Casthouse Cff filter out is used for casting aluminum ingots and aluminum rods. The Ceramic foam filters had been extensively used at domestic and abroad, saving production costs. on the way to acquire the satisfactory filtration treatment procedure, it is very important to configure the filter fairly.


lightly location the Casthouse Ceramic foam filter clear out into the Casthouse.

The CFF Casthouse ought to be thoroughly cleaned before the use of the molten aluminum filter out to prevent the residual aluminum liquid from being submerged.

the size of the ceramic foam filter out plate used inside the aluminum plant must healthy the clear out box, and the matching hole among the two should be as small as possible.

After the aluminum liquid filter out is used repeatedly, the filter out plate could be deformed, the force of the clear out plate will be choppy, and the clear out plate will often break suddenly at some point in the filtering system.

therefore, when the Casthouse is deformed, it should get replaced without delay.


The current marketplace call for excessive-grade aluminum alloys is increasing, and end customers have higher and better pleasant necessities.

In trendy, the demand for high-grade aluminum alloys is developing within the path of thin-walled, excessive-strength, and smooth processing.

Such cast aluminum alloys have increasingly higher requirements for the purity of molten aluminum.

currently, the most commonly used filtration generation is the ceramic foam filters' filtration era.

The filtering effect of this technology will increase as the porosity of the clear-out plate will increase.

then again, its filtering effect is still some distance behind the deep bed filter.

For the production of excessive-end merchandise, deep mattress filtration is suggested for procedure configuration: degassing device + deep bed filtration tool + solid ceramic filter.

Ceramic plate filtration is used earlier than casting to avoid media loss because of deep mattress filtration, which reasons too many inclusions to accompany molten aluminum casting, resulting in lots of waste.

And according to the output and manufacturing plan, take into account the corresponding deep bed preheating technique (online or offline). The process configuration guidelines for the use of tubular filters: degassing device + tubular filters (as a minimum parallel), most of the aluminum processing establishments in Japan use this association.

which will obtain energy saving and emission reduction and form an “electrolytic aluminum-aluminum processing” business chain, some businesses use electrolytic aluminum liquid as uncooked substances to produce metallic ingots.

since the impurity composition of electrolytic aluminum is complex and there are many non-steel slags, it's far encouraged to use a ceramic clear out device before the tubular filter.


The harm of metallurgical defects to aluminum processing deformation manufacturing and the mechanical residences of the very last product cannot be unnoticed.

consequently, attention must be paid to the purification remedy of aluminum soften.

before the filter is used, the fuel and slag content material is simply too excessive, on the way to reason the ceramic foam clear out to block.

therefore, including a degassing tool earlier than filtering could make the purification process of liquid aluminum more smooth.


After cleansing the Casthouse, observe a layer of BN refractory to the inner floor of the CFF Casthouse, after which lightly area the Casthouse Cff filter on it.

correct preheating is an important a part of using ceramic foam clear out plates. incorrect preheating strategies often lead to the following problems:

Preheating of cracks;

The filter plate can not be began (aluminum liquid can not skip via);

The stress head is too high; the clear out plate is floating.
