The hydrogen remaining in the castings can form casting defects such as pinholes and looseness. Therefore, when purifying the cast aluminum alloy melt (also called refining), it is necessary to remove the gas and inclusions in the aluminum melt.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5415\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/02\/What-Is-Degassing-Aluminum.jpg\" alt=\"What Is Degassing Aluminum\" width=\"500\" height=\"400\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/02\/What-Is-Degassing-Aluminum.jpg 500w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2021\/02\/What-Is-Degassing-Aluminum-300x240.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">\u062c\u062f\u0648\u0644 \u0627\u0644\u0645\u062d\u062a\u0648\u064a\u0627\u062a<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">\u062a\u0628\u062f\u064a\u0644<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewbox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewbox=\"0 0 24 24\" version=\"1.2\" baseprofile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/what-is-degassing-aluminum\/#What_to_Use_to_Degas_Aluminum\" >What to Use to Degas Aluminum<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/what-is-degassing-aluminum\/#What_is_Degassing_Aluminum_with_Degassing_System\" >What is Degassing Aluminum with Degassing System<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"What_to_Use_to_Degas_Aluminum\"><\/span>What to Use to Degas Aluminum<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>At present, aluminum melt purification methods such as flux are usually used to produce cast aluminum alloy. The main components of the used refining flux are chlorine salt and fluoride salt. The gas produced by the chlorine salt or fluoride salt will absorb impurities or hydrogen in the melt during the floating process to achieve slag removal and exhaust. This process usually requires continuous stirring. Although this refining method is relatively simple and low in cost, the chlorine salt or fluorine salt produces less gas, and absorbs less impurities or hydrogen in the melt. The slag removal and degassing effect are not ideal.<\/p>\n<p>\u062a\u0642\u0646\u064a\u0627\u062a \u0627\u0644\u0625\u0639\u0644\u0627\u0646\u0627\u062a <a href=\"https:\/\/www.aluminiumceramicfiber.com\/ar\/online-degassing-equipment\/\">\u0645\u0639\u062f\u0627\u062a \u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632 \u0639\u0628\u0631 \u0627\u0644\u0625\u0646\u062a\u0631\u0646\u062a<\/a> has become an indispensable supporting equipment on the assembly line, providing online uninterrupted degassing for molten aluminum.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_is_Degassing_Aluminum_with_Degassing_System\"><\/span>What is Degassing Aluminum with Degassing System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The set inert gas is injected into the molten aluminum through the rotating graphite rod and rotor.
