Abstract
Description
Vynález se týká kovové přísady pro hliník a jeho slitiny.The invention relates to a metal additive for aluminum and its alloys.
Jsou známy kovové přísady pro hliník a jeho slitiny, které zahrnují jemně práškovou přísadu, například mangan, železo, měď, nikl. Nevýhodou dosavadních známých kovových přísad je, že se jimi nedosahuje uspokojivých rychlostí jejich rozpouštění.Metal additives for aluminum and its alloys are known which include a finely powdered additive, for example manganese, iron, copper, nickel. A disadvantage of the known metal additives of the prior art is that they do not achieve satisfactory dissolution rates.
Nyní bylo zjištěno, že přidáním jemně práškového hliníku к jemně práškové kovové přísadě se výrazně zlepší postup rozpouštění přísady v lázni roztaveného hliníku nebo v lázni jeho slitin.It has now been found that the addition of finely powdered aluminum to a finely powdered metal additive significantly improves the process of dissolving the additive in a bath of molten aluminum or a bath of its alloys.
Jsou proto předmětem vynálezu kovové přísady pro hliník a jeho slitiny, zahrnující jemně práškovou přísadu, například mangan, železo, měď nebo nikl, jejichž podstata spočívá v tom, že ke snadnějšímu průběhu vytváření slitiny je ke kovové přísadě přidán jemně práškový hliník, v hmotnostním poměru až 90 hmotnostních % jemně práškové přísady na až 10 hmotnostních % jemně práškového hliníku.It is therefore an object of the invention to provide metallic additives for aluminum and its alloys, including a finely powdered additive, for example manganese, iron, copper or nickel, characterized in that finely powdered aluminum is added to the metal additive to facilitate the alloying process. up to 90% by weight fine powder additive to up to 10% by weight fine powder aluminum.
Takto sestavené kovové přísady umožňují snadnější, rychlejší a dokonalejší průběh vytváření slitiny.The metal additives thus assembled allow for easier, faster and more perfect alloys.
Vnesení jemně práškového legujícího prvku, smíšeného s jemně práškovým hliníkem, umožňuje rychlé rozpouštění přísady. Aby se dosáhlo optimální rozpustnosti, mají mít částice takový rozměr, aby prošly sítem majícím 20 ok na 25,4 mm s výhodou sítem majících 65 ok na 25,4 mm.The introduction of the finely-powdered alloying element mixed with the finely-powdered aluminum allows for rapid dissolution of the additive. In order to achieve optimal solubility, the particles should be sized to pass through a 20 mesh / 25.4 mm sieve, preferably a 65 mesh / 25.4 mm sieve.
Přísada se vnáší do lázně roztaveného kovu zabalená v kovové fólii nebo se přidává v obalu. Nejčasněji a nejvýhodněji se však přísada přidává v podobě slisovaných tělísek nebo pelet, které mají dostatečnou hustotu. Je třeba se vystříhat hustotám nad 95 % maximální teoretické hustoty.The additive is introduced into a molten metal bath wrapped in metal foil or added in a wrapper. Most preferably, however, the additive is added in the form of compacted bodies or pellets having a sufficient density. Densities above 95% of the maximum theoretical density should be avoided.
Vynález je blíže objasněn dále uvedenými příklady.The invention is illustrated by the following examples.
Příklad 1Example 1
Lázeň 2,27 kg roztaveného hliníku se stabilizuje při teplotě 850 °C a přidá se 34 g (tj. 1,5 %, vztaženo na hmotnostní množství roztaveného hliníku) manganu jakožto šupinek elektrolytického manganu. Za 15 minut se rozpustí více než 1,12 % manganu.A bath of 2.27 kg of molten aluminum is stabilized at 850 ° C and 34 g (i.e. 1.5% by weight of molten aluminum) of manganese is added as flakes of electrolytic manganese. More than 1.12% of manganese is dissolved in 15 minutes.
Příklad 2Example 2
Opakuje se postup z příkladu 1, přičemž se však jako přísady použije pelet obsahují199224 cích například · 90 hmotnostních % manganu a 10 ' hmotnostních . % hliníku. Pelety · se získají · slisováním promísené směsi práškového hliníku · a práškového manganu v uvedeném hmotnostním poměru. Rychlost . rozpouštění manganu je velmi vysoká a využití manganu je více ' než 95%ní.The procedure of Example 1 is repeated except that pellets containing, for example, 902% by weight of manganese and 10% by weight are used as additives. % aluminum. The pellets are obtained by compressing the mixed mixture of aluminum powder and manganese powder in the weight ratio indicated. Speed. the dissolution of manganese is very high and the utilization of manganese is more than 95%.
