Factory Price Molten Metal Filtration Cordierite Ceramic Honeycomb Plate Foundry Filter for Casting¹

Product Description Cangzhou Sefu Ceramic New Materials Co., Ltd.Add: Guanting Industrial Park, Cangzhou City, Hebei, China Product DescriptionCeramic Honeycomb FilterCeramic honeycomb filters are mainly used in metallurgy and foundry industries. The product has the characteristics of a large surface area, high mechanical strength, and good thermal shock resistance. Its main materials are mullite, cordierite ceramics, Corundum-mullite, alumina, and so on. Mullite-based ceramic materials can withstand severe pouring thermal shock and extreme pouring temperature. The honeycomb design also provides an engineering balance between flow rate and strength. The honeycomb ceramic filter has precise dimensions, good thermal stability, high specific surface area, and excellent resistance to acids and alkalis. It is suitable for a wide range of filtration applications of ferrous and non-ferrous metal castings.By using Al2O3, it independently developed a pore filter with a pore density of 400 pores per square inch, compressive strength> 20 mPa, and porosity> 20%. The shape of this filter includes spherical, polygonal, and mesh partitions. Because this filter has strong corrosion resistance, high adsorption rate, no shedding, and enhanced durability, it has been favored by European and American customers for many years and is used as a carrier for desulfurization and denitrification catalysts in the petrochemical industry.Physical characteristics:Main material: Mullite, SiO2Working temperature: ≤1520oCWhite colorCSI (number of units per square inch): 50/100/200/300Porosity (%): 35-60Compressive strength (Mpa): ≥20 (room temperature)Bulk density (g/cm3): 0.8-1.2Thermal shock resistance: ≥2 times / 1100oC-normal temperatureSize: length (diameter) * width * thickness = (37-150) * (37-150) * (8-25) mmShape: circle, square and rectangleDimension tolerance: -1mm~1mmFeature:*Purify metal liquid, absorb oxides, and filter non-metal impurities*Make the metal liquid flow at a stable speed, reduce eddy currents, and reduce bubbles in the casting* Balance phase structure and extend tool life*Improve the surface properties of castings and increase the density of castingsGood thermal shock performanceThe uniform round holes avoid small eddies and turbulence when the molten metal passes through.The precise extrusion die makes the quality of the ceramic honeycomb filter extremely stable and consistentApplication range:*As a catalyst carrier, ceramic honeycomb materials are usually used to purify automobile emissions and eliminate odors.*As a heat exchange medium, ceramic honeycomb material is mainly used in the heat recovery unit of RTO, not ceramic saddle*Ceramic honeycomb material is used as the filtrate matrix, usually used in food processing, water treatment, environmental industry, metallurgical industry, etc.  ItemUnitAl2O3 CeramicAlumina Contentwt%99.7Densityg/cm33.90Bending StrengthMPa ≥450Working Temperature°C1800linear expansion coefficient×10-6/°C8.0Insulation strengthKv/mm12water absorption%<0.1-0.2Coefficient of Thermal ConductivityW/m·K( 20°C)38Molten Metal Filtration Cordierite Ceramic Honeycomb Plate Foundry Filter for CastingDetailed Photos Chemical and Physical Properties: Chemical PropertiesChemical compositionAL2O3SIO2MgOCaOK2O+Na2OFe2O3TiO235.1+-1.6%50+-1.8%13.5+-0.5%<0.5%<0.3%<1.0%<1.0%CrystallinityCordieriteMulliteCorundumPore capacity>93%<2.4%<1.2%0.12-0.3cm3/gPhysical PropertiesItemWater absorptionCoefficient of thermal expansionCompressive strengthIsostatic compressive strengthThermal shock resistancesoftening temperatureA axisB axisC axisData25+-4%<1.0x10-6/oC>10MPa>2MPa>0.11MPa>1.1MPA>650oC>1360oCCommon Sizes of honeycomb ceramic substrate for gasoline engine tail gas purifying system.
