多孔陶瓷过滤器用于过滤和净化铝液中的非金属杂质，对保证铝制品的质量非常重要。

熔融金属通常含有夹杂物形式的杂质，这些杂质在精炼过程中不会被去除。为了获得用于薄板制造、细拉丝和精密铸造的先进金属原材料，通常需要将熔融金属通过过滤器以去除这些夹杂物。

特别是，熔融铝通常含有夹带的固体，这些固体对最终的铸造金属产品有害。这些夹带的固体在熔融金属凝固后作为夹杂物出现在最终铸造产品中，并导致最终产品的延展性降低或最终产品的光洁度和阳极氧化性能较差。夹杂物可能来自多个来源。例如，夹杂物可能来自表面氧化膜，该氧化膜破裂并夹带在所得熔融金属中。此外，夹杂物可能来自不溶性杂质，如碳化物、硼化物等。或腐蚀的炉子和槽式耐火材料。

It is fired at a high temperature to produce the ceramic foam filter.

Porous ceramic filter uses elastic sealing devices or gasket-type seals to seal the filter plate in place. The seal surrounds the filter plate at the beveled corner of the filter plate.

The gasket seal ensures that there is no leakage in the installation and provides an effective separation medium, which is essential for easy disassembly.

In addition, since gaskets or sealing devices prevent metal from entering the sealing surface of the holder unit, their use greatly simplifies cleaning and effectively extends the life of the unit by eliminating the problem of metal corrosion.

In addition, due to its elasticity, the gasket can provide sufficient friction to fix the filter body in the proper position in the bracket or filter.

No need to use other types of compression devices.

弹性腐蚀密封装置不应润湿特定的熔融金属，抵抗其化学物质，并且应具有足够的耐火性以承受更高的工作温度。
