It has many advantages such as stable chemical properties, high strength, high temperature resistance, good thermal shock resistance and large specific surface area. The organic foam impregnation method is the most common process for preparing porous ceramics at present, because it can prepare a porous ceramic with uniform pore distribution, high porosity, and a three-dimensional network structure. Porous Ceramic Filter Plate uses a foam impregnation process to prepare high porosity, high strength alumina porous ceramics. Scanning electron microscopy (SEM) results show that the pretreatment method of the foam and the firing temperature have an effect on the performance of the porous ceramic. Polyurethane foam is used as the forming skeleton, and the pretreatment process of alcohol soaking and water washing is carried out. The finally prepared alumina porous ceramic has a high porosity, uniform pore distribution, good pore connectivity, and a pore diameter of 0.3 to 1 mm. The optimum firing temperature of the ceramic is 1600 ° C, at which time the ceramic porosity is maintained above 67% and the flexural strength is 5.6 MPa.

porous ceramic filter is authorized by www.adtechamm.com to sell alumina foam ceramic filters to local aluminum smelters and foundries in Iran. The alumina porous ceramic filter is installed on the CFF BOX machine to filter the liquid impurities of the aluminum alloy to cope with the high added value and high technical performance of the aluminum alloy in the precision casting production of transportation and transportation. Casting Filter Agent must understand that the quality of aluminum melt is very important, it strongly affects the performance of the next processing and the quality of the final product. Therefore, all countries in the world have a great desire for the refining of aluminum melt. There are many reasons for aluminum pollution. On the one hand, during the melting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi-molten state, which is easily oxidized, easily reacts with water vapor to absorb hydrogen, and easily forms various non-forms. -Metal slag (such as coated parts, chlorides, and carbides in flux, etc.) and large intermetallic particles. On the other hand, some waste products that constitute the charge will introduce some non-aluminum impurities during the recycling process. Because the waste comes from process waste, geometric waste, and off-site waste from various factory processes, the route is different, the composition is complicated, and the quality is not high. These impurities often generate bubbles and inclusions in the slab, which seriously affect the purity of the molten metal, and further affect the processing performance, mechanical properties, corrosion resistance, and product appearance quality. Nowadays, there are many ways to remove these harmful substances and purify molten aluminum. The different methods, these methods can be divided into two categories: in-furnace purification and continuous out-of-furnace treatment (that is, online treatment). According to different functions, it can be divided into main degassing or slag removal. porous ceramic filter (www.adtechamm.com) introduced the use of porous ceramic filter plates to continuously filter molten aluminum. External continuous treatment, the main purification operation is slag removal. The ceramic filter for casting has a certain strength mesh structure, which can withstand the pressure difference of the metal liquid surface and the impact of the metal flow, but it is fragile and fragile. Because this material has a precise structure, uniform quality, wide surface, and excellent filtering effect.

Porous ceramic filteris used to filter and purify non-metallic impurities in molten aluminum, which is very important to ensure the quality of aluminum products. Molten metal usually contains impurities in the form of inclusions, which are not removed during the refining process. In order to obtain advanced metal raw materials for thin plate manufacturing, fine wire drawing and precision casting, it is usually necessary to pass molten metal through a filter to remove these inclusions. In particular, molten aluminum often contains entrained solids, which are harmful to the final cast metal product. These entrained solids appear as inclusions in the final cast product after the molten metal is solidified, and cause the ductility of the final product to decrease or the smoothness and anodizing properties of the final product are poor. Inclusions may come from several sources. For example, inclusions may come from a surface oxide film that is broken and entrained in the resulting molten metal. In addition, inclusions may come from insoluble impurities, such as carbides, borides, etc. or corroded furnace and trough refractories. Provide reticulated organic polymer foam. Impregnate the foam with the aqueous slurry. Dry and heat the impregnated polymer foam to remove its organic components. It is fired at a high temperature to produce the ceramic foam filter. Porous ceramic filter uses elastic sealing devices or gasket-type seals to seal the filter plate in place. The seal surrounds the filter plate at the beveled corner of the filter plate. The gasket seal ensures that there is no leakage in the installation and provides an effective separation medium, which is essential for easy disassembly. In addition, since gaskets or sealing devices prevent metal from entering the sealing surface of the holder unit, their use greatly simplifies cleaning and effectively extends the life of the unit by eliminating the problem of metal corrosion. In addition, due to its elasticity, the gasket can provide sufficient friction to fix the filter body in the proper position in the bracket or filter. No need to use other types of compression devices. The elastic sealing device should not wet the specific molten metal, resist its chemical corrosion, and should be fire-resistant enough to withstand higher operating temperatures.

