Hydrogen gas disperses in molten metal as it would if it were released in any confined space. It will maintain a constant concentration throughout the melt.<\/p>\n<p>Hydrogen gas can migrate in liquid metal almost as fast as it can in air. Therefore, it is unnecessary to bring every ounce of metal in contact with the inert gas. The efficiency of aluminum degassing is determined by two factors, the transfer rate across the metal\/gas interface and the total surface area available for transfer.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-3800\" src=\"https:\/\/aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Alcan-Smelter-Aluminum-Degassing.jpg\" alt=\"\u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a \u0645\u0646 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645 \u0641\u064a \u0645\u0635\u0647\u0631 \u0623\u0644\u0643\u0627\u0646\" width=\"400\" height=\"320\" srcset=\"https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Alcan-Smelter-Aluminum-Degassing.jpg 400w, https:\/\/www.aluminiumceramicfiber.com\/wp-content\/uploads\/2020\/06\/Alcan-Smelter-Aluminum-Degassing-300x240.jpg 300w\" sizes=\"auto, (max-width: 400px) 100vw, 400px\" \/><\/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\/alcan-smelter-aluminum-degassing\/#Alcan_Smelter_Aluminum_Degassing\" >\u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a \u0645\u0646 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645 \u0641\u064a \u0645\u0635\u0647\u0631 \u0623\u0644\u0643\u0627\u0646<\/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\/alcan-smelter-aluminum-degassing\/#Aluminum_Degassing_Unit\" >Aluminum Degassing Unit<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Alcan_Smelter_Aluminum_Degassing\"><\/span>\u0625\u0632\u0627\u0644\u0629 \u0627\u0644\u063a\u0627\u0632\u0627\u062a \u0645\u0646 \u0627\u0644\u0623\u0644\u0648\u0645\u0646\u064a\u0648\u0645 \u0641\u064a \u0645\u0635\u0647\u0631 \u0623\u0644\u0643\u0627\u0646<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Traditional hydrogen degassing systems bubbled specialty gases (Chlorine, Freon, or SF6) through the metal to speed the hydrogen transfer across the metal gas interface into large bubbles.
