Ceramic Foam Filter Denmark is currently the most effective tool for removing oxidized inclusions in aluminum melts.
Aluminum alloy melt purification technology is the most effective method to improve the quality of cast rods, and is also the common goal of aluminum industry casting.
Use and selection of Ceramic Foam Filter Denmark The foam ceramic filter plate is installed in the filter box between the furnace port and the distribution plate.
The filter box can withstand many times of chilling and shock without cracking, and has the advantages of high strength and good thermal insulation performance. It is currently the best material for making filter boxes and flow channels.
The closer the filter box is to the diverter plate, the better, because it can shorten the flow distance of the aluminum liquid after filtration and reduce or avoid the re-generation of oxides.
The aluminum liquid flows out from the furnace mouth through the filter box, and then flows into the distribution plate through the flow groove.
When the filter device is started, the drop before and after the melt filtration is about 50mm, but with the extension of the filtration time, the inclusions on the surface of the filter plate and the hole wall increase, the filtration flow rate decreases, and the drop before and after the increase increases, to the end of casting, the drop increases To 60-120mm.
Therefore, the selection of Ceramic Foam Filter Denmark must be based on the flow of aluminum liquid
Secondly, the cleanliness of the melt, the maximum content of inclusions and the total throughput of the melt should be considered.
When designing the filter device, it is necessary to ensure that the filter plate is immersed in the aluminum liquid when the melt is cast, according to the specifications of the selected filter plate, and considering the drop of the furnace mouth and the distribution plate.
In addition, it must be considered that the installation and disassembly are very safe and convenient. After the melt casting is completed, the aluminum liquid in the filter box can be completely discharged.
The practice of the filter plate surface has proved that the foam ceramic filter plate is currently the most effective tool for removing oxidized inclusions in the melt.
The general fiber filtration can only remove large inclusions, and the foam ceramic filter plate can filter out large inclusions and fine inclusions at the same time.
The main effect of the filter plate is to ensure its size and porosity. The larger the porosity of the filter plate, the worse the slag removal effect. For the strict aluminum castings, the filter plate with small porosity should be selected.