porous ceramic filter explains the mechanism and usage suggestions of foam ceramics for casting Filtration mechanism of porous ceramic filter The porous ceramic filter separates the inclusions in the liquid casting alloy through three physical and chemical effects on the molten metal, so as to achieve the effect of purifying the molten metal. Filter cake effect The complex foam ceramic structure can effectively block slag mechanically. When the molten metal passes through the porous ceramic filter with complex structure, the filter medium filters out the inclusions larger than the pore size of the filter surface through mechanical separation, and makes them precipitate on the inflow end of the filter liquid metal. As the number of inclusions on the surface of the filter increases, a layer of “filter cake” will gradually form, which will further narrow the flow channel of the molten metal. Therefore, the surface of the new filter medium can filter out finer inclusions. The inside of the medium also has a filtering effect. Among the many small holes that penetrate the ceramic body, some show tiny slits, and some have dead corners. These different areas of change are possible positions for intercepting inclusions, and there are also “filters” inside the filter. “Pie” effect. Surface effect When the molten metal flows through the ceramic body with a complex structure, it is divided into many small streams, which increases the contact area and contact probability of the inclusions in the molten metal and the filter medium. Because the surface of the filter is extremely small concave and convex, the size of the concave block is about 1~10um, which has electrostatic adsorption and adhesion interception effects on inclusions. Rectification effect When the molten metal flows through the porous ceramic filter it is divided into many small unit streams, the diameter of which is small, so that the Reynolds number becomes smaller, and the liquid flow tends to be laminar. When the molten metal is in a laminar flow state, because the density of the molten metal is much greater than the density of the inclusions, the inclusions have sufficient time to float up and remove, that is, the foam ceramic filter can assist the runner to stop the slag. After the filter is placed in the gating system, the resistance to the flow of the molten metal increases. The molten metal flowing in the runner is easy to form a full motion, and the flow rate is reduced, which is conducive to the floating of inclusions and staying on the top surface of the runner. Recommendations for the use of porous ceramic filter 1. According to the melting point of the alloy, select the filter of the appropriate material to avoid excessive temperature, damage the function of the filter and fail to achieve the filtering effect. 2. Select the corresponding mesh, and the purification effect should match the casting requirements. 3. Try to use the upper limit of the casting temperature to increase the fluidity of the metal. 4. When the filter is placed horizontally under the mouth cup or parting surface, the casting height should not exceed 20cm. It is best to flush the metal liquid on the mouth cup wall, not directly to the filter. 5. The filter must be handled gently. When not in use, place it in a dry and ventilated place to avoid moisture absorption affecting the strength of the filter.

