Ceramic foam filtration for casting is considered a major breakthrough in the aluminum industry and is widely used in semi-continuous casting and continuous casting. The filtering function of ceramic foam filters has been widely used in most aluminum foundries. In the smelting process of aluminum alloy, non-metallic inclusions are produced due to the unclean material […]<\/p>\n","protected":false},"author":1,"featured_media":4892,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[86],"tags":[],"class_list":["post-4891","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"yoast_head":"\n
