Definitions
- the invention relates to aluminum alloy strips having a high homogeneity of surface, intended for applications requiring good visual quality or particular optical properties, such as for example reflectors or anodized sheets for building and decoration. It also relates to a process for manufacturing these bands by continuous casting between cylinders.
- Another surface defect that is usually observed consists of mechanical scratches parallel to the long direction of the strip; it is a roughness defect.
- the underside has the quality of a usual "mill finish”.
- British patent application GB 2198976 describes an asymmetrical injector device making it possible to increase the speed of casting and therefore the industrial efficiency of a continuous casting machine between rolls; the document does not report an improvement in the surface of the products obtained, which was not the subject of the invention which it describes.
- US Patent US 5,350,010 seeks to optimize the surface quality of the strips intended for the manufacture of offset printing plates by fine control of the grain size of the final product, which supposes compliance with a certain composition of the metal. and the control of certain process parameters, which occur downstream of the continuous casting, such as the reduction rate per cold rolling pass. Knowing that the surface defects present on the raw casting strip will not usually disappear during the following cold rolling operations, this approach, in the opinion of the applicant, does not seem to attack the source of the defects but seeks to minimize only their consequences on the finished product.
- patent application EP 0821074 also discloses a process for transforming a strip obtained by continuous casting between rolls, allowing the manufacture of offset plates. The Applicant notes that none of these approaches makes it possible to obtain surfaces which meet the requirements of high optical and visual homogeneity 4 directly by continuous casting between rolls, optionally followed by one or more cold rolling passes.
- the object of the present invention is to obtain, by continuous casting between cylinders, strips of aluminum alloys having, on at least one face, a high homogeneity of surface and usable for applications which were not open to them until now. It should be noted that the vast majority of these applications only imperatively require a very homogeneous surface finish for one of the two faces. It is therefore not annoying that the present invention improves the surface condition dramatically for only one of the two faces.
- the strips according to the invention also have a surface homogeneity such as the value of the asymmetry of the distribution of the 2D roughness amplitude (Sk or skewness parameter), measured by a technique based on an optical scanner described below. , lies between -0.2 and +0.3, and preferably between -0.1 and +0.2
- the 3D roughness (parameter E k ), determined by a mechanical probe parallel to the rolling direction according to a method described here below, is less than 15, and preferably less than 8
- the invention also relates to a process for manufacturing strips of aluminum alloy by continuous casting between two cooled cylinders, from a casting tray containing the liquid metal connected to an injector, comprising an upper lip and a lip. lower, bringing the liquid metal into the gap between the two cylinders, in which the upper lip of the injector is set back by at least 2 mm, and preferably by at least 5 mm, relative to the lower lip
- the height of liquid metal in the pouring pan measured from the median casting plane, is kept less than 30 mm, preferably less than 25 mm.
- FIG. 1 represents a cross section through a plane perpendicular to the axis of the cylinders of a continuous casting machine between cylinders, according to the invention.
- FIG. 2 represents an example of recording the optical roughness index S N le along a measurement profile for a strip according to the invention of Example 1
- FIG. 3 represents an example of recording the optical roughness index S along a measurement profile for a tape of the prior art of example 1 Description of the invention
- the surface homogeneity of the upper face of the strips is assessed from two different aspects: the presence of roughness defects (mechanical scratches parallel to the long direction), and the presence of gray level oscillations (streaks perpendicular to the long direction) .
- the optical roughness value S N was measured using an optical surface measurement system RM 400 from RODENSTOCK This device defines and measures S N between 4 and 100, for roughness superficial between 5 and 2000 nm. It is based on the principle of the diffusion of radiation by a rough surface.
- the surface to be evaluated receives a beam of infrared rays, part of which is re-emitted, the angular distribution of the scattered rays depending on the morphology of the surface.
- the index S N is measured continuously on profiles of length 5 cm by scanning a beam with a diameter of 0.5 mm, and we measure on each sample 3 profiles in the long direction and 3 profiles in the cross direction taken in the same area with a diameter of about 10 mm. For each profile, the aberrant isolated peaks due to accidental mechanical scratches visible to the naked eye are eliminated, distinguishing them from the wavelets to be characterized.
