Definitions
- the present invent ion is to obj and a method for lab e r ation of a sheet or a steel strip intended for the sheave ization of a box obtained by emboutissage- ironing, of the beverage can type .
- the present invention also relates to a t O o u l e a steel strip intended for the production of a b Oi t e obtained by drawing -repassage.
- C e t ype boxes typically comprises a bottom, a peripheral skirt and a collar for carrying out the crimping of a lid, which can be easily openable, e t is manufactured in particular by stamping - ironing from a blank cup in a sheet or strip.
- the cup is first subjected to a stamping by relatively severe shrinkage on a press which comprises typically .d'une hand, a fixed die and a support forming a blank holder Externa ⁇ sliding America around said punch and on which the cup rests and, on the other hand, a matrix intended to be applied to the cup according to a force transmitted vertically by an upper slide.
- a press which comprises typically .d'une hand, a fixed die and a support forming a blank holder Externa ⁇ sliding America around said punch and on which the cup rests and, on the other hand, a matrix intended to be applied to the cup according to a force transmitted vertically by an upper slide.
- the cup having a bottom and an edge formed during the stamping operation is then self t calibrated by a slight drawing without using a blank holder, is redrawn with holding frame t are then subjected to an ironing operation which consists in stretching by means of a drawing machine, by successive reductions, the edge to gradually form the peripheral skirt of the box. Then, the bottom is formed on the drawing machine to give it a determined geometry and the neck of the peripheral skirt is formed according to two techniques, either a shrinking technique with matrix, or a tecr.r. qe has to shrink. a -.a wheel.
- the die-shrinking technique involves forcing the neck into a die with a conical entry profile and a cylindrical exit profile.
- a cylindrical piece guides the wall formed at the outlet of the die.
- the force required to allow the deformation of the metal comes from the thrust applied to the bottom of the box and transmitted axially by its peripheral skirt.
- the wheel shrinking technique consists in driving the rotating box which is held between a pusher and a centering ring.
- the free end of the peripheral skirt is engaged on a mandrel and two wheels moving axially form the neck of the box which gradually emerges from the mandrel while still being held between the pusher and the centering ring.
- the profile of the neck is obtained by the simultaneous movements of the knurls, the centering ring and the pusher.
- the box is filled and a cover, for example with easy opening, is crimped on the neck of said box.
- a cover for example with easy opening
- Manganese in the range of 0.15 to 0.25% Nitrogen of the order of:, 00% to 0, C06% Aluminum of the order of G, 03 and 0.05% Phosphorus less than 0.015% Sulfur less than C, Q20% Silicon less than 0.020%, maximum 0 , 08% of one or more of the elements chosen from copper, nickel and chromium, the rest being iron and residual impurities.
- the sheet or strip is produced by a process in which the slab from a continuous casting is hot rolled, then cold rolled to obtain a strip which is subjected to recrystallization annealing at a temperature below Acl.
- This process makes it possible to obtain a strip which has a final thickness of approximately 0.30 mm and to produce from this strip a box whose wall of the peripheral skirt after stamping-ironing has a thickness of the order of 0, 1mm.
- Ma s or. knows that a reduction in the thickness or an increase in the mechanical characteristics of the sheets or cars.des accentuates the phenomena of wrinkling during the preparation of the boxes.
- the pressure exerted by the blank holder can be increased on the sheet blank, but this increase in pressure of the blank holder poses a problem of controlling the flow of the metal during stamping and can therefore cause breaks or tears in the metal, particularly at the connection radii.
- this operation is carried out by sliding a ring on the stretching punch so that this ring can bear on the free edge of the peripheral skirt of the box.
- the stripping ring only presses on a few points of said skirt and very often there is a folding of the skirt during stripping which requires putting the box in the scum.
- Coarse cementite can cause the wall of the peripheral skirt to pierce when the neck is formed and this metal to be torn off during the drawing operation because of the hard particles in the steel.
- the object of the invention is to avoid these drawbacks by proposing a method for producing a sheet or strip intended for producing a box obtained by stamping-ironing which makes it possible to reduce the thickness of the walls of the box and therefore gain weight.
- the subject of the invention is a method for producing a sheet or a strip intended for the production of a box obtained by stamping-ironing, of the beverage can type, from a steel. with the following weight percentage composition: - Carbon less than 0.008%,
- the invention also relates to a steel sheet or strip intended for the production of a box obtained by stamping-ironing, of the box-drink type, characterized in that it is obtained by the process mentioned above.
