention in relation to the production of printing plate supports provided with a virtually gas-tight coating.
- the above object is procedurally achieved in that after the electrolysis of the alumina, the liquid aluminum is fed to a stirring station in which inert gases are introduced with stirring in the liquid aluminum, the duration of stirring and blowing of the inert gas into the molten aluminum in the stirring station for at least 15 min. is and the proportion of aluminum carbides in the aluminum alloy to less than 1 ppm, is lowered.
- the purification steps of aluminum alloys have been aimed at reducing other impurities such as alkaline earth or alkali metals, of course, aluminum carbides were removed from the molten aluminum. For this reason, the aluminum carbide contents of the conventionally produced aluminum alloys were clearly above the values according to the invention.
- the liquid aluminum is fed to a stirring station in which inert gases are introduced with stirring into the liquid aluminum, wherein the duration of stirring and blowing the inert gas into the molten aluminum in the stirring at least 15 min. is.
- inert gases are introduced with stirring into the liquid aluminum, wherein the duration of stirring and blowing the inert gas into the molten aluminum in the stirring at least 15 min. is.
- a reduction of the aluminum carbide content of the molten aluminum results from the fact that the liquid aluminum supplied to the stirring station has been obtained at least partially from cold metal.
- Cold metal is already produced from an electrolysis of alumina aluminum, which has undergone some process steps after the electrolysis, for example, a stirring station.
- the aluminum carbide content of the supplied cold metal is therefore typically much lower than that of a liquid aluminum originating from the electrolysis. It is believed that the burnup of the graphite electrodes used in the electrolysis contribute to the aluminum carbide content of the aluminum melt produced from alumina.
- the aluminum carbide content of the aluminum alloy according to the invention is additionally reduced further by adding aluminum fluorides to the stirring station during the stirring of the liquid aluminum. These remove the alkali metals sodium, calcium and lithium, but also via oxidation, in particular elements such as titanium and phosphorus. At the same time, however, it was found that the aluminum carbide content of the aluminum melt is also reduced.
- the aluminum is further refined according to one Embodiment of the method according to the invention, supplied to the furnace for adding the alloy constituents, wherein the aluminum in the furnace for at least more than 30 min., Preferably at least more than 60 min. after alloying has taken place in the oven by stirring and adding the alloying ingredients.
- This ensures that the aluminum carbide compounds contained mostly in gas bubbles of the previously introduced into the molten aluminum gas together with these can migrate to the surface of the molten aluminum and form part of the dross to be removed from the melt there.
- the aluminum alloy may be subjected to at least one segregation step in which the aluminum alloy is heated to slightly above the solidus temperature of the aluminum alloy so that molten heavily contaminated phases can be extruded from the aluminum alloy.
- These highly contaminated phases of the aluminum alloy additionally contain aluminum carbide compounds, which can be removed in this way from the aluminum melt.
- the inventive method for producing an aluminum alloy for lithographic printing plate supports with respect to reducing the aluminum carbide content can be further improved by filtering the aluminum alloy prior to strand or ribbon casting, the filter having a high filter efficiency for smaller or smaller sized particles equal to 5 ⁇ m. It goes without saying that the filter efficiency of these filters is also high, even for larger particles with a size of significantly more than 5 ⁇ m . It has been found that the aluminum carbides are typically present predominantly in impurity particles larger than 10 ⁇ m , so that filtering the aluminum alloy provides additional reduction of the aluminum carbide content. Since the filtering of the aluminum alloy takes place immediately before the casting of the aluminum alloy, this step, especially in combination with the previously described measures, a high control value attached.
- two-stage filter used consisting of a first ceramic foam filter with a downstream Tiefbettfilter.
- the addition of grain refining material can take place between the two filters in order to ensure the highest possible effectiveness of the ceramic foam filter through the construction of a filter cake and a long service life of the downstream deep bed filter.
