Product DescriptionProduct DescriptionHigh-Performance Silicon Carbide Ceramic Filter PlatesSilicon carbide foam ceramic filters have the characteristics of high strength, good thermal stability, large specific surface area and high dimensional accuracy. Mainly used for filtration of ductile iron, gray iron, copper and other castings, effectively removing large inclusions in molten metal and adsorbing small Impurities, reduce the content of gases and harmful elements in molten metal, improve the metal matrix structure, and improve the mechanical properties of castings.SpecificationSilicon Carbide Ceramic Filter AdvantagesOutstanding high-temperature resistance: It can operate stably for a long time at ultra-high temperatures above 1500°C. High strength and wear resistance: It features extremely high hardness and mechanical strength, and has excellent resistance to erosion and wear. Excellent chemical stability: It does not undergo chemical reactions with molten metals, effectively preventing secondary pollution. High-efficiency filtration performance: The three-dimensional mesh structure can more effectively capture and adsorb impurities, improving the purity of the castings. Low coefficient of thermal expansion: Resistant to cracking during drastic temperature changes and has a long service life.Products UsageSelection of pore size: When using a filter, the pore size of the filter (number of pores per inch of product, PPI) must be determined based on the casting material, casting size, pouring temperature, and the number of inclusions in the molten metal; The pore diameters are mainly: coarse pores (10PPI, 15PPI), intermediate pores (20PPI), and fine pores (25PPI, 30PPI). Ductile iron parts generally use 10 PPl or 15 PP products, gray iron and copper castings generally use 15 PPI or 20 PPI products, and aluminum alloy castings generally use 20 PPI or 30 PPI products.Size selection: The greater the thickness of the foam ceramic filter, the better the strength of the filter and the higher the filtration efficiency of the filter, but the higher the cost of use. Considering the most suitable strength and filtration efficiency, the general recommendations are as follows: Size: 40MM~75MM, Thickness: 15MM~22MM Size: 75MM-120MM, Thickness: 22MM~25MM Size: 120MM~150MM, Thickness: 25MM~30MM Size: > 150MM, thickness 30MM~40MMFiltration capacity: The filtration capacity per unit area of the filter generally does not exceed: gray cast iron 1.5-2kg/cm2, ductile iron 1-1.5kg/cm2 (due to differences in casting system processes, try to design with the lower limit value to increase the insurance factor) .Filter area: The cross-sectional area of the sprue where the filter is placed should be appropriately expanded. Generally, the cross-sectional area of the normal sprue is 2 to 4 times.Placement location: The foam ceramic filter can be placed in various parts of the pouring system. It should be selected according to the characteristics of the parts and production conditions, and should be as close as possible to the casting to achieve the best filtration effect. In practical applications, according to different castings and requirements.ApplicationsCasting industry: Widely used in the filtration of cast iron, non-ferrous metals, high-temperature alloys and stainless steel castings, it can significantly reduce the scrap rate and improve the mechanical properties of products. Metallurgical industry: Used for the purification treatment of molten metals. In the field of chemical engineering: It is used as a catalyst carrier or for filtering high-temperature gases and liquids.Physical and Chemical IndexMaterialAlumina/ALOSilicon carbide/SICZirconia/ZrOColorWhiteGrayYellowPore Density8-60ppi8-60ppi8-60ppPorosity80-90%80-90%80-90%Refractoriness≤1100oC≤1500oC≤1700oCFlexure Strength>0.6Mpa>0.8Mpa>1.0MpaCompressive Strength>1Mpa>1Mpa>1.5MpaDensity0.3-0.48g/cm30.35-0.5g/cm30.9-1.5g/cm3Resistance to Heat Shocks6times/1100oC6times/1500oC6times/1700oCApplicationAluminum alloys And Others Nonferrous Metal Alloys.Nodular Cast IronMalleable Cast IronGray And Other Cast IronMetal Alloys with High Melting Points, Such As SteelAlloy SteelStainless SteelDrawings & DimensionsAvailable in various shapes (square, round, etc.) and different pore sizes (PPI - Pores Per Inch), typically ranging from 10 PPI to 60 PPI, to meet diverse flow rate and filtration precision requirements.Please contact us for more information.Company ProfileQingdao TTWY International Trade Co., Ltd https://ttwymachinery.en.made-in-china.com/Our company specialized in producing casting equipment.
