Filtration is a necessary step to optimize metal quality and downstream finished products. Inclusions can originate from a variety of sources during the production process, including surface oxide films, eroded furnace refractories, and insoluble impurities like carbides. Ceramic foam filters offer a simple, reliable, and cost-effective method to remove inclusions. Filtering with CFF is a supplement to metal treatment within the furnace, such as fluxing and degassing or inline filtration.<\/p>\n![\"\u0627\u0644\u0645\u0631\u0634\u062d\u0627\u062a](\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/06\/Ceramic-Filters.jpg\")

The bonded ceramic particle filter has a filtering effect of 90% for particles of 10-25\u03bcm, but the smaller the inclusion, the worse the effect, and it has no effect on inclusions less than 6\u03bcm.<\/p>\n
The rigid ceramic filter has a filtering effect of more than 50% for particles larger than 1\u03bcm and smaller than 10\u03bcm, and 95% for particles larger than 10\u03bcm, but the efficiency is very low, and the flow rate is generally only 0106\uff5e0107cm\/s. The filtering effect is related to the filter structure parameters (such as porosity, average micropore size, thickness, etc.), melt flow state, inclusions, and the physical and chemical properties of the melt.<\/p>\n
The filtering effects of the above ceramic filters all drop sharply with the increase of the flow rate. Therefore, the control of the flow rate and the available area of \u200b\u200bthe filter hole is the key links that affect efficiency.<\/p>","protected":false},"excerpt":{"rendered":"