- the manufacture of a can, of the beverage can type, by stamping-ironing consists in cutting a blank from a sheet of steel or a strip of steel, then stamping this blank by relatively severe shrinking on a press to form a cup.
- the cup comprising a bottom and an edge is calibrated and is subjected to an ironing operation consisting in stretching, by successive reductions, the edge to gradually form the peripheral skirt of the box.
- the ron ⁇ is a.ors form to give it _a determined geometry and the core of the peripheral ⁇ upe is formed either by a shrinking technique with matrix, or by a shrinking technique with the wheel.
- the invention proposes to develop this type of box by this technique of embou ⁇ weaving-ironing from a very low carbon steel having the composition as a percentage by weight: - Carbon less than 0.008%,
- the slab is hot rolled into a strip of thickness between 1.8 and 2.5mm and preferably between 2 and 2.4mm, then the strip is cold rolled with a reduction rate to bring said strip to a thickness between 0.26 and 0.32 mm and submitted to recrystallisation annealing at a temperature higher in NCI ⁇ Acl and finally re-rolled in the cold with a reduction rate between 28 and 35% for causing said strip at a thickness between 0.18 and 0.22mm.
- the rate of horns is equal to -0.2.
- 0.18mm has a rate of horns equal to -0.05, which is a coefficient very close to 0, therefore representative of a steel with a very low propensity to form horns. It is therefore particularly important to respect the cold rolling and re-rolling after annealing rates as well as to apply a high hot rolling rate in order to develop a hot rolled strip with a thickness of less than 3 mm, preferably between 1.8 and 2.5 mm.
- the crames having any of the compositions indicated in table 1 above were subjected to a treatment which consists in hot rolling each slab into a strip, then in cold rolling this strip and in subjecting said strip to recrystallization annealing at a temperature below Acl and finally re-cold rolling.
- the steel sheets or strips obtained by this process were subjected to tests in order to determine the elastic limits Re and Rm in the long direction and in the transverse direction as well as the rate of horns ⁇ C.
- M notes in this table that the steels G and H, although satisfying the rolling conditions of the process according to the invention have a coefficient ⁇ C more distant from C than the steels B, C, E. ⁇ r.
- steel B and steel H underwent similar conditions of hot rolling, cold rolling, annealing and cold rolling.
- steel H has higher yield strength and tensile strength values and above all a very lower ⁇ C and much more distant from 0.
- steel G has undergone a cold rolling rate of 86% and a re-rolling rate of
- the sheet or strip of very low carbon steel less than 0.008% and produced by the process according to the invention, that is to say with hot rolling, cold rolling with a reduction rate included between 83 and 92%, then recrystallization annealing at a temperature below Acl and finally cold re-rolling with a reduction rate of between 10 and
- 40% has a yield strength in the long direction between 350 and 450 MPa for a final thickness of approximately 0.22mm, between 440 and 540 MPa for a final thickness of approximately 0.20mm and between 500 and 600 MPa for a final thickness of approximately 0.18mm.
- the sheets or strips according to the invention can also be characterized in that the number of ferrite grains per mm 2 is between 10,000 and 30,000 and preferably between 15,000 and 25,000, this which corresponds to a very small grain size.
- the process for producing a sheet according to the invention also makes it possible to conserve a determined quantity of carbon in solution in the sheet.
- Such a sheet therefore has the characteristic of hardening significantly during the firing of the varnish, carried out on the box after it has been shaped.
- This characteristic is very important in the case of the manufacture of the boxes obtained by stamping-ironing because the sheet according to the method of the invention has the adequate mechanical characteristics to promote its shaping, the mechanical characteristics varying little over time. .
- This mechanical strength of the box is notably characterized by the turning pressure of the dome at the bottom of said box.
- This turning pressure increases by around 10% after baking, for example, for a given type of box, from 6.3 to 6.9 bars.
- the method according to the invention for the production of a sheet or a strip of steel with very carbcne case intended for the production of a box, of the drink box type, obtained by stamping-ironing makes it possible to reduce the thickness of the walls of the box and to obtain a weight gain of approximately 30% on the sheet or the strip, while increasing the drawing area and reducing the rate of horns and the risks of creases when the box is stamped.
