Definitions
- the invention relates to a method for producing an aluminum strip for lithographic printing plate supports made of an aluminum alloy, wherein the
- Aluminum alloy of the aluminum strip for lithographic printing plate supports has the following alloy constituents in% by weight:
- 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 pressure plate carrier may lose as little as possible after firing strength, so this is still easy to handle and easy in one
- Printing device can be clamped.
- large-format printing plate supports in particular the handling after the burning of the photosensitive layer is problematic.
- the printing plate should survive later in use as many printing cycles, so that the aluminum strip as high as possible
- European Patent Application EP 2 192 202 A1 has examined how an aluminum alloy strip can be adjusted to a desired final strength so that, for example, a coil set present in the aluminum strip can be removed again and at the same time high bending cycle cycles and good Aufraueigenschaften can be provided.
- Aluminum alloy composition could be achieved here the goal.
- Hthographic pressure plate carriers are known in which a magnesium-free
- Aluminum alloy is processed by applying cold rolling passes with Stichabures above 50%. Magnesium levels above 0.02 wt% are considered problematic in terms of recovery of the cold rolled strip and the appearance of excessively high strengths after cold rolling.
- JP H11229101 also discloses the processing of magnesium-free
- magnesium-containing are magnesium-containing. It has been found that 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 Stichab portions made in a cold roll pass, can be broken out of the aluminum strip partially material of the surface, resulting in
- the present invention the object of a method for producing an aluminum strip for lithographic
- Pressure plate carrier having to provide magnesium-containing aluminum alloys, with which aluminum strips for lithographic
- Print plate carrier produced with high quality and at the same time the costs can be reduced.
- the above-mentioned object is achieved for a method 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 15% 24%, preferably 17% to 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.
- Kaltwalzstiches then gives the relative final thickness in relation to the initial thickness before both cold rolling passes and thus a measure of the thickness decrease of
- Thickness reduction of the aluminum strip in the first two cold rolling passes opened the possibility to save a complete cold rolling pass in the manufacturing process. Surprisingly, it was found that the
- the hot-rolled aluminum strip preferably passes through the following steps in compliance with the specification for the product of the first two cold-rolling passes:
- 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 end thicknesses of the aluminum strip after the first and after the second
- Cold rolling 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 the hot strip during hot strip production may be damaged
- Cold rolling-off acceptance not only involves the risk of surface defects on the aluminum strip, but also the risk of damaging the cold roll itself.
- a hot-rolled strip thickness of 2.5 mm to 3.0 mm prevents both the collapse of the hot strip and the use of high pass rates during cold rolling.
- the first cold rolling pass is carried out with a maximum reduction of 65%, preferably with a maximum of 60%. It turned out that above one
- Stitch loss of 65% in the first cold-rolled pass after hot-rolling significantly increases the risk of surface defects. Preference is given to a maximum of 60%
- this preferably has a maximum reduction of 60% in order to avoid corresponding errors in the
- 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 the number of stitches, since this reduces the number of passes required to reach the
- desired relative end thicknesses can be better distributed to both cold rolling passes. Overall, then in both cold rolling passes no maximum
- 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.
- Production of aluminum strips in the condition H19 and aluminum strips with intermediate annealing in the state H18 can be produced according to the invention.
- the third or fourth cold roll pass preferably the last cold roll pass of the
- Kaltwalzens preferably has a maximum reduction of 52%, so that the third or fourth or last, the surface more strongly influenced cold rolling pass has the least possible impact on the surface quality of the aluminum strip.
- Aluminum strip consisting of an aluminum alloy with the following
- Cu maximally 400 ppm, preferably maximally 100 ppm
- Zn ⁇ 0.05% preferably 50 ppm to 250 ppm
- Alloy composition is due.
- the selected range of the alloying constituent silicon from 0.05% by weight to 0.25% by weight, ensures that in electrochemical thawing, a high number of sufficiently deep
- the iron content of 0.2% ⁇ Fe ⁇ 1%, preferably 0.3% ⁇ Fe ⁇ 1%, particularly preferably 0.3% ⁇ Fe ⁇ 0.6% or 0.4% ⁇ Fe ⁇ 0.6% provides in combination, in particular with the manganese content to a maximum of 0.30 wt .-% for a heat-resistant aluminum alloy, which after baking the photosensitive layer has only a small decrease in strength with respect to yield strength and tensile strength.
- the preferred manganese content of up to 0.30 wt .-%, preferably 30 ppm to 800 ppm, ensures, as already stated, in combination with the iron content improved heat resistance of the aluminum strip after a baking process and affects the flexural fatigue of the
- 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
- 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 at a level of 50 ppm to 250 ppm results
- the aluminum strip according to the invention is moreover almost free of titanium. It contains less than 0.030% by weight of titanium, which above the stated limit value, the properties of
- Impurities to a maximum of 0.03 wt .-% and a maximum of 0.15 wt .-% be present without affecting the properties of the aluminum alloy strip in the given manufacturing process negative.
