The usage of Foam Casting Aluminum grew continuously in metal casting process, for the reason that of the value added is greater than the cost of filter application and cost for purchasing filter. Whereas 20 years ago filter were used only in emergency cases but at present filter can be considered an integral part of casting.
\nThis is due to the advantages of the metal filtration which can be divided into three categories such as benefit to the foundry, benefits to the foundry`s customer and benefit to the final cast product.
\nSince 1976-2007 several efforts had been done to fabricate various ceramic foam filters in foundry industry include U.S.
\nLow expansion corrosion resistant ceramic foam filters for molten aluminum filtration 2007). Although all of the filters which have been fabricated in these patents have achieved acceptable ideal properties (high thermal shock resistance,adequate strength and low density), but none of them have been able to reach an acceptable price. Therefore the present research has been done to fabricate ceramic foam filter for filtration of aluminum alloy with new cheaper additives materials and improve a ceramic foam filter for using in filtration of molten metal, especially aluminium based alloys.<\/p>\n
Ar\u0131tma s\u00fcreci son derece \u00f6nemlidir; bu nedenle her cihaz\u0131n en iyi durumda olmas\u0131 gerekir.<\/p>\n
Metaller ve metal \u00fcr\u00fcnler, insan uygarl\u0131\u011f\u0131yla \u00f6zel bir ba\u011fa sahiptir. Bunlar, insan\u0131n kullanmay\u0131 ba\u015fard\u0131\u011f\u0131 ilk malzemelerden biri olarak kabul edilir. Ancak, t\u00fcm metaller en ham hallerinde \u00e7ok kararl\u0131 de\u011fildir. Metallerin bu hali, optimum metalik \u00f6zelliklere sahip olmayabilir ve bu nedenle ar\u0131tma gerektirir. Erimi\u015f metalin ar\u0131tma i\u015flemi, metal \u00e7\u00f6zeltisinden t\u00fcm safs\u0131zl\u0131klar\u0131n giderilmesini sa\u011flayan seramik k\u00f6p\u00fck filtreler gerektirir. Bu i\u015flem tamamland\u0131\u011f\u0131nda metal, farkl\u0131 s\u00fcre\u00e7ler arac\u0131l\u0131\u011f\u0131yla \u00e7e\u015fitli uygulamalarda kullan\u0131lmaya haz\u0131r hale gelir.<\/p>\n
S\u0131k\u0131\u015ft\u0131rma mukavemeti: Ar\u0131tma i\u015flemi s\u0131ras\u0131nda kullan\u0131lan hammadde miktar\u0131 olduk\u00e7a y\u00fcksektir; zira bu i\u015flemin k\u00fc\u00e7\u00fck miktarlarda ger\u00e7ekle\u015ftirilmesi maliyet a\u00e7\u0131s\u0131ndan verimli bir \u00e7\u00f6z\u00fcm de\u011fildir. Bu nedenle, bu filtrelerin \u00fczerine b\u00fcy\u00fck miktarda metalik \u00e7\u00f6zelti d\u00f6k\u00fcl\u00fcr ve filtrelerin i\u015flem s\u0131ras\u0131nda hasar g\u00f6rmeden dayanabilmesi i\u00e7in y\u00fcksek s\u0131k\u0131\u015ft\u0131rma mukavemetine sahip olmas\u0131 gerekir.<\/p>\n
Natural melting points of various metallic elements are very high. The range of melting point of metals may vary but generally is around few hundred to more than thousand degrees Celsius. It is therefore very necessary that Asian Foundry Filters must have certain properties. Here are some useful properties<\/p>\n
Porosity It is the percentage of the pore space in the Asian Foundry Filters. This property is very important in operations as a filter with much larger or smaller porosity can hamper the process. Therefore, it is recommended that porosity must be ideal in terms of the types of molten metal used.<\/p>\n
