Alunima Foam Filter,Aluminum Factory Filters,Aluminum Industrial Filters,Foam Ceramic Filters,Microporous Ceramic Filters.
Alunima Foam Filter is made of non-stick aluminum material.
It has the characteristics of non-stick aluminum.
The product is white or milky white.
Alunima Foam Filter is suitable for the production of high quality and high requirements aluminum and aluminum alloy purification process through physical adsorption and Chemical action, which can effectively remove various oxidation inclusions generated during aluminum smelting process.
Thereby reducing casting defects, improving casting quality, and providing high-quality materials for further deep processing.
Alunima Foam Filter should be preheated before use.
The Aluminium filter plate is completely sealed in the aluminum water filter box to ensure that all the aluminum water passes through the filter plate, and the total amount of filtration must not exceed the specified limit.
If the amount of slag in the aluminum water is too high, multiple pieces of filtration or reduction should be adopted. The amount is adjusted.
The results of performance characterization show that the foam with modifier added has a through-hole ratio of over 90% and a compressive strength of up to 2MPa.
Considering the shape stability factor of the material, about 8% is added to the basic component. Bentonite can optimize the modification effect of the aluminum plant filter.
Alunima Foam Filter compressive strength
In the process of transportation and use of the Porous Ceramic Filter Plate, the filter plate must withstand the impact of a certain pressure from the outside.
So the index of compressive strength is also introduced in the standard as one of the basis for measuring the quality of the filter plate. The higher the compressive strength, the more durable the product, the better the quality, and vice versa.
In this standard, the index of compressive strength is determined to be 0.5 MPa or more.
Aluminum plant filter is made of high-quality high-purity Alunima, which is made of unique formula and advanced environmental protection technology. The three-dimensional network structure is uniform, with high strength, stable texture, no slag, high temperature resistance and strong thermal shock resistance.
Excellent performance, suitable for purification and filtration of high temperature aluminum and aluminum alloy solution, can filter non-metallic slag and slag as small as micron, make the surface of casting more smooth, reduce machining loss, filter can make aluminum liquid more evenly Filled with the cavity, the molten metal has a higher turbulence tendency during casting, and is finally converted into a very stable laminar flow through the turbulent flow of the three-dimensional pore structure, and the laminar flow has better filling of the cavity, thereby reducing the metal solution pair. Impact corrosion of the casting cavity, and significantly reduce the scrap rate, reduce production costs, and increase labor productivity.
Alunima Foam Filter Use Process
1. Clean the filter box.
2. Gently put the filter plate into the filter box and press the sealing gasket around the filter plate by hand to prevent the aluminum liquid from flowing.
3. Evenly preheat the filter box and filter plate to bring it close to the temperature of the aluminum liquid. Preheat to remove moisture and facilitate initial transient filtration. Preheating can be carried out using electrical or gas heating. Under normal circumstances, it takes about 15-30 minutes.
4. Pay attention to the change of the aluminum hydraulic head during casting. The normal starting head is 100-150 mm. When the aluminum liquid begins to pass, the pressure head will drop below 75-100 mm, and then the pressure head will slowly increase.
5. During the normal filtration process, avoid knocking and vibrating the filter plate. At the same time, the launder should be filled with aluminum water to avoid too much disturbance of the aluminum water.
6. After the filtration is finished, remove the filter plate in time and clean the filter box.
