10 12月 Molten Aluminum Filter Medium
Molten Aluminum Filter Medium has countless micropores uniformly distributed in the network state, and the pore size is slender and curved, and has good penetration. It has the characteristics of capillary, so that the solid particles form an arch bridge at the micropore diameter, which has little effect on the filtration rate. Will not clog micropores.
During filtration, the aluminum melt is blocked by the filter plate and flows along the tortuous channels and pores in the filter plate.
The impurities and inclusions in the aluminum melt are in contact with the inner surface of the filter plate pores under the effects of deposition, inertia, interception, etc., and stay in the gaps, shrinkage holes, caves and other places in the filter plate, and are affected by the axial direction of the melt fluid. Pressure, friction, surface adsorption, etc.
The impurities and inclusions in the molten aluminum are firmly left in the filter plate and separated from the molten aluminum.
In large enterprises, aluminum is filtered from several tons to hundreds of tons of liquid aluminum during continuous or semi-continuous processing. This requires a large-area filter, which is installed in the system to transfer the melt from the melting or transfer furnace to the casting equipment.
Molten Aluminum Filter Medium specifications are 7 * 7in, 9 * 9in, 12 * 12in, 15 * 15in, 17 * 17in, 20 * 20in, 23 * 23in, 25 * 25in, 26 * 26in or customized according to the shape and size of customer needs.
The mesh number is 25, 30, 35, 40, 45, 50, 55, 60, 70, 80, 90 ppi.
The service life of a single ceramic filter plate depends on the size of the filter plate, the number of holes and the cleanliness of the metal. For a single filter plate, the size and number of holes are fixed.
In order to improve the filtration effect, some manufacturers consider two-stage filtration, which is generally used in combination with the front coarse and the fine. The filtration effect is good. For impurities and inclusion particles of about 20-30u, the removal rate can reach 75%-90%. More flexible.
The cleaning of the filter box and the replacement of the filter plate are simple, convenient and fast, and it is very flexible in the production of various alloys.
