Sometimes liquid flux is also used as a filter medium. In addition to the mechanical barrier effect of the packed bed, there is also adsorption, dissolution, or chemical interaction between the filter medium and the slag. The advantage of this method is that there is a large contact area between the melt and the filter medium, and the filtering and slag removal effect is better than the mesh filter method. Generally, the thicker the filter layer, the smaller the particle size of the medium, and the better the filtering effect. However, if the particle size is too small, it will affect the melt flow rate and reduce productivity.<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Rigid_Microporous_Aluminum_Liquid_Filtration_Method\"><\/span>Rigid Microporous Aluminum Liquid Filtration Method<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are two types of rigid microporous filters: ceramic microporous tube filters and <a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/portfolio\/ceramic-foam-filter\/\">\u0645\u0631\u0634\u062d \u0631\u063a\u0648\u064a \u062e\u0632\u0641\u064a<\/a>s.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ceramic_Microporous_Tube_Filters\"><\/span>Ceramic Microporous Tube Filters<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The ceramic microporous tube filter is made of corundum sand of a certain particle size and low-silicon glass as a binder. It is formed by pressing, drying at low temperatures, and sintering at high temperatures. It is a rigid filter with uniform pores. When the metal melt containing the slag is passed, the slag is separated from the metal melt due to the friction, adsorption, inertial sedimentation, and other effects of the pipe wall, and the metal melt can pass through the micropores. This method can filter out particulate inclusions smaller than the pore size and is one of the most reliable filtering methods. The disadvantage is that the filtration cost is high, and sometimes the grain refiner may be trapped.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_9273\" style=\"width: 442px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-9273\" class=\"wp-image-9273\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-300x225.jpg\" alt=\"\u0645\u0631\u0634\u062d \u0631\u063a\u0648\u064a \u062e\u0632\u0641\u064a\" width=\"432\" height=\"324\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-300x225.jpg 300w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-1024x768.jpg 1024w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-768x576.jpg 768w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-1536x1152.jpg 1536w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/IMG_20230926_164156-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><p id=\"caption-attachment-9273\" class=\"wp-caption-text\">\u0645\u0631\u0634\u062d \u0631\u063a\u0648\u064a \u062e\u0632\u0641\u064a<\/p><\/div>\n<h3><span class=\"ez-toc-section\" id=\"Ceramic_Foam_Filter_Plates\"><\/span>Ceramic Foam Filter Plates<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>\u0627\u0644\u0640 <a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/portfolio\/ceramic-foam-filter\/\">ceramic foam filter plate<\/a> ( CFF) is a sponge-like porous ceramic product plate, it is made of alumina, chromium oxide, etc. CFF filter is the most economical aluminum liquid filtration medium.
