Ceramic Filters For Foundry

Ceramic Filters For Foundry are used for cast aluminum ingots and aluminum rods. Ceramic filters have been widely used at home and abroad, they save production costs. In order to achieve the best filtering processing technology, a reasonable configuration of the filter is very important.

For the production of industrial and architectural aluminum rolled products, such as ingot casting or extrusion round ingot casting, only ceramic filter for foundry can be used to meet product quality requirements. Single-layer filters or double-filtering methods can be selected according to product requirements.

For the production of high-end products, the process configuration recommendations for using deep bed filtration: degassing device + deep bed filtration unit + ceramic filters for foundry. The ceramic plate filter is used before casting to avoid the loss of media due to deep bed filtration, which causes too many inclusions to accompany the casting of molten aluminum, resulting in a lot of waste. And, according to the output and production schedule, consider the corresponding deep bed preheating method (online or offline). The process configuration recommendations for using tubular filters: degassing device + tubular filter (at least two in parallel), most of the aluminum processing enterprises in Japan adopt this arrangement. In order to achieve energy-saving and emission reduction and form an “electrolytic aluminum-aluminum processing” industrial chain, some enterprises use electrolytic aluminum liquid as raw materials to produce ingots. 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 final products mechanical properties cannot be ignored. Therefore, it is necessary to pay attention to the purification treatment of aluminum melt. 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 process of purifying molten aluminum more smoothly.
