Definitions

  • Aluminum tapes must simultaneously meet a variety of requirements to provide sufficient quality for lithographic printing plate supports.
  • An area-wide roughening of the aluminum strip must result in a structureless appearance of the aluminum strip without streaking effects.
  • a photosensitive layer is applied, which depending on the application type is baked after application at a temperature of 220 ° C to 300 ° C for 3-10 minutes. Typical combinations of bake times are for example 240 ° C for 10 minutes, 260 ° C for 6 minutes, 270 ° C for 7 minutes and 280 ° C for 4 minutes.
  • the printing plate support may lose as little as possible after firing to strength, so this is still easy to handle and can be easily clamped in a printing device. In the case of large-format printing plate supports in particular the handling after the burning of the photosensitive layer is problematic. Finally, the printing plate should survive later in use as many printing cycles, so that the aluminum strip should have the highest possible bending fatigue strength.
  • EP 2 192 202 A1 investigates how an aluminum alloy strip can be adjusted to a desired final strength so that, for example, a set of coils present in the aluminum strip can be eliminated again, and at the same time high bending cycle cycles and good roughening properties can be provided. By choosing the Eisenglühdicke depending on the aluminum alloy composition, the goal could be achieved here.
  • the JP H11229101 also discloses the processing of magnesium-free aluminum alloys containing magnesium only as an impurity at levels of at most 0.05% by weight. Magnesium levels are also considered problematic.
  • magnesium offers particular advantages in terms of fatigue resistance when using the printing plate supports and the roughening of the printing plates. Therefore, magnesium is alloyed to a specified content of the aluminum alloy.
  • the ribbons for lithographic printing plate supports are generally not rolled in rolling stands with multiple stitches. Maximum control of the individual cold rolling passes is desired. In a simple cold rolling pass, however, it is sometimes necessary to cool the strips after each cold roll pass in the coil until they can be used again for a next cold-rolled pass. Become too big Stichabsure made in a cold roll pass, area of the surface of the aluminum strip material can be broken, resulting in surface defects and a streaky appearance of the surface. Due to the risk of surface defects, experts in the field of magnesium-containing aluminum alloys have hitherto refrained from the use of large punctures above about 50% reduction per cold rolling pass during cold rolling. As a result, in a typical production of lithographic printing plate carriers with final thicknesses in the range 0.2 mm to 0.4 mm so far at least four cold rolling passes were required.
  • the object of the present invention is to provide a method for producing an aluminum strip for lithographic printing plate supports comprising magnesium-containing aluminum alloys, with which aluminum strips can be produced for lithographic printing plate supports with high quality and at the same time the costs can be reduced.
  • the above-described object is achieved for a process for producing an aluminum strip for lithographic printing plate support that during cold rolling of the hot strip, the product of the relative end thicknesses of the aluminum strip after the first and after the second cold rolling pass of the aluminum strip 17% 22%.
  • the relative final thickness (b) after a cold rolling pass is the thickness of the aluminum strip after a cold rolling pass in relation to the starting thickness before the cold rolling pass in percent, ie the quotient of resulting thickness and initial thickness.
  • the product P of the relative end thicknesses b 1 and b 2 of the first and second cold rolling passes then the relative final thickness in relation to the initial thickness before both cold rolling passes and thus a measure of the thickness decrease of the aluminum strip within the first two cold rolling passes in relation to the starting thickness of the aluminum strip before Cold rolling according to:
  • a 1 and a 2 are respectively the percent reduction of the first and second cold rolling pass in percent.
  • a preferred embodiment of the method according to the invention is provided by the fact that during cold rolling of the hot strip, the product of the relative final thicknesses of the aluminum strip after the first and after the second cold roll pass is preferably 17% to 20%. This achieves a good compromise with regard to process reliability for providing high surface qualities and the possibility of saving a cold roll pass.
  • the production of an aluminum strip with a final thickness of 0.1 mm to 0.5 mm after cold rolling can be achieved according to a further embodiment of the method in two or three cold rolling passes, when the hot strip thickness from 2.3 mm to 3.7 mm, preferably 2 , 5 mm to 3.0 mm. Below 2.3 mm there is a risk that during hot strip production the hot strip may collapse during winding. Above 3.7 mm Hot Strip Thickness, excessively high passes for the first or second cold roll pass must be selected to reduce the number of cold rolling passes. Too high a choice of cold rolling pick-up is not only the risk of surface defects on the aluminum strip, but also the risk of damage to the cold roll itself. A hot strip thickness of 2.5 mm to 3.0 mm prevents both the collapse of the hot strip and the use Too high Stichabtsum during cold rolling.
  • the first cold rolling pass is carried out with a maximum reduction of 65%, preferably with a maximum of 60%. It has been found that above a 65% reduction in the first cold roll pass after hot rolling the risk of surface defects increases significantly. At a maximum of 60% reduction in the first cold roll pass, even more homogeneous surfaces in the aluminum strip are preferably achieved.
  • the second cold roll pass it was found that this preferably has a maximum reduction of 60% in order to reliably avoid corresponding errors in the end product process.
  • the second cold rolling pass is therefore to be assessed more critically with regard to the surface quality.
  • Both the first and the second cold roll pass preferably have more than 50% reduction in stitches, since this can better distribute the stitch decreases to achieve the desired relative final thicknesses on both cold roll passes. Overall, then in both cold rolling passes no maximum Stichab remain necessary.
