Definitions
- the present invention relates to a method for composition of a metal product by the addition of at least one substance to this product.
- composition of a steel is always isotropic since the composition is carried out in the liquid phase of the metal. It is therefore impossible to produce "composite" steels with a core ductile and hard skin.
- the method proposed according to the invention provides a solution to these different problems.
- the composition steels after the solidification step allows working with standard compositions of very large volume at the steelworks, which allows to eliminate special casting and therefore to decrease strongly downgrading issues. It is even possible to produce very low tonnages of special steels.
- a method according to claim 1 which allows the composition of steels or other metals after solidification.
- the crystallization of a very low carbon steel followed by its composition is possible. This way of proceeding allows an improvement in mechanical properties compared to the case where the crystallization is obtained in the final composition.
- the process according to the invention is characterized by the fact that we make use of a metallic product in the form a continuous strip which is moved into a vacuum chamber, that we apply the substance on this tape and we broadcast this substance at least partially in the strip at the time it goes into the vacuum chamber keeping it at a temperature lower than its melting temperature, but high enough to allow this broadcast.
- the strip is preheated before the incorporation of the aforementioned substance.
- the contribution of the aforementioned substance in the strip is produced by sputtering technique, by vacuum evaporation technique, by arc deposition, by decomposition of a gas carrying this substance in a plasma or by a combination of two or more of these techniques.
- the invention relates to a process allowing the modification of the chemical composition of a metal in the solid state according to which use is made of a metal product in the form of a continuous strip that the we move to the parade in a vacuum chamber, in which prevails for example a total gas pressure of 0.13 to 1 ⁇ 33 Pax10 4 Pa (10 -4 to 100 Torr) and in which we create a plasma, opposite a or of its two faces, so as to introduce into said strip, for example by bombardment and / or diffusion, a determined substance present in this chamber.
- This strip is heated and kept at a temperature high enough to allow at least the partial diffusion of this substance in the strip. This temperature is, however, lower than the melting temperature of the material from which the strip is made.
- the strip can, for example, be a strip of mild steel, stainless steel or aluminum.
- the strip is preferably maintained at a temperature of the order of 600 to 1200 ° C., while in the case of aluminum, this temperature is generally of the order of 200 ° to 600 ° C.
- we preheat advantageously the strip and the above-mentioned substance is incorporated before or after an annealing step by means of formed discharges by plasma.
- the attached figure shows an annealing installation in which the composition according to the invention can be carried out a metal strip, which is preferably made of a sheet of steel, moving substantially continuously through a vacuum chamber 2 of this installation in which the annealing by plasma discharges.
- the discharges are established between sheet 1, during its passage through a first zone 10 of this chamber 2, and a counter electrode 3 in such a way as to dissipate electrical power from the discharges in this sheet 1 and thus therefore to create the annealing.
- the plasma can be created in direct current, the sheet forming then the cathode, or alternating current.
- a counter electrode 3 extending into the vacuum or annealing chamber 2, facing the sheet 1, and having a surface directed towards the sheet, the surface of which is greater than that of the part of the sheet facing it, in order to maintain a negative self-polarization of the latter.
- the discharge can possibly be carried out in presence of magnetic induction fields thanks to the presence magnets 5 near the sheet 1 and on the opposite side thereof by compared to the counter electrode 3.
- the power densities dissipated per face on the steel sheet 1 are typically between 1 W / cm 2 and 500 W / cm 2 , while the running speeds of this sheet are generally between 1 m / min and 1500 m / min.
- the temperature rise takes place in the sheet metal area where power dissipation takes place, while the rate of rise in temperature depends on the adaptation of the power density used, line speed as well as the thickness of the sheet and its heat capacity.
- a temperature stabilization in the annealing cycle can, for example example, be obtained by providing in the vacuum chamber 2 a area where the sheet runs freely under reduced pressure. It is enough, by example, in such a case, to provide a compartment 6, somewhat isolated from zone 10, where warming takes place through the creation of plasma.
- a temperature stabilization in the annealing cycle.
- the contribution of the aforementioned substance can be obtained in zone 10 by any deposit system under vacuum indicated schematically by reference 8, such as by sputtering by ions from a target not shown or evaporation under vacuum, by arc deposition, or more generally by any PVD deposition technique ("physical vapor deposition"), or by PECVD ("plasma enhanced chemical vapor deposition ”) i.e. by decomposition of a gas carrier of the substance in question, which is, for example, injected into plasma, as shown schematically by arrows 9 on the Fig.
- any deposit system under vacuum indicated schematically by reference 8 such as by sputtering by ions from a target not shown or evaporation under vacuum, by arc deposition, or more generally by any PVD deposition technique (“physical vapor deposition"), or by PECVD (“plasma enhanced chemical vapor deposition ”) i.e. by decomposition of a gas carrier of the substance in question, which is, for example, injected into plasma, as shown schematically by arrows 9
- the injection of the substance can be carried out in the holding zone 6 of the temperature in which one can possibly create a discharge.
- the process according to the invention generally comprises a step of raising temperature obtained by the heat losses of the plasma 4 produced at the strip 1, a temperature maintenance step in compartment 6 where the strip 1 is arranged in an accordion.
- Example 1 Composition of a support for tinplate.
- the basic steel has the following composition: C: 0.035%; N: 0.0025%; Ti: 0%; Mn: 0.4%; B: 0%; Al: 0.04%.
- the strip width is 1000 mm and its thickness is 0.2 mm.
- the inlet temperature of the heating zone 10 is 20 ° C. and that of the entry from the zone 10 into the holding zone 6 is 800 ° C.
- the temperature rise is carried out by a plasma over a length of sheet metal of 7 m with a consumed power of 10 MW.
- a reactive mixture consisting of 90% nitrogen and 10% C 2 H 2 is injected into the discharge.
- the decomposed gas is then entrained towards the temperature maintenance zone 6.
- the total gas pressure is 0.02 Torr. After this step, constituting in fact a reactive annealing, the sheet is cooled and tinned.
- the average final carbon and nitrogen composition of the sheet thus cooled is 0.06%.
- Example 2 Composition of a boron steel.
- a sheet of ULCTi ("Ultra Low Carbon Carbon Ti”) steel 1 mm thick is used, the composition of which is as follows: C: 0.003%; N: 0.0025%; Ti: 0.06%; Mn: 0.15%; B: 0%; Al: 0.04%.
- This strip continuously enters the installation at a line speed of 200 m / min.
- the strip width is 1000 mm.
- Heating takes place over a strip length of 10 m and the applied power is 10 MW, so as to reach 800 ° C before entering compartment 6.
- a deposit of boron is carried out on the surface of the sheet beforehand annealing by vacuum evaporation at a rate of 0.04 g / m 2 of boron per side.
- the temperature holding zone corresponds to 200 m from length of the sheet.
- the final boron composition of the sheet at the outlet of the installation is 0.001% and that of the other elements has remained unchanged.
