Casthouse Molten Aluminum filter Medium is used to forged aluminum ingots and aluminum rods. Ceramic foam filters were extensively used at home and overseas, saving production prices. with a view to attain the pleasant filtration remedy method, it's miles very vital to configure the filter reasonably.

The damage of metallurgical defects to aluminum processing deformation production and the mechanical properties of the very last product can not be neglected. therefore, interest have to be paid to the purification remedy of aluminum melt. earlier than the filter is used, the gasoline and slag content material is too high, a good way to motive the ceramic foam filter out to dam. consequently, adding a degassing device earlier than filtering can make the purification process of liquid aluminum more clean.

For the manufacturing of business and architectural aluminum rolled products, inclusive of ingot casting or extrusion spherical ingot, ceramic foam filters can most effective be utilized in casting to fulfill product exceptional requirements. single-layer filtration or double-layer filtration may be decided on consistent with product necessities.

Casthouse Molten Aluminum filter out Medium

For the production of high-quit products, deep bed filtration is suggested for technique configuration: degassing tool + deep mattress filtration tool + Casthouse Molten Aluminum clear out Medium. Ceramic plate filtration is used before casting to avoid media loss due to deep mattress filtration, which will reason too many inclusions to accompany molten aluminum at some point of casting, resulting in a number of waste. And in step with the output and manufacturing plan, take into account the corresponding deep mattress preheating technique (on-line or offline). The process configuration tips for using tubular filters: degassing device + tubular filters (at the least parallel), most of the aluminum processing establishments in Japan use this association. that allows you to obtain electricity saving and emission discount and shape an “electrolytic aluminum-aluminum processing” business chain, some enterprises use electrolytic aluminum liquid as uncooked materials to supply steel ingots. for the reason that impurity composition of electrolytic aluminum is complicated and there are many non-steel slags, it's far encouraged to apply a ceramic clear out device before the tubular clear out.

Filtered with molten aluminum

After cleansing the clear out container, coat the internal surface of the CFF filter out box with a layer of BN refractory material, after which lightly place the foam ceramic filter plate on it.

accurate preheating is an essential part of the use of ceramic foam filters out plates. incorrect preheating techniques often lead to the following issues:

Preheating of cracks;

The filter out plate can't be commenced (aluminum liquid can't pass via);

The strain head is too high; the filter plate is floating.
