1. In the smelting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, easy to oxidize, easy to react with water vapor and absorb hydrogen, easy to form various forms of non-metallic slag (such as furnace lining debris, chloride, carbide in flux, etc.) and coarse metal intercompound particles and so on.
2. Non-aluminum impurities are carried in during the process circulation by some of waste materials maked up the charging material.
Because the waste is coming from the process waste and scrap during each process in factory and the waste outside the factory, so, the composition is complex due to different way as well as the quality is poor. These impurities often make the billet produce bubbles and inclusions, which seriously affect the purity of the metal melt, thus further affect the processing properties, mechanical properties, corrosion resistance and the appearance quality of the product.
There are two kinds of materials to filter aluminum liquid, one is alumina ceramic foam filter, and the other is fiberglass filter mesh.

| Comparison items | Alumina ceramic foam filter | Carbonized fiberglass filter mesh |
| Main material | High-purity alumina ceramic | E-Glass fiberglass yarn |
| Technology | Three-dimensional foam porous structure | High-temperature carbonization treatment |
| Application | Aluminum liquid, high-end aluminum alloy, precision non-ferrous metals | Aluminum/aluminum alloy liquid, some copper alloys |
| Work temperature | Up to 1250℃, with better heat resistance stability | Up to 900℃ |
| Material features | Hard and brittle, not suitable for cutting, prone to being knocked and breaking | Soft and flexible, it can be cut into any shape as desired. |
| Filter Precision | Deep precision filtration, capable of removing fine impurities and fine debris | Coarse filtration, intercepting large slag and scum |
| Flowing effect | Uniform flow rate, strong and stable flow, eliminating turbulent flow, reducing slag pores | Liquid inflow rate is fast and flow stability effect is average. |
| Anti-erosion performance | Extremely strong. The pouring process remains free from deformation, detachment or slagging. | Generally, prolonged exposure to water can cause the threads to come off and the fabric to deteriorate. |
| Gas Emit | Almost no air leakage, and the casting has very few air holes. | Low exhalation volume |
| Install and use | It needs to be preheated to prevent cracking, the size is fixed, and it needs to match the gate. | Simple placement, no need for preheating, compatible with any gate. |
| Cast part quality | Aviation, automobiles, precision casting, high-end flaw detection aluminum parts | Applicable to ordinary aluminum castings |
| Cost price | The price is relatively high, and filtration cost is even higher. | Low price, high value for money |
| Core advantage | The filtration effect is the best, the purity of the molten steel is high, and the yield rate of qualified products is high. | Cheap, convenient to use, scalable, highly versatile |
| Core defect | Expensive, fragile and cannot be cut. | The filtration is not precise, and there is a risk of losing fibers. |
