Zirkonya Filtresi<\/strong><\/p>\n

Ziroconia Filter has been widely used in the aluminum processing industry. There are two main modes in the application of deformed aluminum alloy melt purification technology.
\nIn-furnace fluxing and refining, semi-continuous casting of foamed ceramic plate filtration outside the furnace, ceramic filter plate replacement is one per casting, and some aluminum processing plants add a trough-type online deaerator before filtration to improve Purification effect.
\nThe second type is adopted on the continuous casting line, and the replacement is based on the pressure difference before and after the filter plate to determine the replacement period.<\/p>\n

Ziroconia Filter is a type of ceramic filter plate. The zirconia-based ceramic slurry is uniformly applied to the three-dimensional network structure and the organic foam of the communicating pores as a skeleton of the carrier, and then dried and solidified and then fired at a high temperature.<\/p>\n

Ziroconia Filter has a maximum temperature of 1760 \u00b0 C and is widely used in the filtration of various castings, high temperature master alloys and aerospace castings, magnetic materials, copper-magnesium alloy continuous casting and non-ferrous metal alloy low-pressure casting.<\/p>\n

Ziroconia Filter Porosity<\/strong>
\nPorosity is the percentage of the total volume of the cavities in the G\u00f6zenekli K\u00f6p\u00fck Seramik Filtre<\/a> product to the total volume of the filter plate product.
\nG\u00f6zeneklilik, birim hacim ba\u015f\u0131na k\u00f6p\u00fck seramik filtre plakas\u0131n\u0131n filtreleme kapasitesini belirler.
\nPorozite ne kadar y\u00fcksekse, filtre plakas\u0131n\u0131n filtrasyon ak\u0131\u015f h\u0131z\u0131 o kadar y\u00fcksek olur ve filtrasyon kapasitesi de o kadar g\u00fc\u00e7l\u00fc olur.<\/p>\n

\u015eu anda g\u00f6zeneklili\u011fi belirlemeye y\u00f6nelik iki temel y\u00f6ntem bulunmaktad\u0131r.
\nOne is to calculate the volume of the hole in the Ziroconia Filter according to Archimedes’ law, that is, to inject water into the glass beaker with the overflow pipe until the water flows out from the overflow pipe.
\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

The merits of Ziroconia Filter include:<\/strong>
\nReduce gas and inclusions that are contained in the casting, reduce the turbulence level of molten metal when filling the mold, reduce surface defects in castings, and significantly reduce the rejection rate of casting
\nIncrease the compressive sealing of casting, increase elongation and tensile strength of casting, improved surface finish of casting, improve the mobility of molten metal, increase the filling capacity and the feeding capacity of melt.
\nSimplify the casting system, reduce the length of the lateral flow channel, improve casting yield.
\nReduce the processing time and tool abrasion, improve surface quality of casting.
\nCeramic foam possesses high mechanical strength, chemical stability, high resistance to thermal shock and liquid metal flow shock even under high temperature environment.
\nNo slag or broken in working process, to ensure the quality and stable chemical composition of the molten metal.
\nHas a large and stable metal flow, even if the high content of inclusions in molten metals, ceramic foam filter will not be plugged.ery high dimensional accuracy, can be automatically placed in production line.<\/p>\n
