Product Overview

Description



Company Information


ü  Name


 


Ceramic foam filter


 


ü  Application


 


It is widely applied to filter the  aluminum and aluminum alloys. Through physical adsorption and chemical action, it can effectively remove all kinds of oxidation inclusions in the process of aluminum smelting, thus reducing casting defects, improving casting quality and preparing high quality materials for further processing.

ü  Instructions


 


The filter plate shall be preheated before use, and shall be completely sealed in the filter box to ensure that all aluminum water passes through the filter plate, and the total amount of filtration shall not exceed the limit. If the amount of slag in aluminum water is too much, multiple filtration or reduction of the amount of filtration shall be adopted.


 


 


ü  Features


 


1. Effectively remove all kinds of inclusions with fineness up to micron in aluminum water, and make aluminum water become smooth laminar flow, which is conducive to mold filling;


2. It has good mechanical strength, chemical stability, good abrasive resistance and thermal shock resistance.


3. The strictly controlled hole size and filtration rate can obtain excellent filtering effect;


4. There is an aluminum silicate liner around the filter plate, which can help seal and ensure no metal liquid bypass.


 


ü  Benefits


 1.Increase extrusion productivity


2.Extend the life of the mold, and reduce the number of mold repair.


3.Reduce extrusion pressure


4.Significantly improve the surface quality of aluminum profiles.


ü  Attentions and tips


 


1.Right way to choose  filter plate:


The size of the filter plate and the number of holes must take into account the flow rate range of the specific casting type, the maximum liquid level of the metal during the filtration, the total filtration amount, the cleanliness of the original aluminum liquid and other factors.


2.Melt filtration pretreatment should be paid attention:


Such as melting aluminum furnace and heat preservation furnace normal slag scraping, cleaning furnace; Furnace refining, etc. In particular, in-line degassing is still necessary because it not only reduces the hydrogen content of the melt, but also removes some non-metallic inclusions.


3.The filter plate shall be compatible with the square refractory filter box:


The two are suitable for sealing, which can not only prevent the metal from flowing into the casting box from the gap without filtering, but also avoid the failure because the foam filter plate is too light and floats in the aluminum water.


4.Preheat before use:


Preheat to remove moisture and facilitate initial instantaneous filtration.Preheating may be done by electric or gas heating.Normally, it takes about 15 minutes.


5.In the normal filtration process, there is no need to beat slag and avoid knocking and vibration of the filter plate.


Meanwhile, the flow trough should be filled with aluminum-water to avoid too large disturbance of aluminum-water.


6.After casting, drain the main channel and the metal on the filter plate.


7.Finally, clean the surrounding areas and take out the filter plate after solidification.


8.Storage:keep products in ventilated and dry place to avoid  getting damp; no things on them.
