Ceramic Foam Filter (Jintai)

Ceramic foam filter Ceramic foam filter is developed as a new type molten metal filter to decrease casting flaw in recent years, designed for filtering impurities from liquid metals. With the distributing pores net structure, they are able to increase the surface areas, absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less, and the cast quality becomes much better. Jintai ceramic foam filter: Material including al2o3, sic, zro2. Shape in square, round, cylinder. Pore size: 8~60ppi Special size is available upon request. Cartons on pallets

Ceramic foam filters Arffil ceramic foam filters are characterized as high permeation rate, good strength and thermal shock resistance, stable quality and without loosing impurity in high temperature either in big size or small ppi products. Advantages compared with traditional filtering materials: Thermal and chemical stability in high temperatureücavoiding the chemical reaction with the filtered molten metal. High porosity and good mechanical strength in elevate temperature due to its pure ceramic composite. Full open cell without loosing ceramic particles or powders (snowing) during filtrating. Low head loss, easy operation, energy save. Make metal flow reposeful and avoid the sputtering and backset, this increases the surface quality of the cast, prevent the pore disfigurement and finally lower down the waster rate. Box quantity depends on the filters's dimensions

Ceramic foam filter 1. Alumina work at 1100 centigrade degree, apply for aluminium foundry. 2. Zirconia work at 1700 centigrade degree, apply for steel, stainless steel foundry. 3. Silicon carbide work at 1500 centigrade degree, apply for iron, copper, copper alloy foundry. 4. Fused zriconia-alumina work at 1600 centigrade degree, apply for some steel which have lower tem. Requirement. Ceramic foam filter is been made by specific procedures and have peculiar bone-frame holes just like the shape of foam(called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. Compare to similar ones, our products have many advantages as below: Stable chemical composition Excellent strength Resistant to high temperature Calm down of the turbulent flow of metal nicely Big m2/m3 Superior dimensional tolerances: +0/-2.5 Suggestions: A. Control the melting point satisfactorily. Especially high temperature will destroy it's function. B. Suitable ppi for different casting materials. C. Use the maximum temperature as soon as possibly. D. The pouring highness don't exceed 20cm commonly, and metal liquid don't touch the filtration directly. Standard export packing

Silicon Carbide Ceramic Foam Filter Silicon Carbide Ceramic Foam Filter is mainly made of high purity fine silicon carbide powder, which is suitable for filtrating Ductile, Grey Iron, Vermicular Cast Iron and some Iron Alloy and also for filtrating non-ferrous alloy, such as Cooper alloy and Aluminum alloy. It can remove impurities efficiently, and make metal filling steady in mould. It can also reduce air flow and casting impact in mould, and decrease pin hole, sand hole defeats to increase casting quality and product rate. These series of products are newest products, which are produced through special material formula and latest advanced technology. Compared with normal ceramic foam filters, these new series products can be used at a higher temperature, which have higher strength at room temperature and high temperature. The physical property of this special material enables our filters to have a better thermal shock resistance. They are suitable for harsh casting condition, such as placing on the bottom of vertical runner and casting at high temperature.

Ceramic foam filter used for casting Our products have many advantages such as superior porosity, big m2/m3, high temperature resistance and excellent thermal shock resistance (see detail in technical data), it used in foundry, noise elimination and other industries widely. And especially for the foundry & casting industry. Mechanic deterring: remove big oxide Filtration: filtrate small impurities and oxide Commutated function: calm down turbulent f¦claminar flow Mixed round function: mix the distributaries and confluence flow equality, reduce air bubble Absorbing function: the myriad eyelets which only been found in microscope can absorb smaller impurities, make more excellent metal liquid 31*31*22(cm) wrapped every pieces with soft plastic materials then packed in carton

Cff-s is a range of new generation silicon carbide based ceramic foam filters with a consistent, high level performance in terms of metal flow rate and filtration efficiency. Cff-s filters are intended for filtering grey, ductile iron and nonferrous metals at the temperatures up to 1450 â°c. The filters can be placed in the gating system of the mould as well as in combination with exothermic extensions for direct casting/pouring on the filter. They can also be used for continuous non ferrous metal filtering, e.G. Production of copper wires, roads. Features: 1. High strength 2. Excellent corrosion resistance 3. Outstanding thermal shock resistance 4. Available in kinds of shapes, in a variety of pore sizes, e.G.10ppi, 20ppi, etc. Functions: 1. Clean iron castings 2. Fewer inclusions 3. Increased casting yield 4. Cost-savings from reduction in scrap 5. Lower costs for machining of the castings Standard dimensions and technical parameters Dimensions (mm) Pouring rate(kg/s) Filtration capacity(kg) Grey iron Ductile iron Grey iron Ductile iron 40x40x22 4 3 65 32 50x50x22 6 4 100 52 75x50x22 9 6 150 75 75x75x22 14 9 220 100 150x150x22 50 36 900 450 170x150x32 62 42 1020 510 200x170x32 84 56 1400 700 D50x22 5 4 80 40 D60x22 6 5 110 55 Above figures are only for reference .Other special specification could be customized.