The porous ceramic filter is an inorganic material, and the main crystalline phase is xonotlite, which has stable physical and chemical properties, and the product does not adhere to aluminum water. Product use: AdTech a luminum water slag blocking device is used together with casting mold. By setting the slag ring, the filtered aluminum liquid first enters the annular range formed by the slag ring body, and slag such as oxidation slag may be brought in. In the crystallizer, the slag blocking device body can intercept the slag such as oxidized slag, and prevent it from flowing into the inner side of the slag blocking device, and control the scum such as oxidized slag to be outside the slag blocking device, thereby reducing the aluminum alloy ingot. Risk of contamination by slag. The advancement of alumina and DC electrolysis technology in the aluminum industry production laid the foundation for the industrial scale development of aluminum production. By the end of the 19th century, the production cost of aluminum began to decline significantly, and aluminum itself has become a common common metal. In the early 20th century, in addition to daily necessities, aluminum was mainly used in the transportation industry. In 1901, aluminum panels were used to make automobile bodies. In 1903, Alcoa supplied aluminum parts to Wright Brothers. Aircraft. Automobile engines began to use aluminum alloy castings, and the shipbuilding industry also began to use aluminum alloy thick plates, profiles and castings. With the increase in aluminum production and advances in science and technology, aluminum is used in other industrial sectors (such as medical equipment, aluminum printing plates and refining). The use of deoxidizers for steel, packaging containers, etc. is also becoming more widespread, greatly stimulating the development of the aluminum industry. In 1910, the world’s aluminum production increased to more than 45,000 tons. Large-scale production of aluminum foil and other new products, such as aluminum hoses, aluminum furniture, aluminum doors and windows and curtain walls, and various new products such as aluminum cookware and household aluminum foils have also been successively produced. The emergence of aluminum has made a big step forward in the popularity of aluminum. In 1906, Wilm, Germany invented a hard aluminum alloy that doubled the strength of aluminum and was used extensively in aircraft manufacturing and other arms industries during the First World War. Since then, aluminum alloys with different compositions and heat treatment conditions have been developed. These alloys have different characteristics and functions, which greatly expand the use of aluminum and enable the rapid application of aluminum in industrial sectors such as construction, automotive, railway, shipbuilding and aircraft manufacturing. development of. With the development of the aluminum industry, more and more corresponding filter slag products are on the market, and these products require more challenges for the porous ceramic filter

porous ceramic filter have excellent strength and high temperature impact resistance and chemical corrosion. It can withstand high temperatures up to about 1560 °C. They are therefore suitable for the casting of all copper alloys and cast iron. The ceramic foam filter can significantly improve the quality of cast iron parts and reduce the scrap rate. It can also be used in the continuous casting and rolling process, and can be manufactured to all standard sizes and different thicknesses. The basic materials of theporous ceramic filterare three kinds of silicon carbide, zirconium oxide and aluminum oxide. The foam ceramic filter has excellent filtering effect on copper water or aluminum water, and utilizes a three-dimensional structure to effectively remove oxide inclusions and other non-metallic inclusions by blocking capture adsorption. Whether it is gray iron, ductile iron or shaft body, cylinder or complex large parts, precision metal parts are filtered, the product quality will get satisfactory results. porous ceramic filter Application The foam ceramic filter is also suitable for copper alloys such as copper, bronze, brass, etc., to reduce the turbulence of the copper liquid and to rectify and purify the molten copper liquid. Particularly valuable is that the copper castings that have been purified by filtration have a significant life extension in high-demand or harsh environments such as turbines and chemical parts of marine vessels, and have good effects on cast copper parts with surface polishing requirements. 3. Foam ceramic filters also play an important role in the traditional copper industry and electric and electronic copper industry and continuous casting and rolling processes. Since copper and alloys, including zinc alloys, have a greater specific gravity and produce greater thermal shock during casting, the use of silicon carbide foam ceramic filters in the copper casting process is generally strictly sized. porous ceramic filter Material The basic material of the zirconia foam ceramic filter is zirconia ZrO2. The zirconia filter has a heat resistance temperature higher than about 1760 ° C and has a very high strength and an excellent high temperature impact force. Cast steel parts are widely used in applications that require high strength and elongation requirements. Therefore, steel castings are very sensitive to defects caused by impurities. The excellent characteristics of the zirconia foam ceramic filter can effectively remove the impurities that ultimately lead to product quality defects. The impurities are mainly composed of non-metal particles, slag, and refractory fragments, which improve the surface quality and mechanical properties of the casting and reduce the scrap rate. The zirconia foam ceramic filter can make the molten steel more evenly fill the cavity, and the molten metal has a higher turbulent tendency during casting. The turbulent flow of the three-dimensional pore structure of the zirconia foam ceramic filter is finally converted into a very stable layer. flow. The laminar flow fills the cavity better, which reduces the impact corrosion of the metal solution on the casting cavity and significantly reduces the reject rate. 
