The ceramic filter for aluminum is surrounded by a gasket, which can prevent the molten aluminum from leaking through the interface. AdTech ceramic foam filter uses three different types of gaskets, namely fiber paper material, fiber cotton material, and expanded cotton material. It can effectively remove various impurities in the aluminum melt, greatly improve the cleanliness of the metal, thereby improving product quality, reducing costs, and improving productivity to varying degrees.
The ceramic foam filter molten metal filtration is applicable to all-aluminum production departments, including aluminum plates, strips, foils, rods, tubes, wires, extrusion materials, forgings, original aluminum ingots, recycled ingots, and continuous casting.
It is estimated that regardless of the huge benefits brought by the use of ceramic foam filter to purify molten aluminum and aluminum foil and their products (such as cans, car sequins, PS printing plates, etc.), aluminum alloy manufacturers have several obvious advantages as far as it is concerned. :
- Improve extrusion efficiency: When using the filter plate to purify the 6063 alloy extruded billet, we tracked a specific die and found that the extrusion speed increased by about 20% and the productivity increased by nearly 15%.
- Extend mold life and reduce mold maintenance times.
- Reduce stress: When the 6063 alloy melt was purified using a filter plate, it was found that the extrusion force was lower than the unfiltered extrusion force by more than 3%.
- Greatly improve the surface quality of aluminum profiles.
In terms of reducing production costs and improving product quality, the use of ceramic foam filters to purify aluminum melt has great advantages. The ceramic filter is used for purifying molten aluminum. The equipment is an ordinary steel shell lined with prefabricated refractory brick pads. It is prepared horizontally in the metal flow cell, that is, between the orifice and the casting well.
Therefore, there is no need to make major changes to the existing casting system, but only a small space. Moreover, the filter plate can effectively filter a molten metal, and it is very convenient to remove or replace after use. It is also suitable for horizontal or vertical casting systems.
