Definitions

  • the present invention refers to a procedure for the manufacture of high concentration manganese (Mn) minitablets for aluminium (Al) bath alloying, the purpose of which is to produce Mn minitablets with a 90-98% concentration of this metal, for adding in Al smelting.
  • Mn manganese
  • Al aluminium
  • the object of the invention is to produce a minitablet product composed of Mn and Al powder whose first component is obtained by electrolysis and grinding, while the second component is an atomised powder produced by means of mechanical processes, both components being them mixed and compacted to form minitablets with a high Mn concentration.
  • a further object of the invention is the device for the execution of the above-mentioned procedure, the device where the loading, dispensing, compacting and final forming of the minitablets take place.
  • the pellets consist of Mn powder in a concentration usually above 75% compacted using Al powder as the binding agent, a flux, or a mixture of both, in a concentration of up to 25%. These materials substantially reduced the amount of cold material which is added to the Al furnace in the alloying operation in comparison with parent alloys. Furthermore, parent alloys usually contain 75 to 90% second smelting aluminium, which could give rise to problems in the molten metal, besides calling for a stock 4 times higher than that of compacted powder alloying agents. Moreover, they are easy-to-use materials that do not require the investment in equipment and safety that is necessary for powder injection.
  • the decreased Al content brings a series of advantages for the founder.
  • the amount of material to be added to the furnace is smaller, which means that less cold material is added to the Al bath and that raw material stocks are reduced.
  • there is a cut in material transport costs which will be significantly lower than those of 75% or 80% compacts.
  • the price of products depends less on the value of Al, subject to the changes in its quotation on the London Metal Exchange, and since Al is currently more expensive than Mn, the cost of the set of the raw materials used in production would also be lower.
  • the present study concentrates on the flow production and performance in the Al furnace of alloying minitablets (cylindrical in shape) containing Mn in a concentration of more than 90%, Al being the remaining material. Although it would be desirable to have this concentration available in standard sized tablets as well, the need to apply high pressures to the material means that the study is complicated if the size of the compact diameter is larger than 40 mm. On the other hand, fluxes were initially rejected in this study insofar as they are materials whose binding action is considerably inferior to that of Al powder.
  • Mn is the first limitation of the study.
  • the chemical requirements of Al baths involve the use of Mn of a high chemical purity, usually above the 99.7% level, which can only be assured if the Mn is produced by electrolysis.
  • electrolytic Mn is only produced in the Republic of South Africa and the People's Republic of China, which reduces the possibilities of finding materials with different specifications.
  • Mn which is usually in flake form, has to be converted into powder by grinding.
  • the material normally used in the compacting of Mn minitablets has a grain size of less than 450 microns.
  • Mn powder is highly abrasive, a property that is enhanced if the amount of fines (powder below 100 microns) increases, and which has a direct effect on the pressing quality and the average life of the materials (punches and liner) of the press in which the material is compacted.
  • the Al used in the production of Mn minitablets is a gas-atomised powder, although materials may be used that are obtained by mechanised atomisation procedures, annealed materials or micronised swarf.
  • atomised powders are the most suited to the requirements of the main functions of Al.
  • Mn minitablets with a concentration of more than 90% should be compacted by using Mn produced by electrolysis and ground from flakes of Mn of a chemical purity of 99.7% or more, which is subjected to a screening process with a sieve with a mesh of less than 450 microns;
  • the special feature of the Mn grinding process is that it is controlled so that the content of fine Mn powder, with a size of less than 100 microns, should not be more than 15%, as above this proportion the compacting of Mn minitablets cannot be assured with over 90% Mn in their composition.
  • the procedure also includes the fact that the most suitable Al for successfully compacting Mn minitablets is atomised powder, which is produced by mechanical processes, with controlled size distribution, its nominal grain size intervals being between 100 and 800 microns, with over 80% of the powder in the 350-720 micron range.
  • This grain size distribution is coarse enough to enable the material to be compacted and fine enough not to retard the dissolving rate, through having reduced the number of Al grains with the increased Mn concentration in the minitablet.
  • the invention also refers to the device for executing the foregoing procedure, consisting of a hopper for the reception of an Mn and Al mix with the afore-mentioned characteristics, there being a central product diffuser in this hopper which forces the product to flow through the sides of the hopper to prevent the mix directly reaching the feeder of a second hopper which discharges into the respective pressing or compacting chamber, where pressing punches will come into action.
  • the device has appropriate means that enable maximum, minimum and safety levels to be kept under control in the compacting chamber so that it remains at a level of filling all the time such that none of the punches may try and make an off-load compacting stroke.
  • the device includes a honeycomb dispensing valve interposed between the feed hopper and the compacting chamber, which is provided with a series of dies that are mounted on a support integral with the actual feed hopper, so that the support-hopper assembly is able to run along guides, in either direction, under the action of a pneumatic device, on which guides there is in turn a moving punch support mounted, also driven by a pneumatic ram, so that the support-hopper movement is independent of the moving punch movement, although such movements must be synchronised in order to fill, press, compact and eject the formed minitablet.