- the above-described object is achieved for an aluminum strip for lithographic printing plate support that this is prepared by continuous or discontinuous casting of an aluminum alloy according to the invention with subsequent hot and / or cold forming, wherein the aluminum alloy according to the invention using the inventive Process has been prepared.
- the aluminum strip according to the invention then consists of an extremely low-aluminum-carbide material, so that it is ideally suited for the production of printing plate supports with a gas-tight coating.
- An aluminum strip with only a few aluminum carbide compounds on its surface and in the core material can be provided by removing the rolling oil residues on the aluminum strip for lithographic printing plate supports by annealing and degreasing the strip.
- the aluminum ribbon is made using an acidic or basic medium of a first Degreasing, and then further cleaning using a pickling process so that the removal of aluminum carbide on the surface is even more thorough.
- an aluminum strip with a further reduced amount of aluminum carbide compounds can be provided on its surface.
- the aluminum alloy of the aluminum strip according to the invention itself has very low proportions of aluminum carbide compounds, so that in combination with the almost aluminum carbide-free surface of the aluminum strip, an aluminum strip, ideal for coating with gas-tight coatings, is available for lithographic printing plate supports.
- the above-described object with respect to the use of the aluminum strip is achieved by using the aluminum strip according to the invention for the production of lithographic printing plate supports with a gas-tight coating.
- the production of an aluminum alloy according to the invention begins by an electrolysis 1 of aluminum oxide.
- the liquid aluminum is then fed to a stirring station 2, alternatively or cumulatively to the aluminum obtained directly from aluminum oxide, as shown in the figure, cold metal 3 can be supplied to the stirring station.
- the cold metal contains less aluminum carbide than an aluminum melt produced directly from aluminum oxide, since the latter additionally contains carbon compounds and thus aluminum carbide by burning off the graphite electrodes.
- the minimum gassing and stirring time should be between 10 and 20 min. lie.
- the aluminum melt is fed to a furnace 4.
- a gas flushing with reactive and / or inert gases are carried out in the furnace 4 and the alloying constituents added.
- the gas flushing leads to a further reduction of the aluminum carbide content in the aluminum melt.
- the aluminum alloy is in the oven for a certain period of time, so that the gas bubbles previously dissolved in the melt have enough time to get to the surface of the molten aluminum.
- the standing of the melt in the oven can for a period of 15 to 90 min., Preferably from 30 to 60 min. be made.
- the gas bubbles which have reached the surface of the molten aluminum during gas purging with reactive and / or inert gases are skimmed off from the melt by scraping off the aluminum alloy and thus removed from the aluminum alloy.
- the dross then contains the aluminum carbides flushed out of the aluminum melt.
- the liquid aluminum alloy is fed to a rotor degassing 5, which operates, for example, by the SNIF process (Spinning Nozzle Inert Flotation), for example purged with argon and / or chlorine.
- the fine gas bubbles sweep the contaminants to the bath surface, with chlorine being particularly liable to cause the sodium and calcium contaminants to harden to salts, which are then deposited with the gas bubbles in a scratch layer on the aluminum alloy. The scratching layer is then removed again.
- the aluminum alloy according to the invention is preferably filtered before casting Filter 6 subjected, which has a high filter efficiency for particles with a size of less than or equal to 5 ⁇ m.
- filters 6 having a filter efficiency of at least 50% can be used for these particles. Since aluminum carbides generally to larger particles, mostly adhered with a size of about 10 ⁇ m, can be further reduced aluminum carbide content of the aluminum alloy effectively by the filtering step. Subsequently, the aluminum alloy can be fed to a continuous or discontinuous casting process 7, 8.
- the aluminum alloy may be subjected to at least one segregation step in a segregation station, not shown, in which the aluminum alloy is heated to a temperature just above the solidus temperature of the aluminum alloy. Heavily contaminated phases of the aluminum melt melt below the solidus temperature so that they can be pressed out of the molten aluminum and removed. Since the contaminated phases usually also contain aluminum carbides, their proportion in the aluminum alloy according to the invention is further reduced by the optional segregation.