How to use the porous ceramic filter0adtech122022-06-27 20:51:02
First of all, the primary classification of scrap aluminum is carried out and stacked in grades, such as pure aluminum, wrought aluminum alloy, porous ceramic filter, and mixed materials. For waste aluminum products, it should be disassembled to remove the steel and other non-ferrous metal parts connected to the aluminum material, and then wash, crush, magnetic separation, dried, and other processes to make waste aluminum. The liquefaction and separation of scrap aluminum is the development direction of recycling aluminum metal in the future. It combines the pretreatment of scrap aluminum and re-casting, which not only shortens the process flow, but also avoids air pollution to the greatest extent, and greatly improves the recovery rate of the net metal. The device has a porous ceramic filter that allows gas particles to pass through. In the liquefied layer, aluminum precipitates at the bottom, and organic matter such as paint attached to the waste aluminum is decomposed into gas, tar, and solid charcoal at 450 ℃ or more. Then complete combustion through the oxidation device inside the separator. The waste is stirred by a rotating drum, mixed with the dissolved liquid in the bin, and impurities such as sand and gravel are separated into the sand and gravel separation zone, and the dissolved water carried out by the waste is returned to the liquefaction bin through the recovery propeller. According to the preparation and quality status of scrap aluminum materials, and in accordance with the technical requirements of recycled products, select and match and calculate the number of various materials. Ingredients should consider the degree of metal oxidation burning loss. The oxidation burning loss of silicon and magnesium is larger than that of other alloying elements. The burning loss rate of various alloying elements should be determined in advance through experiments. The physical specifications and surface cleanliness of scrap aluminum will directly affect the quality of recycled products and the actual metal recovery rate. For waste aluminum that is not clean from oil removal, up to 20% of the effective ingredients will enter the slag. Recycled wrought aluminum alloys. Wrought aluminum alloys that can be produced from scrap aluminum alloys include 3003, 3105, 3004, 3005, 5050, etc., of which 3105 alloy is mainly produced. In order to ensure that the chemical composition of the alloy material meets the technical requirements and pressure processing process requirements, a part of primary aluminum ingots should be added when necessary. Only a small part of recycled cast aluminum alloy scrap aluminum is recycled into the deformed aluminum alloy, and about 1/4 is regenerated into deoxidizer for steelmaking, most of which are used for recycled cast aluminum alloy. Only a small part of scrap aluminum is recycled into the wrought aluminum alloy. The die-cast aluminum alloy A380, ADC10, etc., which are widely used in the United States, Japan, and other countries, are basically recycled from scrap aluminum. The main equipment for secondary aluminum generally uses a dedicated static furnace with oil or gas. Dubai Aluminium recommends Alu porous ceramic filter manufacturer Adtech to UAE Aluminium Company.

What is the filtering principle of Foam Furnace Filters? By the gap? wrong! The porous ceramic filter is a new type of filter plate made of an industrial sponge as a carrier, filled with heat-resistant ceramics, and then sintered. When the porous ceramic filter filters the aluminum liquid, the aluminum liquid flows through the tortuous holes of the ceramic Foam Furnace Filter, and the non-metallic impurities and oxide film (commonly known as slag) in the aluminum liquid are affected by the axial pressure, friction, and surface adsorption of the aluminum liquid. The combined effect of the slag is retained on the inner surface of the hole and the crevice of the ceramic filter plate, thereby separating the slag and the molten aluminum. After a period of filtering, the slag remaining on the porous ceramic filter also participates in the adsorption of the slag, which can play a filtering role. Since the performance of the slag adsorbed on the porous ceramic filter and the slag to be adsorbed in the aluminum liquid are exactly the same, the surface area ratio is much larger than that of the ceramic filter plate, and the surface activity is much greater than that of the ceramic filter plate, so the ability to adsorb and trap the slag in the aluminum liquid is far Much larger than the ceramic filter plate. Because of this, the porous ceramic filter can filter out the fine slag that is many times smaller than its own hole. During the filtration process, the slag adsorbed on the Foam Furnace Filters gradually grows up after adsorbing and trapping the slag in the molten aluminum. Under the agitation and scouring of the liquid flow, the extremely low-strength slag may break or fall off the porous ceramic filter. In the process of slag falling off, if the porous ceramic filter is thicker or has small holes, it may be intercepted or adsorbed again.