  • three cold rolling passes are made to final thickness, wherein the final thickness of the aluminum strip after cold rolling is 0.2 mm to 0.4 mm. So far, at least four cold rolling passes have been required for these final thicknesses. In particular, for end thicknesses of 0.2 mm to 0.4 mm, such a method can be provided, which in addition to an adequate surface quality has reduced costs.
  • the inventive method can contribute to cost reduction.
  • the third or fourth cold rolling pass preferably the last cold rolling pass of the cold rolling, preferably has a maximum stitch loss of 52%, so that the third or fourth or last cold roll pass affecting the surface has as little influence as possible on the surface quality of the aluminum strip.
  • the selected range of the alloying constituent silicon ensures in electrochemical roughening that a high number of sufficiently deep depressions can be introduced into the aluminum strip, which ensure optimum absorption of the photosensitive layer .
  • the aluminum alloy preferably has almost no chromium.
  • the chromium content is limited to a maximum of 100 ppm, preferably a maximum of 50 ppm. Higher chromium contents have been found to be negative for the roughening properties of the aluminum strip during electrochemical roughening.
  • Zinc lowers the electrochemical potential of the aluminum alloys of the aluminum strip so that the electrochemical roughening is accelerated.
  • Zinc is therefore present in the aluminum alloy at a level of up to a maximum of 500 ppm.
  • Higher zinc contents in turn negatively influence the roughening properties of the aluminum strip.
  • the presence of zinc with a content of 50 ppm to 250 ppm reliably leads to an accelerated roughening of the aluminum strip without negative effects on the surface.
  • the aluminum strip according to the invention is moreover almost free of titanium. It contains less than 0.030% by weight of titanium, which negatively influences the properties of the aluminum alloys during electrochemical roughening above the stated limit value.
  • unavoidable impurities to a maximum of 0.03 wt .-% and a maximum of 0.15 wt .-% may be present without affecting the properties of the aluminum alloy strip in the given manufacturing process negative.
  • the aluminum alloy according to a next embodiment has a magnesium content of 0.26% to 0.35% by weight, a very good compromise can be achieved from improved fatigue strength properties of the printing plate supports, good roughening behavior and reduced production costs.
  • Fig. 1 schematically the various process steps in the production of an aluminum strip for lithographic printing plate support.
  • step 1 the aluminum alloy is poured into a rolling ingot.
  • the ingot is subjected to homogenization in step 2, wherein the ingot is heated to temperatures of 450 ° C to 600 ° C with a residence time of at least 1 hour.
  • the homogenised ingot is prepared for hot rolling and then hot rolled at temperatures in excess of 280 ° C.
  • the temperature of the billet is about 450 ° C to 550 ° C.
  • the hot rolling end temperature is usually 280 ° C to 350 ° C.
  • the hot strip thicknesses can be between 2 mm and 9 mm, but preference is given to hot strip thicknesses of 2.3 mm to 3.7 mm.
  • the hot strip is fed to cold rolling in step 4. During cold rolling, the hot strip is cold rolled to final thickness. Cold rolling, and in particular the last cold rolling pass, determines the surface properties of the cold rolled aluminum strip, as the surface topography of the cold roll is transferred directly to the cold rolled aluminum strip. During the rolling pass, errors can occur during cold rolling which are then transferred to the surface or remain directly visible on the surface.
  • the cold rolling according to step 4 can take place both with and without intermediate annealing.
  • the intermediate annealing is carried out at temperatures of 230 ° C to 490 ° C for at least 1 h in the chamber furnace or continuously in the continuous strip furnace for at least 10 s, usually before the last cold rolling pass.
  • the intermediate annealing can be used to set the final strength of the aluminum strip for lithographic printing plate supports in certain areas before the last cold-rolled pass.
  • the intermediate annealing also causes costs, so that a particularly cost-efficient production is preferably carried out without intermediate annealing.
  • Fig. 2 shows a corresponding rolling stand 5, which comprises a take-off reel 6, a take-up reel 7 and a roller assembly 11 with two work rolls 9 and 10.
  • Fig. 2 shows an example of a four-high rolling stand.
  • the roller arrangements can be designed both as a duo, quarto or sexto rolling stand.
  • an additional roller assembly 11 ' so that the belt 8 after passing through the roller assembly 11 in the roller assembly 11' is subjected to a further rolling pass, so a total of a multiple stitch.
  • the aluminum strip 8 can be fed again to a cold rolling pass.

  • Fig. 3a shows at identical magnification
  • Fig. 3b a band regarded as inconspicuous from the surface.
  • the roll bars can be recognized by the ground rolls, which have been pressed in the aluminum strip. Perpendicular to Rolling direction, however, hardly any structures exist, so that the overall impression of the surface is classified as non-streaky.
  • FIGS. 3b) and 3c show, on the other hand, a surface area of an aluminum strip classified as non-homogeneous which results in a streaky appearance of the aluminum strip. A corresponding tape would not meet the surface requirements of lithographic printing plate supports.
  • FIGS. 3b) and 3c ) show surface defects, especially magnified in Figure 3c ), which has transversely extending to the rolling direction areas in which material has been lifted from the surface of the belt. It is believed that this error is due to cold rolling.
  • the width of the problematic area is about 20 ⁇ m perpendicular to the rolling direction and is visible on visual inspection.
  • Aluminum ribbons of six different aluminum alloys A to H have now been applied using the methods discussed above and in US Pat Fig. 1 produced process steps 1 to 3.

  • the product P of the relative final thicknesses after the first and after the second cold-rolled passes is 18.57% to 21.74% due to the reduction in the first two cold-rolling passes.