- FIG. 1 is a schematic view of the basic process steps for producing an aluminum strip it for lithographic printing plate support
- Fig. 2 is a schematic sectional view of the implementation of a
- step 1 shows schematically the various process steps in the production of an aluminum strip for lithographic printing plate supports.
- step 1 the aluminum alloy is poured into a rolling ingot.
- the ingot is subjected to homogenization in step 2, wherein the
- Rolling bar is heated to temperatures of 450 ° C to 600 ° C at 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.
- the cold rolling, and in particular the final cold rolling pass determines the surface properties of the cold rolled aluminum strip, since the surface topography of the cold roll is directly on the cold rolled
- Aluminum band is transmitted. During the rolling pass, errors may occur during cold rolling, which are then transferred to the surface or on the surface
- lithographic printing plate supports inhomogeneous looking, for example, striped surfaces can not be accepted.
- 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 unwinding reel 6, a take-up reel 7 and a roll arrangement 11 with two work rolls 9 and 10.
- 2 shows an example of a quarto
- roller arrangements can be designed both as a duo, quarto or sexto rolling stand. Also indicated is an additional one
- Roller assembly 11 in the roll assembly 11 'another roll pass so a total of a multiple stitch is subjected.
- the aluminum strip can be fed again to a cold rolling pass.
- FIGS. 3 a) to 3 c] are scanning electron micrographs of FIG.
- Fig. 3a shows at identical magnification to Fig. 3b) viewed from the surface as inconspicuous band.
- 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 that one is not classified as homogeneous
- FIGS. 3b) and 3c) show surface defects, in particular enlarged in FIG. 3c), which have regions extending transversely to the rolling direction in which material has been lifted off the surface of the strip. It is believed that this error is due to cold rolling.
- the width of the problematic area is about 20 ⁇ perpendicular to the rolling direction and is visible by visual inspection.
- Aluminum ribbons of six different aluminum alloys A to H have now been used using the above-explained and illustrated in FIG.
- the aluminum alloys differ in particular in different contents in the range of silicon, iron, manganese and magnesium.
- the various alloy compositions are shown in Table 1 with their weight percent alloying ingredients.
- all of the alloys containing chromium less than 50 ppm and unavoidable impurities individually contained a maximum of 0.03 wt% and a maximum of 0.15 wt%.
- the hot strip thickness of the aluminum strips produced was varied from 2.3 mm to 3.0 mm and produced from the different thickness hot strips aluminum strips for lithographic printing plate support by cold rolling without intermediate annealing with a final thickness of 0.274 mm to 0.285 mm.
- the first and second cold rolling passes were selected so that a maximum of three cold rolling passes of final thickness were required starting from the final hot strip thickness, with the last cold roll pass having a maximum stitch loss of 51%.
- 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. That is, by the first two
- the strip was rolled to an intermediate thickness of 18.57% to 21.74% of the hot strip thickness.
- Table 2 shows the embodiments according to the invention and the associated stitching decreases and the values for the product of the relative final thicknesses after the first and second cold rolling passes.
- the K-test is intended to reveal whether, due to the grain distribution, a stiffness effect can be recognized in the surface.
- the samples thus cut are first sanded for 60 seconds with an orbital sander, the orbital sander being wrapped with a damp cloth and scouring milk used to polish the samples.
- a simple household scrub milk can be used here.
- the samples After rinsing the surface with water, the samples are immersed in 30% sodium hydroxide at a temperature of 60 ° C for 15 seconds and then rinsed with water.
- a macroetching takes place in a macroetching solution. This consists of 400 ml of water,
- Neutralization is carried out with a solution of 40.5 ml of 85 percent phosphoric acid and 900 ml of water at room temperature for about 60 seconds. The sample is then rinsed with water and dried at room temperature. After drying, the samples are visually evaluated for streakiness. Reference samples with Numbers from 1 to 10 are used to determine streakiness in the K-test
- the value 10 stands here for non-streaky.
- the value 1 corresponds to a striped appearance. This streakiness is, as already stated, caused by the grain distribution of the aluminum strips and can be evaluated well with this test.
- Nabuclean 60S at 60 ° C for 10 seconds.
- the concentration of the degreasing medium is 15 g / l.
- the sample is immersed in a caustic soda solution and etched at 50 ° C for about 10 seconds.
- the sodium hydroxide solution is 50 g / l.
- the samples are evaluated using also reference samples, each of which is assigned values from 0 to 5, with the value 0 of one as non-streaky and the value 5 of one as is assigned to a striped evaluated surface.
- the pickling test the samples were compared and evaluated with reference samples before and after pickling.
- Stitch tests in the first cold-rolled pass increase the surface quality in the pickling test. In general, it was shown that in spite of a cold rolling pass, a reduction of 60% in the first and in the second cold rolling pass achieved good surfaces in the pickling test.
- Pressure plate carrier can be saved without affecting the surface quality too strong. As a result, a production route can be made available which, while saving a cold rolling pass, is less expensive
- Aluminum bands for lithographic printing plate support can provide. Table 3
