Definitions
- the invention relates to the steel industry. More specifically, it relates to the manufacture of steel strips intended to be transformed into thin packaging, such as cans for drinks and canned food.
- the conventional process for manufacturing steel strips intended to then be transformed into thin packaging, in particular for beverages and food products comprises the following stages:
- this cold rolling can be carried out in a single step, or in two steps which can be separated by a heat treatment, according to the final thickness desired for the strip;
- the thicknesses of the final strips after cold rolling and annealing are of the order of 0.09 to 0.40 mm. These strips are then cut into sheets and / or blanks, which are stamped to form the desired packaging.
- This manufacturing chain is long and costly in energy, because it requires the use of separate installations.
- rolling the slabs on the belt train is expensive, in particular because these slabs must first be reheated to high temperature.
- the band train is a tool requiring a high investment.
- the strip thus cast then undergoes pickling, a first cold rolling, a recrystallization annealing and a second cold rolling.
- the total reduction rate undergone by the strip during cold rolling is between 85 and 95% if it is desired to obtain satisfactory results on the rate of the drawing horns, the anisotropy coefficient r and the planar anisotropy ⁇ r.
- the casting between rolls can be followed by a light hot rolling with a reduction rate of 20 to 50%, or even more.
- the manufacture of the hot strip which must then undergo rolling cold and associated treatments is faster and more economical. However, the need for subsequent cold rolling in two stages separated by annealing tempers these advantages.
- the object of the invention is to propose a more economical method than the known methods for obtaining cold-rolled steel strips usable for the manufacture of packaging, in particular for food packaging such as drink cans.
- the subject of the invention is a process for manufacturing strips of carbon steel, in particular steel for packaging, according to which: - it is cast in the form of a thin strip of 0.7 to 10 mm thickness, directly from liquid metal, a steel having a composition suitable for use as steel for packaging;
- the subject of the invention is also a strip of carbon steel, in particular steel for packaging, characterized in that it is capable of being obtained by the preceding process.
- the invention is based on the use of a casting process between rolls followed by at least one step of hot rolling in line and of a particular cooling of the strip.
- a hot strip is thus obtained which tolerates then only undergoing a single cold rolling step (apart from the conventional final pass through the skin-pass) in order to be given the properties which make it suitable for the manufacture of steels for packaging.
- the process according to the invention begins with the casting in the form of thin strips 0.7 to 10 mm thick (preferably 1 to 4 mm) of a semi-finished product with low or ultra-low carbon content. a steel which can be used for packaging of conventional composition.
- This composition for the main elements present, meets the main criteria (the percentages are expressed as weight percentages): 0% ⁇ C ⁇ 0.15%; 0% ⁇ Mn ⁇ 0.6%; 0% ⁇ P ⁇ 0.025%; 0% ⁇ S ⁇ 0.05%; 0% ⁇ Al ⁇ 0.12%; 0% ⁇ N ⁇ 0.04% o.
- This steel also contains the usual impurities resulting from the production, and possibly alloying elements in small quantities which will not adversely affect the properties of the products during their shaping or their use as steels for packaging (it is thus known in some steels for packaging, introduce a few thousandths of% boron), the rest being iron.
- the alloying elements generally absent, may possibly be present in contents of up to 1%; These elements are notably Si, Cr, Ni, Mo, Cu. For regulatory reasons, certain alloying elements must be excluded when the steel is intended for packaging; these elements are for example lead, cadmium and arsenic.
- the continuous casting of thin strips directly from liquid metal is a technique which has been tried for several years for the casting of carbon steels, stainless steels and other ferrous alloys.
- the most commonly used technique for casting thin strips of ferrous alloys, and which is in the process of reaching the industrial stage, is the technique known as “casting between cylinders”, according to which liquid metal is introduced between two cylinders brought close together. horizontal axes, rotated in opposite directions and internally cooled. The casting space is closed laterally by refractory plates applied against the flat side faces of the cylinders.
- Solidified metal "skins" form on each of the cylinders, and meet at the neck (the area where the gap between the cylindrical lateral surfaces of the cylinders is smallest and corresponds substantially to the thickness desired for the strip ) to form a solidified strip.
- This technique is particularly recommended for the invention because it gives access to strip thicknesses of a few mm, and reference will be made to this in the following description.
- other methods of direct casting of thin strips can be used, such as casting between two moving strips which makes it possible to cast products a little thicker than casting between rolls.
- one of the advantages of casting between cylinders is the possibility of obtaining, if necessary, extremely thick transverse strip thickness profiles, thanks to the excellent mastery of the curvature of the cylinders which the modes allow. of putting this most advanced process into practice (see, for example, document EP 0 736 350).
- the strip preferably crosses an area such as an enclosure inerted by gas blowing, where it is subjected to a non-oxidizing environment (a neutral atmosphere of nitrogen or argon, or even a atmosphere containing a certain proportion of hydrogen to make it reducing), in order to avoid or limit the formation of scale on its surface.
- a non-oxidizing environment a neutral atmosphere of nitrogen or argon, or even a atmosphere containing a certain proportion of hydrogen to make it reducing
- - a thickness of less than 3 mm (typically 0.9 mm) which, in conjunction with the reduction rates which will be applied during the cold rolling which will follow, will make it possible to obtain final strips having the desired thickness;
- - a metallurgical structure which, still in conjunction with the treatments subsequently undergone by the strip, makes it possible to obtain on the strip the mechanical properties required for the future use of the metal, for example as steel for packaging;
- a single step of hot rolling of the strip is carried out, ending at a temperature higher than the temperature Ar 3 of the cast steel, in other words in the austenitic field.
