Refractory Material Ceramic Foam Filter for temperatures up to 1250 \u00b0 C for filtration of aluminum and alloy solutions.
\nRefractory Material Ceramic Foam Filter To meet the ever-increasing quality of aluminum castings, the use of Seramik K\u00f6p\u00fck Filtre CFF<\/a> is becoming more and more important. Filters are also widely used in ordinary sand casting such as tidal casting and casting of permanent molds such as automotive aluminum parts casting.
\nRefractory Material Ceramic Foam Filter uses a filtration process based on the following considerations. On the one hand, the filtration makes the flow of aluminum liquid orderly and relatively calm, while on the other hand, the solid slag in the molten metal is effectively removed, and the quality of the casting is rapidly improved.<\/p>\n

Refractory Material Ceramic Foam Filter effectively removes solid inclusions from molten metal, so aluminum alloy can be smoothly forged, aluminum foil, and extrusion processes to obtain a perfect aluminum product.
\nThe product has a range of 20 ppi coarse pores to a very fine pore size of 60 ppi, so there will always be a product standard that suits your requirements. Both the normal size and the special size required by the customer can meet the requirements.<\/p>\n

\nInspect and clean the surface of filter bowl, keep it clean and intact.<\/strong>
\nGently lay the filter in the filter bowl, press sealing gasket around the filter by hand to prevent molten aluminum from dispersing or floating away.
\nUse electric or gas burning to preheat filter bowl and ceramic foam filter evenly for 15-30 minutes, make sure their temperature close to molten aluminum. The preheating temperature for ceramic foam filter should above 260\u2103. Expanding cotton will seal after preheating. This procedure makes ceramic foam filter steady fixed in molten aluminum. Preheating also leads ceramic foam filter pores open and avoid occlusion caused by thermal expansion and contraction.
\nObserve the change of molten aluminum height, hold molten aluminum flow in standard needs. Normal starting molten aluminum height is 100-150mm. The height falls down below 75-100mm when molten aluminum flows, and it will slowly increase later.
\nDo not hit or shake ceramic foam filter in filtration. At the same time, control molten aluminum flow rate in launder, never to be too much or too little.
\nTake out ceramic foam filter and clean filter bowl in time after filtering.<\/p>\n

\u015eu anda g\u00f6zeneklili\u011fi belirlemeye y\u00f6nelik iki temel y\u00f6ntem bulunmaktad\u0131r.<\/strong>
\nBunlardan biri, Ar\u015fimet yasas\u0131na g\u00f6re filtre plakas\u0131ndaki deli\u011fin hacmini hesaplamakt\u0131r; yani, su ta\u015fma borusundan d\u0131\u015far\u0131 akmaya ba\u015flayana kadar ta\u015fma borusu bulunan cam beher i\u00e7ine su enjekte etmektir.
\nSu art\u0131k d\u0131\u015far\u0131 akmad\u0131\u011f\u0131nda su tahlili yap\u0131lacakt\u0131r.
\nT\u00fcm numuneler suya dikkatlice yerle\u015ftirilir, ard\u0131ndan su ta\u015fma borusundan d\u0131\u015far\u0131 akar ve bu k\u0131s\u0131mdaki su hacmi \u00f6l\u00e7\u00fcl\u00fcr.
\nTa\u015fma suyunun hacmi, filtre plakas\u0131n\u0131n fiziksel hacminden \u00e7\u0131kar\u0131l\u0131r; bu hacim, filtre plakas\u0131ndaki deliklerin toplam hacmidir.
\nBa\u015fka bir y\u00f6ntem ise, test edilecek numunenin ger\u00e7ek yo\u011funlu\u011funu ve y\u0131\u011f\u0131n yo\u011funlu\u011funu ayr\u0131 ayr\u0131 belirlemek ve ard\u0131ndan a\u015fa\u011f\u0131daki form\u00fcle g\u00f6re numunenin g\u00f6zeneklili\u011fini hesaplamakt\u0131r.
\nBu iki y\u00f6ntemin kendine \u00f6zg\u00fc avantajlar\u0131 ve dezavantajlar\u0131 vard\u0131r.
\n\u00c7al\u0131\u015fma y\u00f6ntemi basit ve kullan\u0131\u015fl\u0131d\u0131r; alg\u0131lama h\u0131z\u0131 da y\u00fcksektir; ancak en b\u00fcy\u00fck zay\u0131fl\u0131\u011f\u0131, filtre plakas\u0131 malzemesinin kendisinin su emme \u00f6zelliklerinden kaynaklanmaktad\u0131r; bu nedenle tahliye edilen su hacmi, ger\u00e7ek hacimden daha azd\u0131r. Bu durum, \u00f6l\u00e7\u00fclen verilerin ger\u00e7ek de\u011ferden daha d\u00fc\u015f\u00fck \u00e7\u0131kmas\u0131na neden olur.
\n\u0130kinci y\u00f6ntemin test s\u00fcreci daha karma\u015f\u0131k olsa da, test s\u0131ras\u0131nda filtre plakas\u0131 malzemesinin su emiliminin etkisi ortadan kald\u0131r\u0131l\u0131r ve elde edilen veriler nispeten do\u011frudur.
\nBu standartta g\u00f6zeneklilik indeksi 84%\u2019den fazla olarak belirlenmi\u015ftir.<\/p>\n
