Definitions
- the present invention relates to a cold-worked steel plate aluminum, intended for the manufacture of packaging and a process for manufacture of packaging, having for application the field of packaging metallic, food, non-food or industrial.
- Beverage box type packaging is produced by implementation of steel sheets, and we generally distinguish two-piece packaging consisting of a bottom and a body, comprising a side wall and a bottom, and three-piece packages consisting of an electrically welded body and of two funds.
- the thicknesses of the steel sheets for packaging vary from 0.12 mm to 0.25 mm for the majority of uses, but may reach greater thicknesses, up to 0.49 mm for very large applications special. They can also go down to 0.08 mm, for example in the case of food trays.
- Packaging companies are showing an increasing interest in steels of ever smaller thicknesses, from 0.12 mm to 0.075 mm and, in the concern to differentiate themselves from competitors, they seek to innovate in increasingly complex forms.
- There is therefore a demand for boxes of original shapes, made with thin steel sheets which, although having greater forming difficulties, must respond to the criteria of use which are in particular the mechanical strength of the packaging, the resistance to the axial load which they undergo during their stacking storage, the internal overpressure resistance they undergo during sterilization heat treatment and depression they undergo after cooling.
- the steel sheets must therefore have a very high tensile strength Rm, and good ductility.
- the object of the present invention is therefore to remedy the disadvantages of the sheets of the prior art by providing a sheet for manufacturing steel packaging with good mechanical strength and good ductility, and whose physical properties have a low dispersion.
- a first object of the invention consists of a sheet work hardened in steel quenched in aluminum, comprising by weight between 0.003 and 0.130% carbon, between 0.10 and 1% manganese, between 0.010 and 0.100% aluminum, between 0.0015 and 0.0140% nitrogen, the rest being iron and impurities resulting from processing, and in that it includes a content of carbon in solid Css solution of at least 50 ppm.
- the present inventor has noted in particular that there is a threshold of carbon content in solid solution in the sheet steel before setting work, beyond which the mechanical characteristics of the packaging produced with these sheets vary little.
- the sheets of art carbon containing solid solution have values up to 15 to 30 ppm maximum.
- a sheet which achieves the TH720 (DR10) quality with an elastic limit greater than 700 MPa, after work hardening.
- a second object of the invention is constituted by a method of manufacture of an aluminum calm steel packaging, including the step consisting in subjecting a cold-worked steel plate to shaping at aluminum, according to the invention, and optionally comprising a treatment thermal of said shaped sheet.
- the shaping of the sheet is a stamping operation.
- the shaping of the sheet is a deep drawing operation followed by ironing.
- the carbon content targeted in the context of the present invention is between 0.003% and 0.130%.
- carbon in a second embodiment, we prefer contents in carbon between 0.060% and 0.080% by weight. Carbon content is chosen greater than 0.060% to obtain a sheet having a greater hardness. However, the carbon content is limited to 0.080%, because beyond this observes difficulties with cold rolling.
- the manganese content targeted in the context of the present invention is between 0.10% and 1%.
- the manganese content is between 0.15 and 0.50% by weight, which allows to obtain less hard sheets.
- the manganese content is between 0.35 and 0.50% by weight, which increases the aging tendency of the sheet.
- the nitrogen content targeted in the context of the present invention is between 0.0015 and 0.0140% by weight of nitrogen. We prefer however limit the nitrogen content between 0.0020 and 0.0060% in order to avoid too much hardening of the steel by this element, which would degrade the cold rollability.
- the steel sheets to be shaped by the process according to the invention can be obtained by any suitable method.
- the main factors involved in defining the rate of cold reduction are the final thickness of the product, as well as the incidence of rate of cold reduction on the microstructural state, and consequently on the mechanical characteristics after recrystallization and annealing. So more the cold reduction rate increases, the higher the recrystallization temperature is weak, the weaker the grains and the higher Re and Rm. In in particular, the reduction rate can have a very strong impact on the Lankford coefficient.
- the sheets can then be annealed and cold-worked with a skin-pass with a variable elongation rate between 0.2% and 45% depending on the level of tensile strength Rm or the elastic limit targeted.
- the annealing cycles used for these steels for packaging are constructed based on the Mohri annealing cycle which includes three phases of a duration of about 20 seconds and which breaks down into a phase of heating to reach the holding temperature, then a phase of hold, followed by a cooling down to temperature room.
- the sheets to be shaped by the method according to the invention must however contain a minimum quantity of carbon in solution solid after annealing. Such a result can in particular be obtained by now carbon in solid solution, by cooling fast enough after the high temperature maintenance phase.
- maintaining carbon in solid solution can be obtained with cooling rates between 7 and 600 ° C by second.
- the sheets are subjected to work hardening at a rate 5% elongation, followed by an aging treatment of 20 minutes at 200 ° C.
- the carbon content in solid solution of these sheets is determined either by measuring the internal friction coefficient, or by measuring the thermoelectric power according to a conventional protocol.
- Another characteristic of the three series of sheets is their content nitrogen in solid solution.
- the A series does not contain any, while the B series does contains 50 ppm and the C series contains 100 ppm. We see that this nitrogen in solid solution has no action on the dispersion of the elastic limit of sheets, above the 50 ppm carbon threshold in solid solution.
- composition A comprising 52 ppm carbon in solid solution, and, following annealing similar to that described in point 1., one subjects them to a work hardening whose rate SP elongation is variable.
