Definitions
- the invention relates to a process for the production of aluminum-silicon alloys, more particularly alloys with more than 7% silicon, by introducing silicon metallurgical in liquid aluminum.
- Silicon is a fairly common addition element in aluminum alloys, in particular Al-Si-Mg alloys (6000 series) and Al-Si alloys (4000 series). In this last category of alloys, used mainly for the manufacture of molded parts, the content in silicon can be important, and sometimes exceed the content of the eutectic, which is around 13%. These alloys can contain other elements of addition such as magnesium, copper, manganese, zinc or nickel.
- this final addition is in the form of silicon obtained from ingots, of mass always greater than 10 kg, crushed then crushed to obtain pieces of less than 10 mm, and, after sieving to 1 mm, a product of grain size 1-10 mm.
- the object of the invention is a process for the production of alloys of the Al-Si type, in particular alloys between 7 and 13% silicon, in a flame or induction furnace, allowing a rapid dissolution of silicon, a reduction in the number of bath stirrings and a lesser formation of dross.
- the subject of the invention is a process for the preparation of Al-Si alloys by introduction into liquid aluminum, at a temperature between 700 and 850 ° C, of silicon grains metallurgical material with a particle size of less than 10 mm, in which the silicon grains, when they reach the temperature of liquid aluminum, have the property of fragmenting into smaller grains.
- the metallurgical silicon grains used are prepared by granulation at water from molten silicon.
- the invention is based on the finding made by the plaintiff of different behavior, during the development of aluminum-silicon alloys, between the silicon usually used and obtained by casting ingots, crushing and grinding, and the silicon obtained by granulation at the water.
- the latter under certain conditions of use, makes it possible to reduce both the duration of dissolution of silicon in liquid aluminum, and losses of metal by oxidation.
- Water-granulated metallurgical silicon is used for the synthesis of halosilanes which are used for the preparation of silicones, as indicated in patents EP 0610807 (Wacker Chemie) or EP 0673880 (Pechiney Electrométallurgie).
- a water granulation process of silicon is described for example in patent FR 2723325 (Pechiney Electrométallurgie).
- a first difference concerns the content of fine particles.
- sieving a powder to extract the fraction below 50 ⁇ m is almost ineffective in removing the most fines, for example the fraction less than 5 ⁇ m.
- These very fine particles are probably generated during product packaging and observation of the powder under a microscope confirms existence.
- the assessment of their relative mass quantity can be determined by laser particle size. We always find in the size range 1-10 mm of silicon prepared by the dry route, mass fractions of particles of size less than 5 ⁇ m of the order of at least 0.5%.
- the method of preparation can be used of the product to insert into the process a step of rinsing with water which makes it possible to eliminate the most of the particles smaller than 5 ⁇ m.
- We can thus obtain a granule containing less than 0.1% of particles smaller than 5 ⁇ m, or even less than 0.05% by performing two successive rinses.
- the levels of particles less than 50 ⁇ m and 5 ⁇ m respectively remain practically unchanged after its subsequent rise in metal temperature liquid.
- the bursting of the grains does not concern only a few grains of granulated silicon, but the majority of them, which excludes the explanation of a sudden volatilization of inclusions of water incidentally present in some of these grains.
- the granulation with water of liquid silicon can give products whose particle size is between 0 and 30 mm, it is necessary to select from silicon granulated, by sieving for example, a finer grain size, limiting itself to the slice less than 10 mm.
- the method according to the invention makes it possible to obtain Al-Si alloys of a quality at least as good as those prepared with crushed and ground silicon.
- the inclusion quality of the alloys is at the same level, the number of inclusions detected in the alloy not varying significantly.
- the hydrogen contents measured on the liquid alloy are of the order of 0.1 to 0.2 cm 3 of hydrogen per 100 g of alloy. When adding silicon, these contents vary by plus or minus 10% whatever the type of silicon used, which confirms that the granulated silicon does not constitute a significant supply of hydrogen.
- the inclusion quality control of the liquid metal was made by K-Mold and LIMCA (Liquid Metal Cleanliness Analysis) tests whose object is to quantify the concentrations of oxide inclusions through results expressed in units specific to each of these tests.