- the maximum value, the minimum value and the average value of S N , the difference ⁇ SN between the maximum value and the minimum value, as well as the variation of, are determined from the recorded curve, as indicated in FIGS. 2 and 3. This index, defined by the ratio: ⁇ S N / S N mean.
- the parameter L * a * b * was calculated according to standard ASTM D2244-89, ⁇ 6 2
- the samples were characterized by the average value of the parameters L *, and by the standard deviation on this parameter
- twenty measurements following a generator perpendicular to the oscillations were carried out This allows, with a unilateral risk of 0.05, to differentiate two series of measurements whose standard deviation ratio is 2.17
- This test makes it possible to reproduce the visual classification of samples, except for samples showing a pitch of oscillation much less than the diameter of the measurement area
- a third way to characterize the gray level oscillations is the use of a scanner to obtain the gray level mapping, followed by the two-dimensional roughness analysis by numerical methods known to those skilled in the art.
- the area to be studied has been selected interactively, the reference grid and the edges of the remaining image are eliminated, typically 1 to 3 cm on each edge, and if necessary, peripheral zones showing veils or spots not representative of the gray level oscillations to be characterized
- the useful zone thus obtained must have a minimum size of 12 cm x 12 cm
- the four roughness parameters are then calculated.
- the mean absolute deviation Ra, the mean quadratic deviation Rq, the maximum roughness Rt, and the asymmetry of the amplitude distribution (skewness) Sk defined as
- the Sk value is between - 0.2 and + 0.3
- a Sk value between - 0, 1 and + 0.2 is preferred
- the applicant has found values 9 between - 0.45 and - 1.38 for samples of alloy 8011 obtained by the continuous casting process between cylinders according to the prior art.
- a three-dimensional mechanical roughness method was used.
- the sample is placed on a TIXY 200 cross table.
- the probe (model FRW 750 from Mahr Measurements), with a radius of curvature of 5 ⁇ m, was conditioned by a Perthometer PRK device from Mahr Measurements.
- the data was recorded using an analog-digital conversion card in a microcomputer.
- the dimension of the measurement field was 20 mm x 20 mm, with a pitch of 40 ⁇ m in x and y.
- the theoretical depth resolution was given by the maximum amplitude of the probe (100 ⁇ m) and the characteristics of the microprocessor (16 bit), that is to say approximately 0.024 ⁇ m.
- the roughness in three dimensions was calculated with software provided by the company Saphir according to the following equations:
- N M - ⁇ F.
- N is the number of points in x
- M the number of points in y
- Zo the average altitude on the observation surface according to i N M
- the Ek parameter sometimes called kurtosis in the English language, characterizes the flattening of the distribution; it takes the value of 3 for an ideal Gaussian.
- the average variation of S N is greater than 50%, both for the raw casting tapes and for the cold rolled tapes
- the average variation is less than 20% in all cases
- the difference ⁇ S N is less than 20 for the raw casting tapes, and less than 12 for the cold rolled tapes up to a thickness between 4 and 0.1 mm, and having undergone pickling before anodizing basic.
- the machine comprises a tundish (1) supplied with liquid aluminum alloy and connected to an injector (2), consisting of a lower lip (3) and an upper lip (4), bringing the liquid metal in the meantime between the two cylinders (5) and (6) rotating in opposite directions.
- the strip (7) comes out solidified on the other side of the gap between cylinders.
- the modification according to the invention consists in using an injector having an upper lip (4) set back a distance (d) from the lower lip (3)
- This withdrawal (d) is at least 2 mm and, preferably at least 5 mm
- the removal of the upper lip of the injector also allows a finer positioning of the injector, which avoids accidental friction on the surface of the cylinders, and thus indirectly improves the surface condition of the underside of the strip. casting.
- a metal height of less than 25 mm and a shrinkage of the upper lip of the injector of at least 25 mm the applicant has succeeded in manufacturing shiny products from alloys of the 1000 and 8000 series finished by rolling with polished cylinders (rolling known as "skin pass") which had properties of use identical to known products, developed by the more expensive way of semi-continuous casting and hot rolling. These products could be used for the manufacture of flat, folded or stamped light reflectors.
- the invention is applicable to all aluminum alloys capable of being continuously cast between cylinders. By way of example, the applicant has obtained good results with certain alloys of the 3000 series and with certain alloys of Al-Mg type with a low magnesium content such as 5005.
