| 摘 要： | 检测了工业用Al2O3过滤器和SiC过滤器与液态铝的润湿性并在工厂使用以上2种陶瓷过滤器过滤铝液。实验结果表明：Si C过滤器比Al2O3过滤器更易于润湿液态铝。提高液态铝与过滤器的润湿性有助于铝液透过过滤器,提高夹杂物的去除率,同时,易于去除与铝不浸润的杂质。

| Abstract: | The wetting behavior between liquid aluminium and substrates made from industrial Al2O3 and SiC based ceramic foam filters （CFF） was investigated. The same CFF filters were also tested in plant scale filtration experiments. The wetting experiment results show that the SiC based filter material is better wetted by liquid aluminium than the Al2O3 based filter material. This indicates that the improved wetting of aluminium on a filter material is an advantage for molten metal to infiltrate the filter during priming. Also, better wetting of Al-filter might increase the removal efficiency of inclusions during filtration due to better contact between filter and metal. Non-wetted inclusions are easier to be removed. |