  • a honeycomb dispensing valve interposed between the feed hopper and the compacting chamber, which is provided with a series of dies that are mounted on a support integral with the actual feed hopper, so that the support-hopper assembly is able to run along guides, in either direction, under the action of a pneumatic device, on which guides there is in turn a moving punch support mounted, also driven by a pneumatic ram, so that the support-hopper movement is independent of
  • the device also includes three electrical control means to monitor the maximum, minimum and safety levels, corresponding to compacting chamber filling.
  • the invention procedure designed to produce Mn minitablets by compacting, with a concentration of more than 90% of this metal, is based on using electrolytic Mn ground from flakes of a chemical purity of 99.7% or more.
  • the product is then screened with a sieve with a mesh of less than 450 microns, since it has been found that materials containing significant fractions of a larger grain size give rise to much lower dissolving rates in the aluminium furnace.
  • the grinding process is controlled so that the content of Mn fine powders (below 100 microns) is more than 15%, as above this percentage it has been found that the compacting of minitablets cannot be assured with more than 90% Mn in its composition.
  • Figure 1 shows the graph referring to the standard grain size distribution of the Mn used.
  • the foregoing Al powder also has a controlled grain size distribution, its nominal grain size intervals being between 100 and 800 microns, with over 80% powder between 350 and 720 microns.
  • This grain size distribution is coarse enough to enable the material to be compacted and fine enough not to retard the dissolving rate, through having reduced the number of Al grains (which trigger the dissolving reaction on the minitablet Mn in the furnace) with the increased Mn concentration in the minitablet.
  • Figure 3 shows the graph referring to the standard Al grain size distribution in the grains used.
  • the device for executing the procedure is represented in figures 4 and 5, comprising a hopper (1) for reception and storage of the mix, which is fed in through the respective filler neck (2), a mix which, as stated, is composed of Mn and Al.
  • the mix has to be homogeneous and, on being received in the hopper (1), it falls on a centrally positioned diffuser (3), a diffuser (3) that has a conical layout and is supported on legs (4), so that this diffuser forces the product to flow through the sides of the hopper (1) and never directly onto the feeder hopper (5) provided at the outlet of the hopper (1), and from which hopper (5) the product moves onto the compacting hopper (6).
  • the diffuser (3) prevents the effects of product separation and assures continuous fluidity at the same level of product in the hopper (1).
  • the compacting hopper (6) is a vertical continuation of the feeder hopper (5), so that the former defines a chamber which maintains a product level and in which the compacting is done by means of both fixed punches (7) and moving punches (8).
  • the compacting hopper (6) is provided with a series of dies (9), of varying number depending on the size of the device, and the product or Mn and Al powder reaches these dies (9) by way of a honeycomb valve (10) interposed between the feeder hopper (5) and the compacting hopper (6), so that a metered amount of product passes through this valve and is loaded onto each one of the dies (9), as the honeycomb valve (10) forms a sort of drum-sector that is loaded with a given quantity of product so that, when this valve turns through an angle, the corresponding sector load discharges on the compacting hopper (6) and the product reaches the respective die (9).
  • a honeycomb valve (10) interposed between the feeder hopper (5) and the compacting hopper (6), so that a metered amount of product passes through this valve and is loaded onto each one of the dies (9), as the honeycomb valve (10) forms a sort of drum-sector that is loaded with a given quantity of product so that, when this valve turns through an angle, the
  • the dies are arrayed on a support (11) which is integral with the actual compacting hopper (6), and that support-hopper assembly is mounted on guides (12), along which it may move in either direction under the action of a pneumatic device, on which guides (12) there is in turn a moving punch (8) support (13) mounted, also driven by a pneumatic ram or device.
  • the support-hopper movement is independent of the moving punch movement, although such movements must be synchronised in order to fill, press, compact and eject the formed minitablet.
  • the fixed punches (7) are arranged co-axially facing the moving punches (8), the latter being installed on a static support (14).
  • this device It is essential for this device to maintain a minimum product column level in the compacting chamber (6), so that none of the punches attempts to compact an empty die, which would result in the breakage of the punches and column or chamber.
  • This level is maintained by the use of three electrical controls and the afore-mentioned honeycomb valve (10), controls which correspond to references A, B and S, and which indicate the maximum level, minimum level and safety level of the product in the compacting chamber (6), all of this in such a way that the safety level S causes the device to shut off if the product drops below this level because there will be a risk of emptying the chamber, whereas level B is the product level that permits a reproducible column weight to be maintained capable of assuring suitable fluidity and consistent reproducible filling at all the punches.
  • the honeycomb valve (10) opens and dispenses more product from the hopper. This honeycomb valve (10) closes when the product reaches the maximum level A.