- This hot rolling is carried out with a minimum reduction rate of 20%, and preferably this rate is greater than 50%.
- the functions of this hot rolling are:
- This single hot rolling step can be carried out by passing the strip through a single rolling stand. It can also be carried out more gradually by passing the strip through two or more rolling stands.
- the first cage can, for example, apply to the strip a reduction rate which is only sufficient to close the porosities, and the second cage then provides the major part of the reduction in thickness enabling the two other functions of hot rolling to be fulfilled.
- the main thing is that the overall reduction rate caused by this or these passages in the successive cage or cages and the temperature of the strip after its passage in the last cage are within the prescribed ranges of values.
- hot rolling takes place in two stages, separated by reheating, and possibly by descaling.
- the first of these steps is carried out either in the austenitic domain, or in the ferri tic domain of the casting strip, with a reduction rate of 20 to 70%. It has functions identical to those of the single hot rolling step of the first variant, and can also be carried out by passing the strip through one or more successive rolling mill stands.
- this first rolling step takes place in the ferritic field when it is desired to obtain a final thickness of the strip that is small, because less effort is required to deform the strip evenly over its entire width than when the strip is in the austenitic domain.
- this first hot rolling step is carried out by distributing it over several cages, it is however possible to begin this first step in the austenitic field, for example by a relatively light rolling which would mainly aim at closing the porosities, and finish in the ferritic area where the rest of the thickness reduction would be carried out.
- the strip is allowed to cool down to the ferritic region if it is not already there (if necessary using a slight forced cooling), then a treatment is applied to it. thermal reheating which brings it back into the austenitic domain, therefore above the temperature Ar 3 . This causes an additional phase change in the strip, which results in an even further refinement of the grains of the metallurgical structure.
- the second stage of hot rolling is carried out, in the austenitic field, with a reduction rate of 10 to 30%.
- This second hot rolling has the essential function of correcting the geometric defects (bad planarity, saber ...) that the first hot rolling could have caused.
- Intermediate heating can be achieved by means of an inductor through which the strip passes. For a strip 0.75 mm thick and 850 mm wide running at a speed of 200 m / min, a power of 1.04 MW is necessary if a temperature rise of 100 ° C is sought.
- the two variants which have just been described therefore have the common point of ending with a rolling carried out on the strip in the austenitic phase, which therefore ends above the temperature Ar 3 .
- the method according to the invention continues with cooling of the strip which includes a forced cooling step at a speed of 80 to 400 ° C / s, preferably 100 to 300 ° C / s.
- This cooling ends in the ferritic domain of cast steel, and in general brings the strip to a temperature close to its winding temperature. Its purpose is to avoid excessive growth in the size of the grains before winding and during the stay of the strip in the form of a reel.
- This winding temperature is typically less than 750 ° C.
- the winding temperature can be chosen around 550 ° C or 600 ° C or 700 ° C in order to favor more or less the precipitation of aluminum nitrides.
- This forced cooling can start immediately after the austenitic rolling of the strip, but it is advisable to start it only after having allowed the strip to cool at low speed (about 10 ° C / s, which is accessible by a simple exposure in the open air) and pass into the ferritic domain, therefore below Ar 3 .
- the accelerated cooling should preferably not start at a temperature below Ar 3 - 10 ° C.
- the use of rapid cooling before winding avoids the presence of large grains in the skin of the strip, which are particularly undesirable on steels for packaging. Indeed, these must have, after cold rolling, a very high homogeneity of their final characteristics.
- the strip wound and then unwound then undergoes cold rolling at a reduction rate of at least 85%, preferably more than 90%>.
- This cold rolling can perfectly be carried out by simple reduction, that is to say in a single stage, and not imperatively in two stages with intermediate annealing as was the case in the document JP 09-001207 already cited (cold rolling double reduction). Stamping capacities comparable to those obtained by known methods are obtained, and strip thicknesses less than 0.09 mm of known methods are available without having to resort to double reduction cold rolling. . If it is not desired to obtain thinner strips than usual, the conventional thicknesses can be obtained with lower reduction rates during cold rolling, which is more economical. It is, of course, possible to carry out a cold rolling of the strip in double reduction if one wishes to obtain an even smaller thickness or higher mechanical characteristics
- Table 1 which gives examples of final thicknesses of the strip as a function of its initial thickness after casting and of the rolling rates applied during the hot rolling steps (in one or two steps depending on the chosen variant) and cold rolling
- the strip undergoes the usual annealing (base or continuous) intended to give it its mechanical properties.
- This annealing can be followed, as usual, by pickling, coating and / or passing to the skm-pass.
- the exit speeds of the strip from the hot rolling mill being of the order of 250 m / min or less, these speeds are compatible with placing on a single line of this rolling mill (therefore of the casting line as a whole) and one or more of the cold rolling, annealing and cold treatment operations for steels for packaging, the metal throughput of which is compatible with that of the hot rolling mill.
- the invention finds a preferred field of application in the manufacture of steel strips intended to be stamped to form packaging for beverages or canned food, it goes without saying that it can be applied to the production of strips of steel intended for other uses for which similar qualities would be required for the bands produced
