Aluminium 7075 Ceramic Filter For Foundry is the most effective method to remove inclusions in molten aluminum. The filtration principle is the same as the ceramic tube filtration. It is a deep filtering mechanism.
Ceramic Filter For Foundry has a large flow capacity and is suitable for filtration and purification in continuous casting and continuous rolling production.
The metal filters and fiber cloth filters used by low-end customers can only remove large inclusions in the aluminum alloy melt, but cannot remove the inclusions below micrometers. The metal filter will contaminate the aluminum alloy. Ceramic Filter For Foundry can filter out fine inclusions and significantly improve the mechanical properties and appearance quality of the product.
The non-metallic inclusions in the aluminum melt will produce surface cracks and pinholes during the aluminum foil rolling process. Surface intimacy is also a defect that is not allowed for high-end PS board bases.
In order to meet the needs of high-grade aluminum foil blanks and PS plates, it is necessary to remove non-metallic inclusions in the aluminum melt.
Filtration has become an important link in the production of aluminum foil. The purpose of filtration is to remove non-metallic inclusions in the aluminum melt as much as possible.
When using Aluminium 7075 Ceramic Filter For Foundry, if the melt is very dirty, the filter will quickly become clogged.
Using two filters can extend the life of the filter.
In terms of filtration efficiency, it is far more effective to increase the collection efficiency by increasing the filtration area than adding a coarse filter to it.
A more effective arrangement is to place two large-area fine filters in parallel at the outlet of the launder, instead of using one thick and one thin in series.
Choose filter materials of different thicknesses to change their ability to capture inclusions.
Use filter materials of different pore sizes to make a reasonable combination from large pores to small pores, that is, at the same time change the filtration parameters, increase the filtration thickness and the number of filtration stages to enhance the ability to capture inclusions.
Increase the flow cross-sectional area, reduce the flow rate of the melt, increase the probability of capturing inclusions, etc., to improve the filtering effect to achieve the desired purpose.
