40ppi Alumina Ceramic Filter for Filtration of Metal Alloys in Cast Houses

Product DescriptionAlumina ceramic foam filter is a trade description of low-density foundry filters,which are designed for filtration of aluminum and aluminum alloys.Ceramic foam filter plate is produced basing on carrier with solid reticular structure and combined organic foam pores. The producing procedure is as below, put carrier into the thixotropic alumina slurry, adopt square to center correcting automatic extrusion process, so that slurry evenly deposits in foam skeleton of carrier, after drying solidification, then carrier will turn into final product by roasting formed under 1180 ºC high temperature.The filters are placed into pre-developed chambers in inlet systems of the form or in sprue cups.They are suitable mainly for chill casting and for direct and indirect casting on a filter.Product Features1.High porosity2.Superior dimensional tolerances3.Low loss of thermal shock4.High mechanical strength at normal and high temperature5.Large specific surface6.Good chemical stability7.Excellent filtering functions of screen8.Excellent filtering residua collection and absorption9.Beveled edges and compressible gasket Product ParametersChemical CompositionAl2O3, SiO2Porosity(%)80~90ColourWhite Aperture10PPI-50PPIWorking Temperature≤1100°CBending Strength(Mpa) 0.6 Compression Strength(Mpa) 0.8 Thermal Shock Resistance  1100°C---room temperature 6 times Volume Density 0.4-0.5g/cm3Tolerance -1.0 / 0mm (also be customized according to customer requirements)Product SizeSpecification(inch)Filter Size(mm)Remark7 inches178*178*501.10-30ppi Aluminum alloy bar continuous casting and rolling2.30-50ppi for semi-continuous casting3.40-50ppi for high quality aluminium profile and plate4.50-60ppi for double zero wave continuous casting and rolling9 inches228*228*5012 inches305*305*5015 inches381*381*5017 inches432*432*5020 inches508*508*5023 inches584*584*5026 inches660*660*50Packaging & ShippingInside packing  Filters are put in small box         Outside packing 10 Small box put in one big carton.        Outside packing                                                                                 The mark on cartons can be designed according              Pallets: Export special pallets                                                                                 -to customer's request. Company Profile/* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
