【発明の詳細な説明】
本発明はアルミニウム―高珪素合金の鋳造法に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for casting aluminum-high silicon alloys.
アルミニウム―高珪素合金において、珪素はア
ルミニウム中にわずかしか固溶せず、しかも珪素
はアルミニウムと合金を作らないので初晶の形で
含まれている。珪素含有量が増すにつれて初晶の
粒子が大となり、強度が低下する。 In aluminum-high silicon alloys, only a small amount of silicon forms a solid solution in aluminum, and silicon does not form an alloy with aluminum, so it is contained in the form of primary crystals. As the silicon content increases, the primary crystal particles become larger and the strength decreases.
そこで珪素含有量の高いアルミニウム―珪素合
金の鋳造に際して、初晶珪素を30μ程度にまで微
細化するには、アルミニウム―珪素合金地金にリ
ンを0.01％程度含有させておく方法や、溶湯中に
赤リンないしはリン銅を添加する方法が採用され
ている。 Therefore, when casting an aluminum-silicon alloy with a high silicon content, in order to refine the primary silicon to about 30μ, it is necessary to add about 0.01% phosphorus to the aluminum-silicon alloy base metal, or to add phosphorus to the molten metal. A method of adding red phosphorus or phosphorous copper is adopted.
しかし、金型鋳造における溶解に際して、投入
材料に新塊地金のみを使用することは稀であり、
通常は戻り材も併せて使用する。この戻り材に含
まれるリンは、その初晶珪素の微細化機能が大幅

大化することが多く、安定した微細化を望めない
という欠点があつた。 However, when melting in mold casting, it is rare to use only fresh ingot as input material.
Usually, return material is also used. The phosphorus contained in this return material has a significantly reduced ability to refine primary silicon. For this reason, the primary crystal silicon in the cast product often becomes coarse, and stable refinement cannot be expected.
また、操業状態によつては、溶湯を長時間保持
するが、その場合、溶湯中のリンはその初晶珪素
の微細化機能が低下し、安定した微細化が望めな
い。溶解量に対して使用量が少ない場合にも、溶
湯は長時間保持されたと同様になる。 Further, depending on the operating conditions, the molten metal may be held for a long time, but in that case, the phosphorus in the molten metal deteriorates its ability to refine the primary crystal silicon, making it impossible to expect stable refinement. Even if the amount used is small compared to the amount melted, the molten metal will be held for a long time.
本発明は上記従来の方法の欠点を解消するべく
なされたもので、亜鉛めつき金網を通して注湯す
ることにより初晶珪素の微細化を行なうようにし
たアルミニウム―高珪素合金の鋳造法を提供する
ものである。 The present invention has been made to eliminate the drawbacks of the above-mentioned conventional methods, and provides a method for casting an aluminum-high silicon alloy in which primary silicon is refined by pouring the melt through a galvanized wire mesh. It is something.

のものとする。 The invention will now be described with reference to embodiments shown in the accompanying drawings. The figure shows an example of a hot water pump used in the casting method of the present invention, where 1 is a hot water pump and 2 is a galvanized wire mesh. The galvanized wire mesh 2 is generally commercially available and has a height about three times that of the hot water drawer 1.
亜鉛めつき金網２は図に示すように湯汲み１に
差し込まれる。 The galvanized wire mesh 2 is inserted into the hot water tap 1 as shown in the figure.

替えることができる。 During casting, the metal is poured through the galvanized metal mesh 2 from the pouring port 3. Since the part 2a protruding from the hot water tap 1 does not get hot, the galvanized wire mesh 2 is removed by holding this part 2a after pouring the hot water. After the galvanized wire mesh 2 has cooled down, the galvanized wire mesh 2 is inserted into the hot water pump 1 with the previously used part facing up and the unused part facing down. In this way, the galvanized wire mesh 2 can be replaced extremely efficiently every time the metal is poured.

節できる。 Since the metal is poured through the galvanized wire mesh as described above, zinc is uniformly inoculated into the molten metal, and the primary silicon is reliably refined during solidification of the alloy. The zinc and iron content of the poured casting increases somewhat, but according to experiments conducted by the present inventors, it was approximately 0.005%. When carrying out the present invention, the casting weight is preferably up to about 3 kg. Incidentally, the amount of zinc intake can be adjusted by changing the mesh of the above-mentioned galvanized wire mesh 2 or by using it in layers.