- the invention is particularly advantageous for AlFeSi alloys of the 1000 and 8000 series, containing from 0.01 to 2% by weight of iron, and from 0.1 to 2% of silicon. Indeed, these alloys, when they are continuously cast between cylinders, have significantly higher mechanical characteristics than those obtained by traditional casting and hot rolling, which facilitates their "shiny" rolling.
- One of the reasons for the higher mechanical strength of the bands obtained by continuous casting for this type of alloy is that the quantity of iron in solid solution in aluminum is higher. For an alloy containing more than 0.01% (100 ppm) of iron, the quantity of iron in solid solution is greater than 50 ppm + 0.03 x (Fe content in ppm).
- Another advantage of having a high level of iron in solid solution is, for a given iron content, to reduce the intermetallic compounds with iron, the presence of which on the surface is a source of optical defects.
- the invention is also particularly advantageous for low Mg alloys (Mg ⁇ 1.5%). 12
- a grain size is obtained at the surface, defined as the average width of the grains at the surface, measured perpendicular to the direction of rolling by image analysis, less than 20 ⁇ m, and often 15 ⁇ m, both on the strips. raw casting only on cold rolled strips, which reduces certain appearance defects such as lineage. This characteristic of the strips according to the invention is also favorable for subsequent shaping, for example by stamping.

- the diameter of the cylinders was 1150 mm, with an air gap between the two cylinders of 2.3 mm.
- the Styrite ® brand ceramic injector had an upper lip set back 7 mm from the lower lip, and was fed by a tapping pan with a height of liquid metal of about 18 mm.
- the casting was made at a width of 1370 mm, a casting strip thickness of 3.6 mm, a casting speed of 1.6 m / min and a force between rolls of 800 rpm of strip width.
- the strip was then cold rolled to a thickness of 0.4 mm. strips of the same composition were also prepared by the usual method of vertical semi-continuous casting, hot rolling of the plates then cold rolling to the same thickness of 0.4 mm at two different work hardening rates.
- Strips of the same composition were also prepared, always with continuous casting between JUMBO 3 CM ® cylinders from Pechiney Rhenalu but with an injector from the front without removing the upper lip. These strips followed the same process up to a thickness of 0.4 mm as the strips according to the invention.
- the strips according to the invention and the strips resulting from a continuous casting between cylinders with an injector of the prior part were then subjected to two finishing passes with glossy cylinders from 0.4 mm to 0.35 mm.
- electrolytic brightening then anodization with sulfuric acid with a thickness of 1 ⁇ m, the optical properties of the strips were measured by the RM 400 system from the company RODENSTOCK. The results are given in Table 2.
- Strips according to the invention 7.4 6.4 1 14%
- the injector also made of Styrite ® ceramic, had an upper lip set back 10 mm from the lower lip and was supplied by a tapping pan with a height of liquid metal of around 18 mm.
- the strip width was 1370 mm, the thickness of the casting strip 3 mm, the casting speed 2 m / min and the effort between rolls of 900 t per meter of strip width.
- the strips thus cast were then cold rolled to a thickness of 0.8 mm and then underwent two rolling passes with shiny rolls up to 0.5 mm. Strip samples were taken progressively, first from raw casting strips at 3 mm, then from strips after cold rolling of 0.8 mm, and finally from strips after "glossy” rolling at 0, 5 mm.
- the samples of raw casting strips at 3 mm were treated by sulfuric anodization with a thickness of 1 ⁇ m.
- the strip samples after cold rolling to 0.8 mm underwent basic pickling over 10 ⁇ m and then sulfuric anodization with a thickness of 1 ⁇ m.
- the strip samples after brilliant rolling to 0.5 mm underwent successively an electrolytic brightening and a sulfuric anodization of thickness 1 ⁇ m.
- Strips of the same composition were also prepared, always with the continuous casting between JUMBO 3 CM ® cylinders from Pechiney Pvhénalu but with an injector from the front without removing the upper lip.
- Thickness SN S max S n min n max S n S n max-min mm - S n min / n S means
- grain sizes on the surface of 12 ⁇ m were measured while the strips of the same composition, having undergone the same ranges of cold rolling but resulting from the conventional process (vertical semi-continuous casting then hot rolling of the plates) have grain sizes on the surface of the order of 70 ⁇ m.
