<\/p>\nFor the production of high-end products, deep bed filtration is recommended for process configuration: degassing device + deep bed filtration device + cast ceramic filter.<\/p>\n
Cast Ceramic Filter filtration is used before casting to avoid media loss due to deep bed filtration, which causes too many inclusions to accompany molten aluminum casting, resulting in a lot of waste.<\/p>\n
<\/p>\n
And according to the output and production plan, consider the corresponding deep bed preheating method (online or offline). The process configuration recommendations for the use of tubular filters: degassing device + tubular filters (at least two parallel), most of the aluminum processing enterprises in Japan use this arrangement.<\/p>\n
In order to achieve energy saving and emission reduction and form an \u201celectrolytic aluminum-aluminum processing\u201d industrial chain, some enterprises use electrolytic aluminum liquid as raw materials to produce steel ingots.<\/p>\n
Since the impurity composition of electrolytic aluminum is complex and there are many non-metallic slags, it is recommended to use a ceramic filter device before the tubular filter. The harm of metallurgical defects to aluminum processing deformation production and the mechanical properties of the final product cannot be ignored. Therefore, attention should be paid to the purification treatment of aluminum melt.<\/p>\n
Before the filter is used, the gas and slag content is too high, which will cause the ceramic foam filter to block. Therefore, adding a degassing device before filtering can make the purification process of liquid aluminum more smooth.<\/p>\n
After cleaning the Casthouse, apply a layer of BN refractory\u00a0to the inner surface of the CFF Casthouse, and then gently place the Casthouse Cff Filter on it.<\/p>\n
