Aluminium Ceramic Foam Filter Purchasing

Aluminium Ceramic Foam Filter Purchasing from Adtech, the filter can effectively remove various inclusions of aluminum melt, greatly improve the cleanliness of the metal, thereby improving product quality, reducing cost, and productivity has been improved to varying degrees.
The operation is easy, the process is easy to control, and there is no need for excessive investment, which is worthy of promotion and application.
The process and equipment for foam ceramic filtration and purification of aluminum liquid are applicable to all aluminum production departments, including book plates, strips, foils, bars, pipes, wires, extruded materials, forgings, primary aluminum ingots, reclaimed ingots and continuous casting. Production of rolling stock, etc.

Advantages of Aluminium Ceramic Foam Filter Purchasing from Adtech
It is estimated that regardless of the great benefits brought by the use of foam ceramic filter plates to purify the aluminum liquid and the foils and their products (such as cans, sequins for cars, PS printing plates, etc.), manufacturers of aluminum alloy profiles In terms of it, there are several obvious advantages:
1. Increase extrusion productivity
When using the filter plate to purify the 6063 alloy extrusion blank, we tracked a specific mold and found that the extrusion speed increased by about 20% and the productivity increased by nearly 15%.
2. Extend mold life and reduce the number of mold repairs.
3. Reduce the pressing force
When the filter plate was used to purify the 6063 alloy melt, it was found that the extrusion force was more than 3% lower than the unfiltered.
4. Significantly improved the surface quality of the aluminum profile.
From the above. The use of a foamed ceramic filter plate to purify the aluminum melt has tremendous advantages in terms of reducing production costs and improving product quality.
The ceramic filter plate is used to purify the aluminum liquid, and the device is an ordinary steel shell lined with a prefabricated refractory brick mat.
It is horizontally formulated in the metal flow cell, ie between the flow port and the casting well.
There is therefore no need to make major changes to the existing casting system, but only a small space.
Moreover, a filter plate can effectively filter all the metal of one melting, and it is very convenient to take out or replace after the end of use. It is also suitable for horizontal or vertical casting systems.

Aluminium Ceramic Foam Filter Purchasing from Adtech installation and function
The filtration efficiency of the ceramic foam filter is closely related to its proper installation and use.
At the same time, it is not possible to ignore the conventional and necessary measures taken to reduce the occurrence of inclusions in the process operations such as smelting, furnace treatment, and casting, because the filtration process is employed.
It is also necessary to prevent re-contamination of the cleaned aluminum liquid after filtration.
Its installation and use, in general, need to pay attention to the following aspects:
1. Use the filter plate correctly:
The size of the filter plate and the number of holes must be selected in consideration of the flow rate range of the specific casting type, the maximum liquid level of the metal during filtration, the total filtration amount, and the cleanliness of the original aluminum liquid.
2. Pre-melt filtration treatment can not be ignored:
Such as molten aluminum furnace and holding furnace normal slag, cleaning furnace; furnace refining. In particular, an in-line degassing device is still necessary because it not only reduces the hydrogen content of the melt, but also removes some of the non-metallic inclusions.
3. The filter plate must be compatible with the square refractory block:
The two are adapted to seal, so as to prevent the metal from flowing into the casting box from the gap without being filtered, and also avoid the failure of the foam filter plate to float in the aluminum water due to the excessive light weight.
4. Preheat before use:
Preheat to remove moisture and facilitate initial transient filtration. Preheating can be carried out using electrical or gas heating. Under normal circumstances, it takes about 15 minutes.
5. During normal filtration, no slag is required to avoid knocking and vibrating the filter plate. At the same time, the launder should be filled with aluminum water to avoid too much worries of aluminum water.
6. After casting, drain the metal in the flow cell and filter plate. There is a vibrator abroad that is placed on the filter plate and shaken for one minute to shake off about 75% of the remaining liquid metal from the filter plate.
7. Finally clean the perimeter and remove the filter plate after solidification.
