User Manual:

1. Clean 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 flow of molten aluminum.

3. Evenly preheat the filter box and filter plate to make it close to the temperature of the molten aluminum. Preheat to remove moisture and facilitate initial instant filtration. Preheating can be carried out using electric 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 initial pressure head is 100-150mm. When the molten aluminum begins to pass, the pressure head will drop below 75--100mm, and then the pressure head will gradually increase.

5. During the normal filtration process, avoid knocking and vibrating the filter plate. At the same time, the launder should be filled with molten aluminum to avoid too much disturbance of the aluminum liquid.

6. After filtration, take out the filter plate in time and clean the filter box.

How to choose the suitable Alumina Ceramic Foam Filter Plate?

First of all, according to the impurity content of aluminum melt, melt transfer flow rate of the final casting product quality requirements. 

1. The plate with a large hole mesh can be chosed when a lot of impurities contained and normal quality of casting products required.

2. New type plate with small holes can be selected when the quality requirements of casting products are high.

Our alumina ceramic foam filter plates adopt the organic bubble body with three-dimensional network structure and connected pores as the carrier, which is penetrated into the thixotropic alumina slurry, and adopts the automatic extrusion process with four square correction center distance, so that the slurry is evenly coated on the carrier bubble skeleton, and is roasted at 1180℃ after drying and curing.

Installed in the filter box for aluminum alloy liquid impurities filtration, to meet the production of high value-added, high technical performance of aviation, transportation and other aluminum alloy precision casting. Such as: computer hard disk, printing with PS board base, can material, jet turbine engine fan blades and other products, to achieve the ideal cleanliness, to obtain good results.

3. The selection of the filter plate specifications is based on the flow rate and the total amount of melt through. The flow rate is large, the total passing amount is large, and the filter plate holes are small, so the larger specifications are selected.

Secondly, look at its color, shoot its body, burn its things during select the filter plate.

1. The color is pure and no impurity that means the material is uniform; The hand is not sticky that means the surface is not sprayed with binder, which will not cause secondary pollution.

2. Holding the filter plate with one hand and clapping with the other hand, if the ceramic particles continuously drop when beating the filter plate, it means that a poor quality filter plate, which will cause secondary pollution of liquid aluminum.

3. Use an open flame or electric heating to burn red and make it cooled at room temperature immediately without cracking slag, it is a good filter plate.

Thirdly, The effective specific surface area or porosity calculation of the foam should be carefully evaluated when selecting.

1. The mesh homogeneity of the surface layer of the filter plate can be observed, and then the mesh homogeneity of the cross section can be observed.

2. If possible, the porosity can be measured by drainage method.

3. The three-dimensional mesh is homogeneous, the porosity is relatively large, means it is an excellent foam ceramic filter plate.