- the K-Mold test consists of counting the number of inclusions detected on the fracture surface of a test piece poured into a mold of defined shape. The results are expressed in number of inclusions reduced to the fracture surface of the test piece. This test can detect large inclusions, typically in the 50 ⁇ m - 300 ⁇ m range.
- LIMCA control implements hardware related to the Coulter Counter and allows to evaluate the concentration in the metal of solid inclusions of size between 20 ⁇ m and 150 ⁇ m; the results are expressed in number of inclusions per kg of metal.
- the observed values can range from 1000 inclusions per kg for a alloy considered clean at 100,000 inclusions per kg for a very dirty alloy.
- the hydrogen content is checked by means of an ALSCAN device which allows immediate measurement on the liquid alloy.
- the results are expressed in cm 3 of hydrogen gas, brought under normal conditions of temperature and pressure, per 100 g of alloy.
- This production was ground to a maximum particle size of 10 mm, then sieved to 1 mm to separate the fraction 1-10 mm. To assess the particle size quality of this product, a sample was taken and then washed with water.
- the washing water was then evaporated to collect the fine entrainments which were analyzed. by means of a laser granulometer. We were able to reconstruct the real analysis particle size of the original product, which was found to contain 0.51% size fines less than 5 ⁇ m.
- the operations carried out consisted of going up by 1 point the silicon content of Al-Si alloys with 0, 6 and 12% Si respectively. These operations were carried out in an electric resistance furnace, at 750 ° C, on crucibles of 100 kg of alloy.
- the second batch of ground silicon prepared in Example 1 was used during a workshop test of manufacture of alloy A-S13 for placing under the bath before casting.
- the operation was performed in a 5 ton flame oven whose temperature was regulated with as 750 ° C set point.
- 245 kg of product were added, and between at the time of this addition and the final pouring, 47 minutes have passed.
- Two brews of bath were carried out and at the end of the operation 16 kg of slag were recovered.
- Example 1 The third batch of ground silicon prepared in Example 1 was used to repeat the experiment in Example 1 by controlling the oven temperature to 810 ° C. The times required for the dissolution of the silicon additions were 8 to 10 minutes, which allowed to assess at about 20% the gain due to the effect of the temperature rise.
- the metal yield was estimated at 96%.
- Example 1 The fourth batch of ground silicon prepared in Example 1 was used during a workshop test of manufacture of alloy A-S13 for the setting under the bath before casting. The operation was performed in a 5 ton flame oven whose temperature was regulated with as set point 810 ° C. For the title, 179 kg of product were added, and between at the time of this addition and the final pouring, 28 minutes have passed. We did two bath mixes and at the end of the operation 12 kg of slag were recovered.
- a test for the production of granulated silicon was carried out on the same industrial installation than that which was used to prepare the ground silicon of Example 1, without changing or charging the silicon oven, nor the operating conditions of the treatment in bags for refining.
- the contents of a ladle of molten silicon at 1530 ° C was poured onto an installation of water granulation in tanks.
- the product recovered in the granulation pool was rinsed with water sprayed before being dried and then sieved to 10 mm.
- the fraction greater than 10 mm has been eliminated and assigned to other applications. No 1 mm sieving was done.
- the 0/10 mm granule obtained was subjected to a particle size control in the same conditions as in Example 1.
- the rate of fines smaller than 5 ⁇ m was 0.03%.
- the metal thus prepared was separated into two identical batches, one of which was used in the workshop tests for an Al-Si alloy bath before casting.
- the operations carried out consisted of raising the silicon title by 1 point of Al-Si alloys with 0, 6 and 12% Si respectively. These operations were carried out in a resistance furnace, at 750 ° C, on crucibles of 100 kg of alloy.
- the second batch of granulated silicon prepared in Example 5 was used during a workshop test for manufacturing alloy A-S 13 for placing under the bath before casting.
- the operation was performed in a 5 ton flame oven whose temperature was regulated with as set point 810 ° C.
- 256 kg of product were added.
- the merger and mixing this addition was very quick; only one bath brewing was carried out and the pouring started only 19 minutes after the addition of silicon.
- At the end of the operation only 3.5 kg of slag was recovered.
